Wow! Our air conditioner broke on a weekend during the recent heat wave. Our home's previous owners had used Mann-In to install a new air conditioner several years ago, so we called them to fix the unit. On Monday morning I reached their office and was treated courteously despite a large backlog of calls they were facing. Several times during the morning their service department called me back to keep me informed of my status in the wait list. I was promised a noon to four pm window and the technician came at 2:30 pm. (I was called by the office shortly before his arrival). He was courteous and quickly diagnosed the problem with the unit (a broken capacitor). Within 20 minutes our A/C was back up and running. The material and labor charges we felt were fair, especially given the rush nature of our repair need. After having a less-than-satisfactory experience with another company during a winter-time furnace problem, we were just thrilled! Great customer service, excellent technician!
Description of Work: Replaced a broken capacitor on our Carrier air conditioner.

My heat pump stopped working during a cold spell. Called around 4pm for service. Was told in a very prompt call back that they could come now for double the fee or I could get scheduled in for that day's service and get the regular service fee. I liked the honesty. Services scheduled at 7am next morning for later in day. Wayne was very professional, courteous. Told me my heat pump was about 10 years old with a life expectancy of 2-5 more years. No pressure to purchase new unit.

They were great. They showed up on time and came out before we had company due in town. They were done quickly and got done right the first time. I thought they gave great advice. They re-directed my vents because I had one are without good air flow. It was really nice experience.

Think you can get a quick repair of your heating problem on busy Monday morning in mid-winter? I did, thanks to Angie's List. Here is my opinion. Pro 1: no typical sweet no-clue bimbo on the phone. Instead, the folks on the phone knew their stuff, were straightforward, and were all well-connected and organized, big savings of time and overhead. Pro 2: They did their best to diagnose the problem on the phone in order to send the right guy with the right supplies, so he wouldn't waste time (and my money!) Pro 3: They clearly spelled out the pricing twice before confirming the guy was on the way. Pro 4: They were able to send me somebody within 1.5 hours of my call. Pro 5: The guy was on time, worked fast, and fixed everything in 1+hr. Pro 6: They didn't attempt to sell me any anything else. Con 1: He left some mess behind him. In short, this is your no bull, no warm-and-cozy, but fast, professional and ethical business. I highly recommend them.
Description of Work: In mid-Dec, my heating system blower quit working. They correctly diagnosed the problem over the phone (making me do a few tricks). The repairman showed up within 2 hours and replaced the blower. No problems since.

Office staff was very pleasant and efficient when contacted for appointment. Scheduled a service call for the next day and worked with me to accommodate my schedule. Technician arrived on time and was polite and professional. He quickly identified and rectified the problem (a clogged drain where condensed water escapes)and through the maintenance check, identified a part that needed replacement. Explained the part's purpose, showed me the damaged part and gave me the price to replace before proceeding. Entire visit took less than 1 hour. Excellent experience.
Description of Work: Requested a service call because our heat pump wasn't working. Decided to go ahead and do our fall check-up while they were here.

Their quote was better than any others and they installed within 2 weeks of the quote, on time with no damage to our walls or ceilings. Workers were neat and professional. Used a high velocity system and the quote was still less than what any of the big HVAC companies came in with for a regular system.
Description of Work: Installed duct work and air conditioning system to our home. The house had no duct work or AC previously.
