"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 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!"

"I can’t say enough good things about this company. They replaced my electric furnace and did an absolutely excellent job from start to finish. Everything was done professionally, efficiently, and with great attention to detail. The system works perfectly, and the install was clean and well organized. It’s clear they take pride in their work. I’d highly recommend them to anyone needing HVAC work—top-notch service all around!"

"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

A blockage in the ductwork may prevent air from flowing through the vent. If some rooms in your home are very hot or cold and another isn't, that can be a sign that a vent is blocked. Another sign of a blockage is a buildup of dirt or dust around the vent. In either case, a duct installer or cleaning service can investigate the issue for you and recommend a course of action.

Because of the improved efficiency, ACs with higher SEER ratings tend to cool down your home better than models with a lower SEER. Higher-SEER AC units have a higher cooling capacity and a lower energy demand, meaning they may help cool your space faster without running up the electricity bill.

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.

No. Your furnace does not run your air conditioner. Both units use the same system of ductwork to move conditioned air throughout your home, but you can have a furnace without having an air conditioner and vice versa. Furnaces are only for heating your home. You can buy a system that does both, however, like a split system or a heat pump (yes, heat pumps cool, too).

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.
