"A/C wasn't cooling and service tech did some testing. He found that problem was minor and was able to bring our old unit back to life. His quote was fair and we would use him again"

"We were desperate to find someone to repair our central air conditioning unit. We were not able to move into the house and everyone that we called was not able to accommodate us because of the recent heat wave. All Weather was able to get a technician to us within 2 days. Nuri was amazing and showed my husband how everything worked and what repairs needed to be done. By the time he left, we had a cool house and were able to set up our movers. Thanks to Angie’s list, I found a reputable company that was reliable and efficient. We can rest easy! Thank you!!!"

"Varsity installed a new high efficiency gas combi boiler (heat and hot water) for our home. Working with them has been one of the best contractor experiences I have ever had in all my years of home ownership. They are very responsive, care a lot about the quality of their work, use well qualified technicians, and follow through on all their commitments. They follow up on all calls, come when they promise, get the job done and really seem to care about their reputation and work quality. They are a little bit more expensive than some of their competitors, but they are worth the price. Just to be clear - I am not a paid shill. I almost never give such good reviews, and I have been maintaining a home now for a long time."

"Joe responded to my online "request for quote" within an hour of me posting it. He offered to come the next morning and arrived exactly on time. He assessed within 10 minutes that a capacitor in one of our units had blown, probably due to a line surge from a lightning storm, and had a replacement capacitor in his truck. The capacitor was replaced and the repair completed in 30 minutes. He then a quick review of our entire system to assess its overall health. My experience with Joe was so good that I have asked him to send me a service contract to maintain my AC system going forward."
