"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."

"Could not recommend this company more to help you with whatever you HVAC needs are. Knew I would need to replace my A/C system at some point and that day finally came. Absolute Comfort was there the next day to give me a quote. I chose to get a full system (AC & Furnace) and their price beat a quote from another company by $1,500.. and the competitor quote was for only the A/C. The installers were professional and personable despite the attic being extremely hot on the day of installation."

"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!"

Heating and Air Conditioning questions, answered by experts

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.

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

Both evaporator coils and condenser coils are recyclable and contain valuable, sellable metals such as copper and aluminum. Not only is it more earth-friendly to take them to a local metal recycling facility, but you can also trade them in for cash. Also, once the coils are removed from the system, they won’t have any traces of refrigerant, so you won’t have to arrange for recycling Freon or R-410A unless you’re disposing of the entire AC system.

No. HVAC, which stands for heating, ventilation, and air conditioning, includes all of the systems that work together to regulate a building’s temperature and humidity levels. In comparison, air conditioners only provide cooling. You can have an air conditioner as part of your HVAC system, but not all HVAC systems include air conditioners.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.
