"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."

"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."

"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."

"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

The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.

If you don't clean your AC evaporator coils, dirt and debris will build up, which impairs the system's ability to transfer heat. This forces the unit to work harder, leading to inefficient performance, higher energy bills, and frequent breakdowns. Over time, neglected coils can corrode, which may cause refrigerant leaks, or develop mold, ice buildup, and a clogged condensate drain, resulting in poor air quality and an uncomfortable home.

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.

Capacitors are the most frequent part of an HVAC system to experience failure. These components are crucial for starting the motors that power the fans and compressor, but over time, they may become worn or fail due to electrical surges or regular wear and tear. When capacitors malfunction, HVAC systems may experience decreased heating or cooling efficiency, or even total system failure. Replacement or maintenance of capacitors is a common requirement for the optimal functioning of HVAC systems.
