"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"

"The HVAC unit broke in the home we have for our son in our back yard, the first time we had to turn the heat on this season.  The wonderful staff at Acosta made it a priority to get out that day and evaluate the problem.  Unfortunately, we needed to replace the 20 year old system.  They came back out three days later with the new unit, thermostat, and duct work. Though the proposal called for reinforcing the existing duct work, when the crew was under the house they realized that it needed to be replaced.  Despite the additional work, the crew still managed to complete the installation in one visit and without incurring an additional expense.  Both the service crew and installation crew called ahead to let me know when they were arriving, and showed up on time.  They cleaned up every bit of the old system and removed all the trash.  They were pleasant and professional.  

I anticipate having to replace the unit in our house as well due to age sometime within the next year and my first and only call will be to Acosta Heating and Cooling.  Thank you again for the great service."

"I spoke with Mike on a Tuesday and was able to schedule an appointment that same day. Which was great! The HVAC Tech Brandon arrived on time, answered all of my questions, he took the time to explain to me what he was doing, and serviced my unit which didn't take long. I was pleased with his professionalism and would definitely use Unique Air again and recommend their service to my family,friends, and coworkers. Thank you, C.P."

"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."

"Reagan called to ask about my issue with my AC, and made time to come by my house the same day. He called prior to arriving and came at the time he said he’d be here. He was professional, courteous and informative. I would recommend him, and will absolutely contact him again for future HVAC needs."

Heating and Air Conditioning questions, answered by experts

Indications of an HVAC problem include inconsistent heating or cooling throughout your home, unpredictable temperature changes, or inadequate air flow from vents. Abnormal sounds such as grinding, banging, or hissing, and unpleasant smells like mustiness or burning are also potential warning signs. A rise in energy costs without an increase in usage may also imply decreased efficiency. An HVAC system that frequently cycles on and off or cannot maintain a stable temperature is malfunctioning.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

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.

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.
