Kevin is a great HVAC technician. So glad to have a professional and reliable service for the things we need to run well in our home. Got an issue with boiler, or hot water heater? Cornerstone Services is the answer. If you get Kevin, you’re in luck; he’s excellent! This isn’t the first time I’ve called on cornerstone to help during emergency hours annd it won’t be the last. They are the quickest and friendliest service in the area!

The entire team at Cornerstone HVAC is lovely to work with. About a week ago, I called with a furnace that was blowing cold air. The first tech was there to diagnose the problem same day. It seemed it might be motor that needed replacing, and my unit was pretty old, so they would have to order the part. They warned me it might be a few days to get it in, but they were able to reach back out to me the next day to say they got the part. The next morning, they were there to install it. After install, it was clear something still wasn't quite right. The technician did everything in his power to diagnose and take apart my furnace (calling several tech support, shops for parts, etc - going the extra mile) to be 100% sure that my furnace truly was dead. Once they came to that conclusion, they laid out the options for getting a new furnace in terms that were easy to understand. Beyond their great technicians, their sales and customer support are also lovely. It was great to be able to pay for their service with card and have the receipt/quotes emailed to me. As for the installation, Corey and Cameron came today to install my new furnace and were even nice enough to mount my smart thermostat for me. They were in and out in a few hours and were so quiet considering the work they were doing - my dogs didn't even know they were here! In the process of getting this all sorted, I have talked with at least 6 of the employees at Cornerstone and couldn't recommend them enough. Thank you!

We have had a new boiler system installed last week. Corey and Cameron came and installed the unit. They were professional yet friendly. They know their job well. They explained everything and when they left everything was clean. Also working with Kelly and Tom is always a pleasure. Also a spit out to Tracy that doesn’t leave until any problem is solved. Highly recommend this company!

Thank God for Cornerstone's 24/7 service and for Cameron - he is so polite and communicative, really a great asset to this business! Our well pump needed replacement, and Luke and Russell went above and beyond to do the job and make sure our water is clean and safe. I'm so grateful for your knowledge, skills, and more so, your - kindness. In addition, Kelly makes calling the office such a pleasure, she is so personable and accommodating. Thanks for hiring the best, Cornerstone!

I have been using Cornerstone Services for the past year to service my house with heating and plumbing. They have consistently done an outstanding job servicing my furnace on a seasonal basis, only doing the repairs and preventative maintenance that is necessary to keep the system running efficiently. On numerous occasions they have come out on short notice to make sure the house stays heated. As vacation rental, we can not be without heat in the winter months and since we have found Cornerstone everything has run smooth. Recently Cornerstone put in new grinding pumps for our septic system. Another great improvement that helps up keep the house in top shape while renters continually seem to do everything they can to test the limits of our systems. I highly recommend Cornerstone Services for all your heating and plumbing needs.

This is not the first time I have had to have service and installation from Cornerstone. They are always professional and courteous. They always call and arrive when they say they will. I just had a new furnace installed after a service call. The whole team including Luke, Nate, Russell and Garrette got the job done, took the old furnace away and left the place clean. Warrenty and service was explained. They were even able to provide space heaters for my big house to keep us warm. Would recommend! Thank you.

We purchased both our electric hot water heater and gas furnace from Cornerstone almost two years ago. They have been amazingly responsive and able to fix problems that were the fault of the manufacturer. They are a very precious resource.

Excellent handling of my new furnace installation. From the start of the estimating process with Chad, to the scheduling with Kelly, to the installation with Bill & Garrett the process was smooth, professional and flawless. Special callout to the installers Bill & Garrett who were on time, kept me appraised of progress, and thoroughly explained operation and warranty of the new furnace. Overall, I would highly recommend Cornerstone for all your heating needs. I guess another testimony was by a general contractor who was working at my house at the same time who said “Cornerstone is a great Company”.

Tom is an exceptional salesman. Went into detail on boiler installation. Came to my home twice promptly before install took place. Great person.

We have used Cornerstone the past few years and are extremely impressed with their service, attention to detail and quick response when we needed help with a broken system in the middle of the night with temps dipping very low. Blake is always quick to respond and has an excellent staff. Highly recommend Cornerstone.

Furnace went up, it was old and bound to happen. Cornerstone came out fast. Diagnosed the issue and gave me all my options with no pressure. In the end purchased a new furnace through them. The install happened when they said and more than met my expectations. Bill and Garrett were thorough and efficient. Took a little longer due to some existing issues in the system but it is clear they did not cut corners. They left my basement better than they found it, all they way down to sweeping it up. Thanks for the great experience. Highly recommend.

i called C'stone abt adding a short duct to the furnace they had recently installed to keep the supply lines to our washing machine from freezing. Bill and Garrett came prepared with all the parts needed and did the job quickly and, near as i can tell, very well. they called a few minutes before they arrived, which was very helpful.also, the heat pump & furnace the C'stone crew installed in early fall is humming along well.

