"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."

"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."

"Johnathan Biagi did an excellent job servicing our HVAC to prepare for summer usage. He was very polite, professional and shared information about the air purifier that Horne has available. We like using this company!!!"

"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 am beyond grateful to have met this amazing Father-Son team who came out to help us with some mold and HVAC concerns we were having with a new home we were looking to rent! Upon our initial move-in inspection my husband and I found some concerning evidence of mold and other issues but didnâ t know exactly what to do about it. We were so concerned to sleep there that we texted Blake in the middle of the night and literally the next morning he and his son showed up on our doorstep to see what was going on. I told him I was already experiencing breathing issues and felt poorly so he said that he would get to the bottom of it. Within 10minutes he found the problems and said that he didnâ t even need to test to tell us that where we had just moved into was infested by mold. However, we had just signed a new lease and with this finding needed to get out ASAP! My husband and I opted to do a mold test and sure enough (within 24hrs) it came back positive for over 10 types of moldâ ¦3 of which were leading causes of serious health issues. The biggest shock was that one was shown to cause childhood asthma and we have a 2 year old daughter. I also have a compromised immune system so this also explained why I was already experiencing symptoms in such a short time. As hard as it was to get this â bad result,â it was in fact very good news because it showed us that the home would not have been a healthy place for us to live. As someone who has struggled tremendously with health issues, I have a passion for maintaining good health for myself and our family and preventing disease at all costs. The â costâ of doing the mold test was absolutely priceless because it literally (potentially) saved our family from much further heartache. When he called us to discuss the results I couldnâ t help but cry because as a mother I was just so relieved that I was not alone in my concerns and he reassured us that we were right in feeling the way we did and that he would help us get through this difficult situation. I specifically remember him saying to me â Donâ t worry, Iâ m on your side.â And we had only met 24hrs prior. He proved to be faithful and talked to us about how to proceed with our management company and get out of that place. Sure enough, today we are no longer living in that house and are searching for a new place to live again. However, this time we know what to look for and already have plans to call IES back out before we sign another lease with anyone. It is a miracle that we met them and know they were meant to help us. They literally helped save our familiesâ health and we are eternally grateful! Also, their professionalism made us feel extremely comfortable! They went above and beyond for us and I wish I could give them more than 5 stars!!!!! If you have any concerns about your home or whatever it is, please please please contact them. I am absolutely confident you will not be disappointed! And from the bottom of this mothers heart, thank you gentlemen for your exceptional service!"

"First off, the office staff was friendly and efficient at getting me scheduled for an appointment. The HVAC rep was courteous and knowledgeable and was able to answer all of my questions. The install went smoothly with minimal inconvenience and we were back in business and able to stay warm."

Heating and Air Conditioning questions, answered by experts

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected. 

Your central A/C unit should be professionally serviced and inspected at least once a year to ensure it operates properly and efficiently. This is best done before the peak cooling season. A full-service inspection by a qualified pro will typically include checking safety components for issues like carbon monoxide leaks, verifying cooling components and coolant levels, and inspecting electrical parts like fuses and wiring. Regular servicing enhances efficiency, mitigates potential problems, and maintains optimal performance. Because AC systems contain hazardous refrigerant, professional handling is essential.

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.
