"Great. My daughter contracted Air Duct Professionals to do her home. James, the technician, was professional, knowledgeable and did a quality job. I contacted Air Duct to do my home and requested James. James arrived on time and did an excellent job. He also helped me with a leak with my HVAC Condenser and diagnosed and fixed the issue."

"HD MECHANICAL! I don’t even know where to start, Chris and his team were went above and beyond when doing work at my house. They were honest and and caring which you don’t see from a lot of companies now a days. My wife and i weren’t sure which direction to go in as far as picking a unit to the whole installation process and what we would need. They walked us through it all and were very comforting as they explained every step of the way. I will 10/10 use them again and recommend it to anyone who is needing A/C and heating!"

"Kayvan was a wonderful service tech! He was on time and professionally checked out the water heater and the HVAC system. He was so polite and friendly. He explained the need for a new filter in the heating unit and showed me photos of the unit located in the attic. He also offered to do a friendly deed for free, which I greatly appreciated, He’s a great asset to Service Champions!"

"Trinity HVAC got in touch with me right away and their communication was excellent, letting me know when someone could come out and they showed up as scheduled. Chris inspected the unit inside and outside to assess the situation then thoroughly explained the problem before doing the work. He provided a follow-up email with the invoice showing the detailed items that were repaired and photos."

System works great and really nice guys who take pride in a good job . My only options for ac work from now on is from Ahl air conditioning. Nice job guy's"

"This was the perfect contractor experience. Brian was on time, personable, and obviously experienced since he installed my Wifi thermostat when three other places I called either blew me off or would not do a wifi installation. Also, a very nice handyman who did other work for me tried to install it but could not make it work. Sok I was worried he would encounter problems, but he did the installation quickly, noting that he did not need the jumper provided by Ecobee since the furnace installer had left a fifth wire he could use. (So, he obviously knew what he was doing). He provided me with the code from the thermostat so I could set it up on my phone app. AND...he did all of this remotely while I was in a another state! Finally, what he wanted to charge was only the standard fee I would expect for an HVAC home visit. I could hardly believe it. You better believe his number is saved in my home for any future HVAC needs. Fantastic!"

Heating and Air Conditioning FAQs, answered by experts

Your central A/C unit should be professionally serviced and inspected at least once a year to ensure it operates properly and efficiently. This is best done before the peak cooling season. A full-service inspection by a qualified pro will typically include checking safety components for issues like carbon monoxide leaks, verifying cooling components and coolant levels, and inspecting electrical parts like fuses and wiring. Regular servicing enhances efficiency, mitigates potential problems, and maintains optimal performance. Because AC systems contain hazardous refrigerant, professional handling is essential.

Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.

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.

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.
