I knew I needed new ductwork and that I would need to buy a new unit in the next few years. To avoid getting swindled, I decided to get unbiased information from a consultant who would not be selling me equipment. David Brown and ConsultAir came highly recommended and I have not been disappointed. David created Manual J, S and D reports and a duct system layout, with quick replies that include thorough and easy-to-understand answers. As I gathered my first quotes from HVAC contractors, I got pushback on using a consultant’s drawings – some refused, others offered elaborate sales routines and scare tactics to persuade me to use their own drawings and equipment instead. I contacted David with questions about what I was experiencing, and he confirmed my suspicions about one contractor and offered additional guidance so I felt fully armed going into additional quotes.
If you are thinking of doing any kind of heating or cooling in your home don’t take a chance by trusting the local HVAC person. They have one agenda… To sell you an overpriced system and get the job done as quickly as possible. I learned this because I had 5 different bids and 5 different sized systems from each installer. How could this be I wondered? Well…it turns out that there is a real, systemic, and calculated way of finding out how big of a system you need for your home.
There are manuals and load calculations that can be done to properly size your system. After much searching on Google I stumbled upon David Brown and ConsultAir. He was the person I was searching for. He did all the load calculations, the calculations for the ductwork and even offered some very helpful tips along the way. David should be your first call when looking to install a system. I cannot recommend him highly enough. Thanks David!!!
I contacted David Brown at ConsultAir with a somewhat complicated HVAC project. Even though he is in Florida and I’m in Washington State, I was confident I had found someone good when local contractors in my area gave him a very positive two thumbs up. David was very courteous and fun to work with, and he was spot on working with me from a technical point of view from clear across the country. Even as a non-HVAC guy I could follow him well, and I never once recalled hearing a word suggesting impatience. The final product is quite reasonably priced and very well laid out for duct installers to follow. I would guess I will save at least $1000 per year or greater by doing this right. Thanks David for coming through with the product you promised.
Hello, I would like to take a minute to share my experience with David Brown; who did the HVAC design. He did my design 2 years ago and I waited to write a review because I wanted to go throw a season of cooling and heating. After 2years of close examination I want to tell everyone the design is amazing. The house is 96’ long x14’ and I have put 12 temperature sensors in every room and the units cooled and heat the house exactly on the money, degree difference between all the rooms in the house, that alone will tell you how accurate the calculation and design is. I’m extremely happy and the money well spent. I do suggest if you build a house, do not really on the HVAC installers, they are just installing the unit and they are NOT design and calculating your heating and cooling loads. David Brown is amazing person. God bless him and his family.
David is an industry expert and an exceptional person on top of that. He helped me tremendously and does an unmatched professional job every time in a timely manner while communicating every step of the way. The value you receive working with ConsultAir will pay for itself before you even start your project.
Filled out their online form and got a response promptly. He offered a wealth of expertise and info and really set me on a good path. The way it worked out, I didn’t end up needing their services, and he was completely honest about that. But even though I won’t be getting the pleasure of being a customer, that didn’t stop David from giving me some excellent advice for my situation. This guy has a heart for helping and if you need honest service from good, honest people, give them a shout.
As a geothermal contractor, I have worked with David directly on many projects over several years. I can say with complete certainty that his level of expertise and professionalism are second to none and have been instrumental to the success of our installations. He is always committed to accurate calculations and offering his knowledge and expertise, a total pleasure to do business with on all fronts! Looking forward to many more projects.
Recently, I had been experiencing elevated humidity levels inside my house. I wanted some objective advice from someone that was not looking to sell me systems or equipment, so I called David of ConsultAir and was absolutely blown away by his knowledge and professionalism. David asked all the right follow-up questions, confirmed some of my theories and debunked others, and took the time to educate me in great detail on the relevant issues. I highly recommend David and ConsultAir to those seeking to better understand HVAC systems and the dynamic issues involved in designing them.
I cannot recommend ConsultAir enough. I am 3 hours away, and all business was done over the phone or email. David was timely – the day I finished giving him the information he had my calculations completed! In town it would have taken months. He has different rates for how quickly you need your calculations and drawings. I recommend him no matter where you live in the US. He checks local ordinances and is on the ball. Best service!
