"Had new hvac, furnace, and hwh installed. Furnace had a couple of air leaks between a coil and furnace which I fixed myself. Hvac was spot on. Hwh failed first inspection, but was corrected in same day. For the premium price paid, these issues should not happen. Quality 4.5 because of these issues, same goes for value. Customer service is very good. They are very professional, work looks very good, clean worksite afterwards. I would recommend, but don't think about negotiating price with them. Their labor is very high."

"HIGHLY RECOMMEND! Did much research on companies 1st b/c I was aware of scams with duct cleaning. But this company is very legitimate professional - techs and receptionist, all the way around! Top quality service! On time and will answer any questions and explain it all in great detail? very polite and professional. And yes, they will take photos throughout if you want to see exactly the differences of before and after. I had bought a 1959 home which had never been cleaned. See my before/after photos. Before, I kept having to wipe off my counter tops a few times a day because they always felt gritty. After the duct cleaning, they stay clean now - A HUGE DIFFERENCE! The guys were awesome and went above and beyond by also helping me carry a heavy appliance from upstairs to my basement. Very nice guys! They cleaned up any mess before leaving, like they had never there. You will not regret using their service. Lower Price than others too! Thanks Danny & Cameron! Great Work!"

"It went well and he did an excellent job installing my gazebo and pool. This equipment had been sitting in my garage for a year so I decided to give Angie's List another try the first time I had a contractor last year didn't show. Steven was polite and professional and I will be using him again for all of my upcoming jobs."

Heating and Air Conditioning FAQs, answered by experts

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

It’s never a good idea to run your AC without a filter, even just for a night. The filter defends your HVAC system from the dust, dirt, debris, and other grime in your home. Without a filter, those contaminants are more likely to get inside your system and potentially damage it. 

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.

No, you should not run an air conditioner with a Freon leak. If you think your AC unit is leaking refrigerant, shut it off immediately. When you keep using a leaky air conditioner, it could damage the unit and release more refrigerant. After turning off the AC, have an HVAC pro come take a look at the unit.
