I've had an annual contract with Wolff for a few years and they come out 2x a year to check gas heating and A/C and make any needed repairs which have never been very serious ($400 at the most probably). Customer Service is always great, the techs are knowledgeable too and do good work.
My 2 single-stage systems of course were aging and I knew the time would come where I would have to put them down. This year, at age 13, the tech delivered the bad news that it was time. I have 2 A/C-gas furnace systems (original builder grade Goodmans and noisey!). Of course I got more than 1 estimate. Decided on Wolff. My sales person, Brandon DuBois, was outstanding, highly professional, eager, likes his job, likes his company, likes people, knows his 'stuff'; and the company offered good financing, etc. Went with the 2-stage 16 seer Daikin; 2400 square foot 2-level house. Easily scheduled the work to be done within a short time frame out, and because I work they came out on a Saturday. Two crews were sent to get the job done in 1 day. The team leader, Zaid, was meticulous, knowledgeable and concerned. The crew worked great together, too. Zaid didn't leave the job until he was sure the 2 systems were working optimally. I know have 2 beautiful, more quiet systems, more cost effective systems with a best-in-class warranty and Wi-Fi enabled programmable thermostats, just in time for summer! If you're looking especially to replace your systems, definitely consider Wolff for one of your estimates. And if you're looking to make sure your systems continue running, also considering Wolff for their annual contract. The 2 annual check ups are free and any service or repair needed is done at a discount.