David is a great resource to know and helped me get my calcs for a remodel very quickly and with no hassle. The best part is that almost 3 years after his initial work, I emailed him out of the blue to ask about my second story AC system that needed to be replaced and he had all the data and calculations on hand and could immediately recommend a system with no hassle. I was blown away to see that kind of customer support! ConsultAir is programmed in to my phone as my go-to load calculations company, and they should be in your address book as well.
This will save you money!
This was well worth the money. Quick and easy to work with. The heat and air guys wanted me to buy 7 tons and after it was all said and done I only needed 3.5 tons. Was a great service to capitalize all of my energy efficient components of my new house.
ConsultAir did a fantastic job for me as an owner builder. They took time to make certain they understood our house design and personal needs here in Phoenix, and presented system options and rationale for their recommendation. I was able to confidently get bids from HVAC contractors knowing I was not going to be sold an oversized system – several tried. We’ve been in the home a year now and the system is indeed meeting our expectations. I would never rely on an HVAC contractor to provide the design for a new house build, and would happily use ConsultAir again.
I own an architectural service in the metro Phoenix, Az. area and I was in need for this new thing called manual’s S,J & D which I was dumbfounded about. I was highly recommended David to help me out with this difficult resubmittal process. I gave David a call and he spent about an hour going over everything; I was very impressed. He delivered what I need three days earlier than I was expecting and he also spent two more of his own time going over and checking everything for me. Being a greenhorn on this matter, I am very grateful for his help and knowledge and will and do recommend him to anyone.
Thanks again David!
Superior Design and Service
As a design/builder in Dallas/Ft. Worth with a specialty in green construction, I knew I needed an expert to design a system for my own west-facing home. David took a tremendous amount of time designing the most innovative system possible to maximize energy efficiency. My HVAC contractor, who has worked on million-dollar homes for 20 years, said David’s design and hours of assistance totally changed how he will install systems from now on. I cannot recommend David highly enough. He went above and beyond my expectations with his knowledge, professionalism, time commitment and dedication to the project.
While in the process of finishing up a small renovation I was doing on my condominium near Miami, Florida, the local building department notified me that my new and already installed AC system, including ductwork, was not properly installed or permitted. To make matters worse, I soon found out that not only did my AC contractor have some licensing “issues” but that he was also not capable of providing the engineering reports that the inspector was requiring. This is when I contacted ConsultAir.
When I first called ConsultAir, I spoke with the owner, David Brown. I was surprised at the amount of time David took discussing my situation before I had even placed an order. David let me know up front that there was a chance that my newly installed AC system could be larger than the building codes will allow. A few days after placing my order, David confirmed that the system was significantly larger than the building codes will allow and that the only option I had would be to replace it. By this time, David was also pretty familiar with the issues I was having with my AC contractor and so he took it upon himself to help me manage the entire process from start to finish.
It’s hard to put into words just how complicated and frustrating this whole ordeal has been for me and I’d probably still be trying to sort it all out if I hadn’t found ConsultAir online.”
My wife and I are average people, living in an average neighborhood, but that doesn’t mean that we can’t have a great HVAC system! After getting 3 quotes from local and national HVAC contractors, it was evident that pushing hardware was their #1 priority…the bigger, the better, for their commission! None of the quotes included duct work design or replacement, nor were the vendors interested in doing the calculations, they just wanted to sell hardware. Our air conditioning equipment was already 15 years old and the duct work original to the house from 1966. David took the time to explain all functions of our HVAC system, their relationship to each other and the pluses and minuses of replacing some or all the parts. We decided to replace everything at the same time. We hired a local contractor to install the HVAC equipment and my wife and I installed the duct work ourselves based on David’s design. The fruits of our labor came when the outside temperature got down to 11 degrees, yet it was very comfortable throughout the house.
David and ConsultAir are all around five-star – Professional service with quick response, attentive to the details and to my needs.
I originally asked David for help designing a forced-air heating system, which was finalized and submitted with my building permit application last fall. Approval was a breeze. After construction started I had a change of heart and decided to upgrade to radiant floor heat. I called David to run the new calculations which I needed for equipment sizing and for the building department. David worked through the details on the phone with me, and I had the new calculations in less than 20 minutes. Can’t beat that service!
