"September 2019, my water heater broke and TC HVAC Services replaced it with a new water heater. And they also fixed my AC and fridge. Recently, in October 2019, TC HVAC Services installed a new humidifier in my home. Mr. Thea Chea, the specialist was professional, honest, and he answered all of my questions. The repairs and installation were completed in a timely manner. And costs were reasonable and fair. I would definitely use TC HVAC Services again and I have recommended TC HVAC Services to my family and friends. Thank you, Mr. Chea and TC HVAC Services LLC."

"So happy I worked with Magna for my issue! They came within 45 minutes of me posting on Angie's List... that has to be some kind of record. They diagnosed the issue quickly, clearly communicated what was needed and what the cost would be, and I moved forward with it. My AC was back up and running within an hour. Highly recommend! I've saved Magna Tech's phone number in my contacts and they will be the first company I call every time I have an HVAC issue."

"McCrea replaced a 20 year old HVAC system with a new Trane 4-ton XL16i condenser, XV80 furnace and new coils. The salesman, Mark, was very responsive to my request for quote changes or additional items, including financing options. He was very knowledgeable and patient through the entire process as I worked with other companies for competing quotes. As a result of Mark’s recommendations and excellent pricing, I added on a new Aprilaire 1210 filter box (including replacing a portion of the return duct work/box) and an Aprilaire 600M whole house humidifier. I was able to schedule install four days after signing the contract. The installers, Charles and Christian, arrived on time and removed the old and installed the new in about 7 hours. They provided an overview of system operation and cleaned up so well, you couldn’t tell that a significant installation had occurred. I would recommend McCrea, especially Mark, Charles, and Christian to anyone...they were professional and did an excellent job. My home is so much more comfortable with a system that will be better on the summer and winter utility bills."

"VS earned my trust and confidence and is now on my "use in the future list"! He was on time, professional and best of all, made only the repairs needed at a less than expected price. Over the years I have used a number of different HVAC repair services but I will say, VS has been the best. Highly recommended!!"

"I do not know how anyone could rate this company less than 5 stars. Terrone came to my property the day after I posted on Home Advisor and advised me that my system was pretty much a complete loss, dangerous and needed to be replaced. I already knew he was right. Within in 2 days he had a crew at the property to replace the entire HVAC system. During the replacement process they corrected two every significant problems that existed with the old system. First, the air filter couldn't be changed because the return was jammed in behind a water tank, that made it extremely difficult to change, which it hadn't been in a very long time. They installed a return vent that allows the filter to be changed from the living room, which was really great. They also found that there was an emergency shut off for the furnace, but it was behind the unit and could not be reached. They moved, replaced and marked the new value so that it was easy to see and easy to use if needed. The system is in an awkward place and his crew was able to remove the old system and but in the new system without having to remove a wall, which I thought they would have to do. Their work was great, well done and significantly less expensive than what others had quoted me. Like I said in the beginning, I don't know how anyone could rate this company less than 5 stars. If I have any more HVAC issues, Terrone will be the first person I call."

"I recently had SwiftPro conduct an inspection and assessment of my HVAC system, and am very satisfied with the service. Tyler and Moises were highly professional from start to finish, wearing boot covers to respect my home, and thoroughly explaining their findings. They were efficient, courteous, and took care to ensure everything was done to a high standard. I will likely be using them to replace my entire furnace and air conditioning unit. I highly recommend SwiftPro for anyone in need of trustworthy and quality HVAC services!"

"My outside HVAC unit was no longer working, however, everything on the inside of the house was. Isac W. was able to diagnose and solve the problem in a short amount of time. Isac was courteous and the price of the service was as expected. I would definitely recommend this business for your HVAC needs."

Heating and Air Conditioning questions, answered by experts

Dry mode positively impacts indoor air quality by reducing excess moisture, which stops the growth of mold and mildew. By maintaining optimal humidity levels, dry mode creates a less hospitable environment for allergens and airborne pathogens, improving overall air quality. However, it's essential to ensure proper ventilation to prevent stale air accumulation.

Common signs of insufficient return air include uneven temperatures, with some parts of your home feeling hotter or colder than others, and noticeable differences in air pressure between rooms. You might also observe that more air is blowing in rooms closer to the AC unit. Leaky air ducts can also be a related issue or clue.

Yes. Return air vents are responsible for gathering and pulling in the warmer air. Once they draw it in, your system conditions the air by removing the warmer molecules from it, allowing your air conditioner to dispense the cooler air back into your home. Not only does this create a more comfortable environment for you, but it also keeps your air conditioner from overworking, resulting in lower energy bills. 

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.
