"Diagnosed a leak, recharged the system, and I can sit comfortably in my home again! He was honest and up front, didn't try to gouge me or sell me a service I didn't need. This is the first HVAC tech I've used, and he'll be the only one I ever use."

"It was covered under warranty. They actually installed our HVAC and it just wasn't cooling and it was a real simple thing that he was able to fix me up with. I have know them and used them for a long time. They are always prompt. They are very professional in what they do. They pick up after themselves. Very helpful in the information that he provides and making sure that any issues we are dealing with, he takes care of."

"I sent a message through Angies List and they responded almost immediately. I was called and given a 30 minute window of their arrival, plus the technician's name. Then the technician called me when he was on his way. He talked to me then went to work and immediately diagnosed the issue (chipmunk chewed the wiring argh!). He gave me a quote which I felt was quite reasonable and the repair only took about 45 minutes. After that, we spoke further about the Hvac (it's pretty old), he said it seems to be running well but obviously has some age to it. He advised I don't need it replaced but may want to consider some ongoing maintenance. He was nice and professional and answered all of my dumb questions. I would definitely call them again.

"We recently had a brand new HVAC system installed by Chisholm, and the entire experience was excellent. From the initial consultation to the final walkthrough, their team was professional, knowledgeable, and easy to work with. They took the time to evaluate our home and helped us choose a system that fits both our space and our budget. The installation crew arrived on time, worked efficiently, and made sure everything was cleaned up afterward. They also took the time to explain how the new system works and answered all our questions thoroughly. Since the install, the system has been running smoothly—quiet, efficient, and keeping our home consistently comfortable. We’ve already noticed an improvement in both temperature control and air quality. If you’re in need of HVAC work, I highly recommend Chisholm. They’re honest, skilled, and truly care about the quality of their work and customer satisfaction."

"Air today got me fixed up after my AC unit stopped working 18 months after install. When contacting the company that installed the unit, they openly admitted that the unit was installed incorrectly which caused the failure. After quoting us a seemingly high price to fix it, we looked at other options. We contacted Air Today and they got us fixed up quickly for a fraction of the cost! Not only was the cost better, the techs that came on site were knowledgeable and kind. Mark and Keith were thorough in explaining the issues and patient in helping us understand the needs. They recommended several different options to fix the issue at varying price points. The techs were respectful of our home and were careful not to make a mess or track dirt inside. We work with contractors frequently. Mark and Keith were top tier. All four Air Today employees we talked with through the process were helpful and easy to talk to. Would highly recommend Air Today to family and friends!"

Heating and Air Conditioning questions, answered by experts

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

Yes, you can potentially save $60 to $200 by handling your own air conditioner capacitor installation. However, capacitor replacement comes with the risk of electric shock. Only attempt this if you have the knowledge and protective gear to carry it out safely. Otherwise, we recommend hiring an HVAC pro with the experience to properly diagnose the issue and avoid damaging other parts of your AC unit.

Yes. Your air supply should be balanced. The return and supply ducts need to maintain that balance, and this only occurs because an equal amount of air should be entering and leaving your HVAC system. Changes in pressure, extreme weather, and blocking vents with furniture or your stuff can make the air supply unbalanced and cause your home to get too cold or hot.

High humidity is one of the most common reasons for air vents to sweat or produce condensation. When the cool, dry air from your HVAC unit meets warm and moist air in your home, it will cause condensation. Insulating your ductwork can help prevent this. If you live in a very humid region, a dehumidifier can also help.