My wife and I employed David Brown to design HVAC for our dream retirement home. David gave us a great usable working plan, one that we could do some of the work ourselves. David helped us with sizing requirements and with some space difficulties. David told us he would not be finished with the plan until we were happy with the plan. We couldn’t be happier with the working plan that David provided for us. After living for years in a house where the plumber designed the system and all the faults that came with that we are looking forward to the comfort provided by ConsultAir in our custom designed plan. David’s fee has been the best money we’ve spent on our house so far. You just can’t go wrong with ConsultAir and David Brown”
I recently contracted with ConsultAir to perform a Manual J, S, and D for a custom home i am building (General Contractor). The experience was very positive. I had previously performed a Manual J analysis on an install i did about a year ago, so i have some experience on what to look for. David Brown was very thorough about collecting all the data needed to get the most accurate heat loss, heat gain, equipment and duct sizing. He was particularly good at explaining the various options for fresh air recovery as well as the benefits of single stage, two stage, and modulating equipment.
His expertise helped catch a few errors that would have been made by the HVAC contractor. Great experience!”
David is one of the best. A perfect blend of someone that has done HVAC in the field and knows how to apply the load calcs necessary to put together a comprehensive HVAC installation. I have had other load calcs done by other companies that just let the software do the work, however that never winds up working in the field. David understood those disconects and put together a plan that thought about the required loads and how best to meld the installation and duct runs that would supply the air. His design has me going into my next project with a confident HVAC plan. thanks David!
I have an engineering background and have done quite a bit of research related to the issues I’m having. I went into the conversation thinking I needed a Manual J done on our house.
During our hour-long conversation, David first talked me out of doing this, and proceeded explain why, quickly adjusting his explanations from Homeowner 101 to more technical, in-depth conversation that was appropriate to my knowledge level without missing a beat.
Thanks to him, I have a much better set of expectations, a better understanding of how things should be operating, and a plan to further optimize my system.
I wholeheartedly recommend his services.
David helped me out in so many positive ways. His Manual S & J calculations reflected the actual design and construction of my house. They were thorough and accurate. Throughout the process, he educated me on building science, HVAC equipment, and HVAC operations/performance. It was an extremely valuable interaction. I highly recommend using ConsultAir.
I found Consult Air on the internet and called to inquire about their services for a new home I was building in the Houston area. I was very fortunate to speak with the owner David Brown. Rather than initially sell me services he spent over a half hour trying to understand my needs, inform me about residential air conditioning and provide sound advice and insight to resolve an issue I was having with my builder. I was very impressed with his knowledge and understanding of the industry and the needs of the consumer. I give Consult Air and David the highest recommendation for customer service and technical expertise.
Quality work is provided when someone has a passion for the work they do.There is no way I would build another house without ConsultAir. I received far more than just an excellent job. When we were done, I had a clear understanding of what they did, why they did it, and things to look out for. Since then, I have had friends and family take on the task of building a home. All of them have used ConsultAir for their HVAC designs and could not be happier with the systems performance. Thanks for the great work.
Service was outstanding and done in a very timely manner. Dave the owner actually designed and helped walk me through the install. 5 months after install I had a few questions and he was on it like when he first started my project. I would highly recommend hos services to anyone looking for a load calculation or duct design. Thanks Dave
Excellent and Highly Professional
I am an owner-builder in Central Florida who recently retained David at ConsultAir to provide HVAC design services for our home construction project. Because I have a professional background in construction, I had some level of perspective as to what to expect from a professional in David’s role. Throughout our interactions, I found David to be both extremely knowledgeable and professional at all times. He was patient and thorough in working through all of my questions and needs – David possesses a strong ability to communicate technical concepts in lay terms for those who are not experts in this scope of work. All deliverables that David provided were very professionally prepared and were extremely thorough – I make my living picking apart construction-related deliverables, so I would know. David’s technical expertise is clearly very deep and I highly recommend ConsultAir to anyone looking for HVAC design or consulting services. Thanks David!
