I was not shut out while work was being done. The workers engaged with me to get to the desired end. I will put Keystone at the top of the list for the next project at our house."

"It is so hard to find trustworthy contractors - from big companies who look to constantly upsell and take advantage of homeowners who don't know the mechanics to independent contractors who overpromise and under-deliver - John is the consummate professional! Gave me options, great advice, and quick service! Will not hesitate to call him again, and highly recommend others to do the same!"

"Woke up with no heat! Right before Christmas! Harris responded instantly and sent out someone to check the problem. Due to incorrect installation, rain had gotten into the improperly sealed roof vents, which in turned fried the transformer, inducer and circuit board. They were at my place bright and early the next morning installing a brand new furnace, more efficient and quieter, with a 10 year warranty. Arranged financing and were finished by 3pm. Everyone from my first phone call to the last service tech was professional, polite, knowledgeable and all around pleasant and really nice people. They will be my go to for heating, AC, plumbing and electrical from here on in. Glad I found them!"

"Haller removed an old ac system and replaced it with a heat pump. The work included installing an additional return in the family room (split level home) to return air from the lowest point in the house. The crew was knowledgable, their work was neat, and they cleaned up at the end of the day. The work was completed in 2 days and the new Carrier system works great so far. Looking forward to see how it performs next fall and winter."
