"This was a complex retrofit tankless water heater installation and out of 30+ companies called and solicited for this project, Brett and Dunn's HVAC was the only company to 1) entertain performing the installation correctly (gas line sizing and calculations), 2) had prior experiencing working with tankless heaters, and 3) took the time to work with me on a long list of specifications. These are bulletproof systems if the installation is done correctly and Dunn/Brett took the time to ensure the install was on point and everything went smoothly. They also installed a softener and filtration system. Everything went well from bid to install and I highly recommend Brett and Dunn's - will use again as I could not be more pleased!"

"Had new hvac, furnace, and hwh installed. Furnace had a couple of air leaks between a coil and furnace which I fixed myself. Hvac was spot on. Hwh failed first inspection, but was corrected in same day. For the premium price paid, these issues should not happen. Quality 4.5 because of these issues, same goes for value. Customer service is very good. They are very professional, work looks very good, clean worksite afterwards. I would recommend, but don't think about negotiating price with them. Their labor is very high."

"Frankly, I rarely give reviews but this encounter warranted it. Here we go: On a 100 degree, sweltering Saint Louis afternoon, my 23 year old HVAC system finally called it quits. I knew I was looking at a full replacement and a repair would simply cost more money in the long run as the replacement was imminent. I did my due diligence and got multiple bids. I contacted John Hively and he said he could make it out that night (it was already 6:00 when I contacted him!) He showed up just 30 minutes later and did HIS due diligence checking all the components of the HVAC system before offering his diagnosis, verdict, and the cost of parts and labor. He was incredibly knowledgeable and his proposal was very reasonable considering the extent of the project and he was very competitive against the several other bids I had received - not to mention his warranties were unrivaled. Now, this is where the story gets really good... Because of the heat and my staying at a hotel because my house was 86 degrees, he rushed the appointment... While everyone else was giving a 7-14 day approximation, he was back the next day to drop of equipment and then the following day for the install. From 72 hours of making the call I had cool air again. He estimated a 4-6 hour completion time and his *extremely professional* crew was done in 5. They gave me a run-down on maintenance procedures, double checked everything to make sure the system was functioning as it should be, and were on their way. I can confidently state that John Hively provided the best residential service of ANY kind I've received since being a homeowner. I won't even waste time with bids on any HVAC needs again because Hively Heating and Cooling is my new go-to HVAC service provider. Do yourself a favor and call John. - A very happy homeowner"

Heating and Air Conditioning questions, answered by experts

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.

Yes, a mini split AC system can replace central air—and quite easily, too. Since mini splits don’t require ductwork, homeowners can convert their central air system to a mini split to save money and energy. Consult with an HVAC professional to learn more about the process of replacing your central air with a mini split.

The time it takes for an air conditioner to dry fully after cleaning depends on the unit's size and humidity levels. Most units will dry within two to four hours after cleaning, but check the manufacturer's recommendations for drying times. Make sure to leave the unit off until it's completely dry.

AC leaks are common, and an HVAC pro can usually fix them. You may be able to resolve some leaks on your own, but a professional HVAC technician should handle most AC leak repair. If left ignored, an AC leak could cause serious damage to your system or leave you with expensive water damage, usually leading to more costly repairs or replacements.