Attention to Detail and Service
David took the time to design a system for my home that was better engineered and more efficient than what I would have received from a “design build” HVAC contractor. His scientific approach along with his real world experience is uncommon in the industry. Even after my design was complete David continued to answer questions and provide valuable insight. He is attentive and responsive, two qualities in short supply these days.
My experience with David Brown of Consult Air was very positive and I would highly recommend him and the HVAC sizing and advisory service he provides to anyone. My wife and I just completed building a new home in Flower Mound, TX and I wanted confirmation that our builder’s HVAC contractor was sizing our AC & heating system properly as well as designing the size and configuration of our ducts efficiently. In addition, we were installing spray foam insulation in the attic to increase efficiencies. We contacted David and provided him with a floor plan of our house and all the other information and data he needed, and in return, he supplied us with load calculations for our required AC tonnage, a very efficient duct system design and other valuable information that was very helpful in our dealings with our builder. David’s pricing was very reasonable and he answered follow-up questions without charge. Call him if you want to feel confident you’re getting the HVAC system you need.
I don’t normally write reviews but when I was looking into ConsultAir there were no reviews anywhere so here goes.
I’ll start with the finish, David (owner) did an excellent job on my plans that had a lot to be desired. “Warning” have your plans well drawn up, David will pick through them with a fine tooth comb, he is very picky but you will end up with a heat / cooling load calculation that he is confident in. My house is more energy efficient than most here in the North Woods of Wisconsin and I expect to save over a thousand dollars by going with ConsultAir verses how many square feet most installers would use to size equipment. This part of the review is 5 stars for sure!
Now the reason for 4 stars, for people that have not worked with a small business before you can get lost a bit. I know several small business people and they never turn down work no matter how busy they are just be aware of this and keep on him you’ll be rewarded with an excellent plan that will save you money.
As a side note, It was actually hard for me to give him a 4 star rating but it is truthful. David spent so much time with me because of my bad plans that in the end I felt like it would be great to share a beer or two with him and talk fishing.
David was great to work with. He designed HVAC for a personal residence for us and was very knowledgable, easy to talk to, open to ideas, and good at troubleshooting potentially problematic areas of design, but most of all he was responsive. When we submitted to our local building department, they called for several unnecessary corrections. David’s responses to their concerns caused them to quickly reverse course without further question. Highly recommended.
I contracted with ConsultAir to get my HVAC Manual J, D, and S calculations/report that I needed for my building permit submittal for an addition/remodel, a new requirement by the county. David rushed it out for us at a reasonable fee, which I much appreciated. They have also been great about making adjustments to the report when I found an error on the original plans I provided. I highly encourage you to reach out to them for your project.
ConsultAir provided the expertise necessary to properly size and design the HVAC system for a home I am building. With this information, I was able to educate myself on the cost of materials and cut through the clutter often found in exorbitant contractor bids, saving me thousands in the end.
I am building a metal building in rural southeast Texas, so my case was not straightforward. ConsultAir not only performed the Manual J calculations, but provided valuable advice on several aspects of my HVAC project. The value of all this information and calculations far exceeds their fee. I recommend very highly.
If you are building a new home then you need to contact ConsultAir! I cannot say enough about how refreshing it is to do business with a company like ConsultAir. All of the detailed HVAC design work they do is top notch and totally based on your goals for a HVAC system, not what an installer is trying to sell you. Having them provide honest professional opinions makes difficult decisions during construction much clearer and will certainly save you money, in addition to having a HVAC system that performs flawlessly.
ConsultAir was a pleasure to work with and extremely knowledgeable. I had major problems with a split system sweating and put too much time and money trying to fix the problem. We found that since refacing, insulating and doing stucco on the outside of my property along with new impact windows, the load calculations and duct sizing were completely off. He spent his time to help me find the best solution and shared plenty of his knowledge with me. I will definitely use him again and would suggest him to anybody that needs their load calculations properly done.
Very helpful, didn’t try to sell me in any direction, explored all options and walked me through each scenario in order to make the best decision. I highly recommend him on any project. Very knowledgeable on other aspects of construction as well. I had to edit my post to add that this guy is ridiculously dedicated – my installers were trying to change things on me for their convenience and Dave was very quick to support or clarify the reason behind the design. This guy is worth every penny.
