"I came home on a warm Friday early evening from work to find that our AC was not working. After making one call to another company who serviced our unit years ago and getting their voicemail, I waited a couple of hours then contacted my friend Maggi from Tyler. She responded immediately and the technician, Jonathan had the AC up and running by 9:30 the next morning. Thank you!"

"We were referred to Cawiamca in Old Saybrook, CT, 860-661-5913, by Fujitsu United States, to fix our Split System air conditioner that stopped working on the hottest day of the year. Cawiamca technicians responded immediately. They are professional, efficient and personable. They analyzed the problem and fixed it for a very reasonable fee. We couldn't be more pleased with the service they provided. We will certainly use Cawiamca if needed again."

"From start to finish it was a very positive experience. Shane explained everything and answered all my questions when he came out to give me an estimate on the project. Brandon and Brian showed up on time, completed the job in a timely manner and cleaned everything up when they were done. They showed me how to operate my new mini split AC system before they left. Shana was also very helpful when I called the office. The project turned out great. I would highly recommend Onofreo Home Comfort Systems."

"Y and M Air Duct cleaning provided an important service in a way that was transparent and professional. Our house is noticeably cleaner as a result of the service. They were punctual, polite and clean. They did not cut corners and showed me what they were doing and cleaning every step of the way. The world would be better if more contractors had Y and M's work ethic."

"Very knowledgeable owner-operator. Prompt and personable. He repaired our 30-year-old central ac unit and did not try to upsell us to a new one. He was very thorough in his inspection of our system. I will use him again when we decide to replace our ac."

Air Conditioning FAQs, answered by experts

No, not all HVAC systems have a fresh air intake, but there are many advantages to having one. For example, a fresh air intake can boost the air quality inside your home and help your furnace run more effectively. Plus, it can make your house more energy efficient, possibly saving you money on your utility costs.

The cost of R32 refrigerant is about the same as the cost of R410A refrigerant, the most widely available type of refrigerant today. However, R32 systems use about 20% less refrigerant than R410A systems, making the refrigerant less expensive overall.

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.

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.

Yes, HVAC zoning systems offer energy savings by allowing precise temperature control in different zones in your home. Rather than conditioning the whole house uniformly, these systems direct airflow where needed, preventing energy waste. Tailoring comfort to specific areas reduces energy consumption and lowers utility costs, making HVAC zoning an energy-efficient choice.
