What people say after we leave

"Called at 10:40 on a Tuesday night in January with a house at 54 degrees and two kids. Someone actually answered. Tech was here inside an hour, found a failed pressure switch, had the part on the van. Price was what he quoted at the door."

"Three companies quoted us. Keystone was the only one who measured windows and went in the attic before giving a number. They weren't the cheapest, they were the clearest. Install crew laid down drop cloths and hauled the old condenser away."

"Our 1948 house had a furnace older than my marriage. They did the install in one day, rebuilt the plenum, and added a humidifier. First winter our upstairs is finally warm and my hardwood stopped gapping."

"Turned my garage into a shop and needed heat and AC without touching the ductwork. Two heads, one outdoor unit, clean line hide on the outside wall. Quiet enough that I forget it's running."

"Same tech most visits, which I appreciate. He caught a rusting condensate pan before it dumped water in my basement. They've never once tried to sell us a system we didn't need."

"They talked me out of the biggest unit I asked for and explained why. Documented the load calc and left me the paperwork. Electric bill dropped about forty dollars a month compared to the old heat pump."

"I run a 4,000 square foot deli. Rooftop unit died in a heat wave. They got a temp cooling plan in place same day and replaced the unit that week, working around our hours so we never closed."

"Big outfit told me I needed a whole new system. Keystone came out, tested it, replaced a capacitor for a couple hundred bucks and told me the unit had maybe four years left. That's the difference."