David at ConsultAir was flat out amazing. I had one HVAC company after another come out and pitch what they wanted to do, not what was needed for what I wanted to accomplish with my HVAC. David custom designed my solution and I couldn’t be happier. I highly recommend him!
I called David because I was having some HVAC issues in my house. He took several hours of his time to discuss the issue with me and what might be happening. David was very thorough and his hunch on what was happening ended up being correct. I highly recommend David’s services.
I was working with another engineer for 2 1/2 months and they could not get my energy calculations and load calculations correct. So I reached out to David at ConsultAir – he was very knowledgeable and it took him two days to do what the other guy couldn’t do in 2 1/2 months. I would definitely recommend everybody to use him and I will definitely be using David for future projects.
I needed a HVAC Manual S, J, D to get permits for our South Jersey beach retirement townhouse. Our HVAC contractor was dragging his feet and holding up the whole house renovation. I thought I could buy anything or get any service on the internet. Luckily my Google search led to Dave. I told him my problem of just needing something to give to the city to get my permits. He convinced me that I didn’t want to do a garbage in, garbage out document and compromise a major system of my renovation. It was very easy working with Dave to give him the information he needed to design a properly sized and efficient system for our home.
Update: we moved in almost 2 years after we gutted the townhouse. We had one of the hottest, most humid summers in south Jersey, and we were very comfortable despite my wife keeping it like a meat locker. No problem keeping the upstairs cool at night, which is not the case with the other townhouses in the community. So happy we found Dave and took the time to do it right.
During our recent remodel I contacted David Brown at ConsultAir to make sure we were doing the right things with regard to the HVAC system. David has been a great resource and has always been quick to respond to questions or concerns. A true professional!
ConsultAir and David Brown were fantastic to work with. I feel much better having the system and load sizing provided by a third party who has no incentive to sell me something I do not need. David took the time to help us redesign a couple of areas when we had problems due to other equipment changes.
From the initial email to the first Manual J load ran, this has been a great experience. It’s nice to find others that are passionate about their trade. David got the load done on time and very detailed, which saved our company time and money. Will be using again and again.
Trying to separate fact from fiction? Need answers, not a salesman? Looking for someone with real world experience who uses advanced technology and standards? I called ConsultAir and spoke to David Brown and got the personal, professional answers I was looking for in a fast, friendly and timely manner. I would recommend David’s consulting services to anyone who wants the job done right.
David is amazing! ConsultAir is second to none in knowledge and customer service! I have used them for multiple new construction projects and always feel like top priority. 5 star service!
David Brown was a pleasure to work with! He was able to provide the calculation ahead of schedule and provided great details. I look forward to using his services again in the near future.
David was excellent in helping me figure out how best to approach our HVAC requirements for our second story renovation, walking me through different parts of the problem and suggesting different solutions at each point.
David talked with me for over 45 minutes and gave me very beneficial advice that resolved my issues. I would recommend him to anyone looking for a professional to design their residential HVAC system.
David was super helpful and responsive! Perfect and unbiased resource for all furnace and/or air conditioning questions. Great experience!
I recently hired ConsultAir to perform a Manual J on a house my wife and I were building. They did a great job of explaining how important it is to have an air conditioning system that is sized correctly for my home. I would highly recommend this company to anyone needing this service.
It’s Friday night, 8pm. ConsultAir is closed but we sent in the online contact form and figured we would hear something from them by Monday or Tuesday. I then started to read Google reviews on them, and the phone rang – it was David. Now that is prompt service.
Mr. Brown was very helpful and top notch with my energy calculations. I would recommend him to anyone in need!
I would certainly recommend this company to anyone. ConsultAir was very knowledgeable and prompt with all responses. I even called to have a few items addressed per the county and received revisions within a matter of moments. Customer service is an A+. It was a pleasure working with this company.
One of the best experiences, thank you!
Working with them to get our HVAC problems fixed.
Excellent customer service! David went above and beyond anything I expected to receive when reaching out for help with a design project! Will definitely be a repeat customer!
