"I was very impressed with Rich throughout the entire process of working with him. He gave us the best price for the same appliances the other companies were going to install. Rich was the only one who actively followed up and answered all of my questions prior to hiring him. When we did hire him, he arrived on schedule and completed the job on schedule as well. I was very impressed with his professionalism. I would recommend Rich to anyone in the market for a new HVAC system. I will hire him again for maintenance and other HVAC needs."

"Super HVAC showed me what I needed to do to make my A/C more efficient.  Spent about 20 minutes at my house and refused payment for his time.  He said he did nothing and so he charged nothing.  I even stated that he spent time there, but he would not accept payment. 
What a wonderful attitude and one that will make me recommend them to anyone looking for HVAC.  I certainly will call them when I get ready to make any HVAC changes in the future.

"They did a wonderful job from beginning to end - were mindful of our budget and did not recommend more than we needed. They also offered a great financing option. The HVAC contractor arrived as scheduled, completed the job quickly, and cleaned up completely. The furnace has been in operation now for over a month and we have had no problems."

Heating and Air Conditioning questions, answered by experts

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

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.

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.

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.