Woke up to my furnace making a loud racket. Called Cornerstone and the woman said the technician would call me. Bill called within 10 minutes to check and see what the issue was. Told me he was finishing up another job and would be here in about 1 hour. He arrived just short of an hour and got right to work. He figured out the issue in just a few minutes and had my furnace up and running! Not the first time I've had Cornerstone to repair my furnace and I will continue to call them when needed. Highly recommend!

I unexpectedly had to have my furnace replaced and Cornerstone worked with me to get it replaced very quickly, within the week. The three individuals who came to my house to get my furnace put in, and also a hot water tank, within a day and a half we're professional, kind, and we're very helpful especially if I had any questions. When done they explained what they did and showed me everything and answered every question I had and I was very grateful! So I want to thank Shea, Cameron, and Caden very much and for a great job!

I have used Cornerstone for Heating, Water and Plumbing on new construction and home renovation projects over the past few years. They consistently developed high quality solutions for each home including in-floor heating, wall radiant heating, boiler systems, well water purification & integration, and air circulation systems. They have the manpower to complete jobs and deliver on time with high quality. I have done a good bit of renovation work and am a repeat customer.

I found Cornerstone's service from initial phone call to service call to be handled professionally and efficiently. In the office Kelly responded to my concerns and scheduled my service call quickly. Russel called an hour before arrival to let me know when to expect him. He resolved my boiler issue quickly and was professional. Based on my first experience with them, I recommend Cornerstone services.

In October 2021, Cornerstone installed and plumbed a new Utica Boiler system and indirect hot water tank. Recently the boiler started to howl when starting up. Their serviceman immedately knew how to fix the problem (and also lessen my natural gsas usage). He replaced an igniter bent by heat, and hence having a bigger spark gap, That inefficiency cause the howl and sometimes repeated tries to restart. He was in and out in 15 min. All is well now. Fine service!

Russell was excellent, professional and very knowledgable. I cannot imagine better service. I have used Cornerstone over many years and it is always the absolute best service. We had to replace a pump on our hot water lines.

I recently acquired my childhood home and needed a new heating system. As you can imagine, anything like this is overwhelming! Cornerstone was right there EVERY step of the way! I had a good feeling about it as soon as I spoke with Ethan on the phone.My installers...well, I can't say enough about these two! No doubt they had a nightmare to deal with and they were super professional and thorough! Cameron and Shay are absolutely fantastic! Very communicative, informative, and they even helped deal with the propane company on my behalf!Ethan, Cameron, and Shay - Thank you so very much for helping to get this old house back into shape so our family can have a Christmas gathering together under one roof for the first time in a very long time!Folks, if you need a professional HVAC company give Cornerstone a call. You won't be disappointed!

Cornerstone services out of Norwood NY installed a furnace for me. The two people Cameron and Shea were very nice and hard working people. They made sure I understood what they were doing and asked if I had questions. I highly recommend them. Thank you again

My wife and I have been, always please for the annual work and inspection on our old furnace. This year we had our tankless hot water heater inspected and flushed. The front counter and the technician workers are very professional in their work. Have a Merry Christmass and Happy New Year. Keep up the great work.

Cornerstone recently installed two mini split systems in our museum. Our museum is on the National Register of Historic Places. Garrett, Shea and Tracy were extremely professional and sensitive to the special needs of a historic building. Tracy's leadership skills were to be commended. All three are respectful, kind and work well together. This makes the customer's experience a positive one. This team enhances Cornerstone's reputation. I highly recommend them to anyone!Service: Heating system installation

Luke serviced our combination boiler a few weeks ago, and we are so grateful for the excellent service that he provided. He took a great deal of time to ensure the unit was back up and running! He was friendly, knowledgeable, and professional. Thank you so much, Luke, for taking such great care of our system! We will always call Cornerstone for all of our heating needs.

Luke serviced our propane heater, which is an older wall model. We so appreciated his attention to detail and literally cleaning each part, then ensuring its service. What a hard worker- so professional and talented. We surely appreciated it!Additionally, in making our appointment, Cornerstone personnel were so pleasant and responsive. We’ll be going back again to do business here. You simply can’t go wrong, and nowadays, I’m finding that increasingly valuable! Ask for Luke: you won’t regret it.
