"SAFE AIR HVAC LLC did an outstanding job installing my new AC unit and furnace. From the first visit to the final walkthrough, their team was professional, knowledgeable, and extremely efficient. They took the time to explain my options, helped me choose the right system for my home, and provided a very fair price. Installation day went smoothly—they arrived on time, worked cleanly, and made sure everything was set up perfectly. The new system runs quietly and keeps my home comfortable, and the difference in air quality and efficiency is noticeable right away. I was especially impressed with their attention to detail and the care they put into their work. If you need a new HVAC system installed, I highly recommend SAFE AIR HVAC LLC. They truly go above and beyond."

"We were very impressed with A & C Heating and Cooling. Their online scheduling tool was convenient, user friendly, and there was a variety of time slots available. The appointment follow up, reminders and arrival tracking map were timely and helpful. Our technician, McKinley, was amazing!!! He was very courteous, knowledgeable and efficient. He diagnosed the problem quickly, installed the needed part, and ran tests to ensure the unit was running at peak performance. He educated us about our unit by explaining how it operates, what caused the problem, and how the replacement part would remedy the problem. We are VERY satisfied with their service. We give this company and our technician our highest rating, and we would highly recommend them to anyone in need of quality heating and cooling installation or service. ."

Heating and Air Conditioning questions, answered by experts

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.

Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.

When your HVAC system is loud, a few different causes are possible. If you have loose connections or bolts in the hardware, they can rattle as the system runs and vibrates. If you have an extremely dirty furnace filter, it could cause the system to generate noise. More commonly, an excessively loud HVAC system indicates a malfunction in the system. You may have a blower motor that is close to failing or a compressor that is breaking down. These issues require an immediate inspection.

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.
