We used Keystone for the first time when we woke up and found out our furnace would not come on. This was on Sat morning and we looked at local companies who would do 24/7 service. We left a message and very quickly Jeremy called us and was over within 30 minutes. He was able to diagnose and fix the problem very quickly and for a reasonable price. Our problem turned out that we needed to replace the Ignition Control, which he did. We definitely would recommend this company and we will use them again.

I will expect to use them. I get a service package from them and they will be checking my air conditioning this spring. It’s a packed deal. It’s nice because if you do that, they come out and you don’t have to wait. For one year with tax is $208, the price is $198, so the rest is tax. They are good at making appointments and keeping them. They will call you ahead of time when you are the next customer, so that you are expecting them. I have always been able to reach somebody there. Last my air conditioning didn’t work and I thought it was relatively new, but it was over 10 years old and it needed a new motor. The man that came to do it worked late to get it done. I appreciated it.

Furnace tune-up was done professionally, weather to cold for heat pump tune up. Tech did not have proper diagrams and had my wife and I chasing around for furnace books. Billed $400 filed complaint with better business- Keystone refunded $200. Cost me time & money, Keystone owner overbilled job, will never use again!

I have used Keystone's maintenance for many years to keep the old systems running clean and efficiently.  They have always done a terrific job for us.  After my initial call to Keystone, Dave promptly came out and walked me through my options and pricing for furnace, a/c, air filtration, humidity control and a smart thermostat. I also asked them if they would install a new water heater.  Although they are not in the water heater install business Dave quickly arranged for a trusted local plumbing contractor to put one in on the same day that the new HVAC system was installed.  Less than a week after I gave Dave the go ahead Frank, Steve and Tom, Keystone's professional installation team, showed up on time and went right to work putting down tarps to keep my home clean, removed the old system and began installing the new.  They even moved the new thermostat location to a much better one for more efficient operation.  Once installed they cleaned up the work site and then walked me through the operation and maintenance of the systems.  They explained how the new smart thermostat works and then helped the plumber load the old water heater out and the new one in.  What a team!!  Louis from Affordable Plumbing did the water heater install and he was just as impressive as Dave's crew.  The whole job started at 7:30am and everyone was finished and out by 3:00pm.   I highly recommend Keystone Heating and AC for all of your HVAC needs.  GREAT JOB DAVE AND CREW.

They have a very good reputation.  They came out in the middle of the night. They are really responsible. They do charge more for coming out in the middle of the night. They charge more then anyone else. They do a good job. They come out in the middle of the night and in the middle of the winter. They got it working again.

We have our furnace checked every year. They are very responsive, very courteous and efficient. We had a whine in the new furnace. When the motor would start up, there was this kind of whining sound. I have very sensitive ears and I could hear this. The owner of the company came out many times and he couldn't hear it. He even came the day after Christmas. Our family was here and when he showed up, we were having breakfast with our children and grandchildren. I invited him for breakfast. He had breakfast with us and then did his work. It took a while before he could hear what I could hear. But I think it's because my ears are sensitive. He never ever gave up and said, "I'm not going to come out and listen." He came out eight times to try to hear that sound that I could hear. So, that's pretty good.

They have been very responsive and very courteous. The service was excellent. The people who come here are very efficient. They tell me what they're doing. I really have a lot of good feeling for them. I have a lot of faith and trust in their company. I have told lots of people about them. Our neighbors just had a furnace put in. I wouldn't hesitate to recommend them.

A three man crew arrived at 7:30 am to do the installation.  They were prompt, professional and competent.  They did an excellent job and were very polite.  Before they left, they cleaned up thoroughly and explained the new system to me.

Wonderful - from Dave the salesman visit's to our home. He used to do installs so he knows the industry. Install took 4 hours and 3 men to complete. They walked me thru how to use thermostat & change filter - very professional.

I thought they were very careful and efficient, because they had to take the old furnace out and put a new one. I was very impressed. I needed a magic pack which is a little more expensive than normal furnaces, so I wasn't happy with the price, but that is the going rate for them. They were here when they said they would be, and they were quick. It was a heavy thing, and they had to drag it upstairs, I was impressed.

Dave Katt, the owner, came out to give us an estimate. Once we chose Keystone, Dave called to be sure of every detail ahead of time. The installers arrived on time, worked quickly, and took care not to disturb our home.

I called them after midnight, and left a message. The technician called me back, and came out right away. He tested it, and determined that it was the circuit board that was defective. He had the part in his truck. He fixed it reasonably quickly. He was very skilled, and very pleasant. They have a very good reputation around town also.

They have a service agreement where you pay an extra charge and things like those, and you don't pay extra for weekends if you have the plan. They also replace filters, and those are added in our contract too. John is the one who comes out, and he has been coming to our condo for so long, that he knows what to do, and what I expect. The price used to be low, but it goes up every year. We have had no problems, and we have been very pleased. We have never used any body else. Everything is running beautifully, and we can call them every time we have a question, and so I have had no reason to change. We had freon leak 14-15 years ago, and they came right away to change. I think the price is comparable to what other people have said. They had to bump me one time, because they had to be else where, and they called me to ask if they could delay by a day.

They did a fantastic job.  They did it in a very timely manner.  It only took 1 hour.  There were 3 men that came.  They laid out tarps when they came in to ensure the carpet didn’t get dirty.  They even offered to move something back into my furnace room that was too heavy for me to move at no additional charge.  They were also very good about explaining how to use the programmable thermostat.

They arrived promptly and finished the installation that afternoon. 
Very pleased with the job they did. The new AC unit and furnace both run very quiet. 
I have had a service contract with this company for the past 5 years. I have been very happy with them. I will continue with the service contract.

Workers were on time, polite.  They covered wood hallway floor.  They explained what they had and how the new equipment worked.  They were here about six hours.

Fantastic.  Can't say enough about the company and the people that I dealt with.  On the first day, Dave brought over 4 heaters to keep our house warm until the next day.  They worked well to keep the home sufficently warm.  It was a snowy time.  On 2/7/13, they were forcasting lots of snow for the next day starting early. 
The repairmen were to be here at 6:30am.  It snowed a lot during the night.  They were here at 6:30am.  They shoveled their way to our door and brought in our paper!  I thought they might cancel but they did not.
The men installing the furnace did a fantastic job.  They were never in our way and never stopped working.  They did an amazing job.
I love our new furnace.  I would recommend this company to anyone and everyone.
