"On time, neat, effective. Technicians were professional, personable and flexible. I gave a "B" on cost because I may have done better if I shopped around but having the company that was installing the HVAC install the electrical as well was a good convenience and one-stop shopping."

"I appreciated being able to speak with someone in the office to explain my situation (leaking water heater), and having someone come to my home so quickly to go over my options for dealing with the problem. Dylan, Aaron and the entire crew were so professional and knowledgeable about the on-demand hot water system we chose to install. They were a pleasure to work with, and I would highly recommend them to friends in need of similar services."

Heating and Air Conditioning questions, answered by experts

If your AC condenser is nearing the end of its life, it might leak fluid or make loud or unusual sounds (like grinding or hissing). You might also notice that it isn’t heating your home as evenly or effectively as it once did. Also, an aging condenser will have to work harder to cool your home, which may force it to use more power and drive up your utility bills.

Yesh, heat pumps can easily cool homes when the weather reaches over 100 degrees Fahrenheit, just as powerful air conditioners can. The key is sizing the heat pump correctly for the size of your home and your climate. A local heat  pump professional can help you determine the right size and type for your home.

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.

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.
