"Wow what else can I say. Excellent service, Andy was very professional and pleasant. He called me within an hour of my submitting my request via homeadvisor and was at my home later that day. For my HVAC, he cleaned coil, added refrigerant and general service for the HVAC and I am extremely pleased with how fast he was able to help us, and how reasonably priced he was... Definitely recommend"

"Excellent service. Got brand new HVAC units and had the coils replaced. They were thousands less than the other three bids. Came in laid drop cloth to make sure nothing would be tracked in. Very polite and quick and cleaned up when they finished. A++ Service will recommend and hire again."

"I called GSM inquiring about their HVAC and insulation services. I also asked if I could have someone perform a Manual J load calculation (surprise to me, the Manual J calc was free!) as I felt that my existing heat pump was sized too small for my home (2.5 ton dual-zone single stage heat pump for 2200sq ft 2-story house). We agreed on an appointment time, and they sent Kelly out to my house. Kelly was very nice and professional, and did a thorough job explaining what all could be done and what my options were. Due to having so little room to work inside of the mechanical closest, you would have to remove the air handler completely just to wrap all of the duct work. Since I would be removing the old air handler that was 8 years old anyway, I decided to replace the entire system with a new Amana 3-ton 18 SEER dual-zoned heat pump. Kelly also told me they could seal up the hole & the mechanical closet so that hot air could no longer enter that space as well. I agreed to their quote, and they came out a week later (it would've been sooner but GSM wanted to make sure that the new system was designed properly, so they had to architect and design the layout of the new equipment to fit the small space) to do the work. Owen and Jason came out to perform the installation. They were both very professional & thorough, and they did an excellent job with the swap out & installation of the new heat pump. When GSM told me that it would take two days to do the work, I was prepared to be miserably hot trying to sleep at night with no air conditioning. Not only did GSM bring a portable AC unit for me use that evening so that wouldn't be the case, Owen and Jason actually got the heat pump wired and working the first day so I had full AC that evening, and the portable unit wasn't needed! They also insulated the attic space & mechanical closet with spray foam and foam board so the hot attic air will no longer be an issue. All in all, my experience with GSM has been great! They've been easy to communicate with throughout the entire process, they did an excellent job with the installation of the new equipment, and now I can rest easy knowing that everything has been taken care of!"

Heating and Air Conditioning questions, answered by experts

The decision to put your AC unit on the roof or ground depends on the climate in your area, the roof shape, accessibility, and budget. If you live in a warm climate or don’t have existing ductwork, it’s likely best to stick to a traditional AC unit that sits on the ground. However, if you lack yard space, live in a mild climate, and have easy access to the roof, your home may benefit from a rooftop AC unit. 

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

The cost to replace an AC unit averages around $5,900, with a typical range between $3,900 and $8,020. The final price depends on several factors, including the type and size of the air conditioner, its efficiency rating, your geographic region, and labor costs for installation. Smaller units like portable and window ACs are much less expensive, costing between $90 and $550, compared to central or ductless systems. If your current unit is less than 10 years old, repairing it may be more cost-effective than a full replacement.

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.
