What Our Clients Have to Say

Home | Testimonials | HVAC Repair | Maryland | AC Repair

"Our home has dual HVAC units. The electric-only unit in our attic has given us issues for years. Rob Will of Will Air inexpensively serviced the unit and babied it along so that we were able to get as much life out of it as possible. Once it was no longer economically smart to keep repairing the unit, Rob recommended a new unit that was affordable, energy efficient and more properly sized for our square footage. The new unit works like a charm and has not needed any service since installation. Rob and his staff show up quickly, and stay until the job is done. Sherry is always friendly and pleasant on the phones and is a pleasure to work with. I will continue to use Will Air for all of my HVAC needs and will recommend them to anyone who needs a trusted HVAC repair company."

Michelle Gavin

"I came home to discover that my air conditioning was not working, which sent me into an immediate panic because I had a baby who was going to be super cranky and I don't fare well sleeping without AC either. I sent out inquiries to several places and hoped for the best because I anticipated most HVAC companies would be slammed during the heat wave responding to similar calls. Fortunately, Sherry from Will-Air was prompt and courteous in replying to my dire request. She even texted me, because she didn't want to risk waking a baby with a phone call, and told me she could have a technician out the next day. The owner came out the next day and walked me through everything that was going on and was very professional. I was so impressed with their service that I've scheduled fall and spring maintenance with them."
