Thank you very much, you Guys are the best.
Always, always proficient, professional, complete and honest.
Very professional and competent.
Same day service and the quality of work provided was great.
Colin was excellent and provided detail education about our furnace repairs. He also provided a detailed listing of furnace replacements with cost, labor and warranties.
The technician was very polite & friendly. He did the maintenance check in a timely & efficient manner. I found the furnace filter after he had gone out the door. He was still in the driveway, so I asked if he would change it for me. He was very accommodating.
Brandon arrived on time and was very polite and thorough.
Adam is amazing. He did an excellent job with our air conditioning maintenance
Brandon was very knowledgeable and courteous.
Adam was exceptional as usual. He helped me understand the workings of my system since this is my first air conditioning season in this location. He is always helpful and considerate. I’ve used Keystone for over 40 years. I’d never go to any other company. They are the best.
I have dealt with Keystone for many years and they are knowledgeable, professional, trusting, and friendly.
The technician was very professional and I highly recommend this company.
Brandon was very friendly, helpful and knowledgable in his service and advice for future maintenance of our furnace and air-conditioning system. We would welcome his being our regular service technician.
As always great service, thanks Adam
Tech was very pleasant and Did a great job. Explained a potential issue with the capacitor and gave us the option to repair today or wait until a future date. No pressure.
Our ac condenser was 20 years old and needed to be replaced. Keystone from start to finish was friendly, helpful, honest, punctual and genuinely cared about quality. Keystone quickly responded providing an estimate and installation in less than a weeks time. The technicians were on time, professional and detail oriented. I definitely recommend this company.
Technician was on time answerd all my questions.Good Job
First class in every way.
The technician phoned ahead to let me know he would be here shortly. He was right on time. He completed the work in good time. He saved me a little money noting that the furnace filter did not have to be replaced at this point.
Adam did an amazing job. Came out to check over my AC unit that was having issues last year and advised if I would need new. He was professional and gave an honest opinion without upselling. I was prepared to by new and he insured me that my unit currently is perfectly fine. This customer service alone will make me a life long customer.
