"The technician's (Tim and Chaun) that did the installing of my HVAC were courteous and professional. Tim made sure everything was working to his satisfaction before he left and told us he would check back in a day or so to make sure it was functioning properly. My wife and myself very pleased. I should also state two years ago we had a new HVAC installed by Swift and continually had problems with it. After many service calls with little luck correcting the issue, Swift installed a new unit. Five more stars to Swift for integrity!"

"Job was completed in one day. It was convenient. I woke up with no hot water. Called Hill's (it was on a Friday) around 10am and they had one of their plumbers call me right back so I could explain the problem. He gave me a time that he would be at my home. He called me when he was on the way. He arrived at the time he had said he would (3:30pm). He showed me the problem. Water heater was leaking. (It was 22 years old). It needed to be replaced. I didn't have time or a truck to go purchase one myself. He replaced it and we had hot water by 6pm."

Heating and Air Conditioning FAQs, answered by experts

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

Unfortunately, a freon leak will persist even when your AC unit is off. The freon in the AC unit is under pressure no matter the status of the system, so it will continue to drip through the leak even when you shut off the entire unit. It will continue to leak freon until it’s completely empty.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.
