"This contractor was responsive, thorough and very fairly priced (no hidden extra s or add-ons ... he is straight up honest). Within two days of his on-site proposal he returned and completed work on our heating ductwork system which was a mess. The under-the-house work is top quality and the system is now working great. We will continue to use Clark and Sons for our total HVAC system in this house and when we build new. You are not going to go wrong with this contractor."

"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."

"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!"

Heating and Air Conditioning questions, answered by experts

During the summer, it’s best to set your AC to 78 degrees when you’re home and awake, according to the Department of Energy (DOE). For better energy efficiency, raise the temperature slightly to 85 degrees while you’re out of the house. The National Sleep Foundation advises lowering your thermostat to between 60 and 67 degrees when you’re asleep.

Signs that your A/C system needs professional service include increased energy bills, uneven or poor cooling, loud or unusual noises, and frequent cycling.

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with. 

Modern AC leak sealants work as a temporary measure to stop refrigerant leaks. You can purchase them at most home improvement stores or on online. When using an AC leak sealant, keep in mind that it’s only a temporary solution, so you’ll still need to hire a pro to install a replacement part as soon as possible.
