"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!"

"Chose Brothers via Angi to determine our heat pump problem. Their assessment led us (given it's age) to decide to replace the system. I obtained multiple quotes and Brothers was priced the best. They promptly installed a new system. All of the guys involved like Matt, Andrew, Shawn & Jamal (forgetting the electrician and another tech guys name, but they all) did an excellent job. I would highly recommend using Brothers for your HVAC needs."

"They are so great.  From Samantha who answered the call, to Steve who came out for repairs they made me feel like my job was the only thing important to them at the time.  When I called back a couple weeks later looking for a written statement of what the professional had done to provide the buyer, they obliged.  I had the information emailed within minutes.  If I was staying in NC I would serisouly use them for all of my HVAC needs without hesitation!  I will recommend them to all of my friends any family."

Heating and Air Conditioning questions, answered by experts

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.

Yes, it's normal for air conditioners to leak tiny amounts of water due to condensation. Under normal circumstances, all excess moisture travels to the drain pan to be pumped through your system's drain line. You should call a technician to diagnose the issue if you're noticing frequent leaking or pooling. It's also important to investigate if your homeowners insurance can cover water damage.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

Yes. It's normal for the AC compressor to cycle on and off intermittently in dry mode as it maintains the desired humidity level. The compressor cycles to prevent over-dehumidification and to maintain a comfortable indoor environment. This cycling behavior ensures efficient operation and optimal humidity control, contributing to the overall effectiveness of the dry mode function in your AC system.

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.
