Cornerstone HVAC

Cornerstone is one of the best in the business as far as dependability and flexibility, Shane is one of the smartest guys around as far as diagnostics and troubleshooting goes.

Had a boiler relief valve replaced, work was done spot on in record time, Thanks for the prompt response Shane and Jorden 👍🏻 …

First time customer, my central air wasn’t working properly. Shane came out first thing next morning, within 1/2 hour my a/c was back. Shane was very thorough, professional and price was reasonable. Thank you Shane and Cornerstone!

Shayne has been to our house on two different occasions now and we've always had a great experience. Once was to install ductwork in an unfinished room and the other time was to fix a broken gas valve on one of our furnaces. Pricing is super reasonable and he has always shown up for the job! Highly recommend.

Incredibly knowledgeable, timely and professional HVAC technicians. Highly recommend!

Shayne and his team completed several plumbing and renovation projects on my home. My hardwood floor was installed beautifully and efficiently and my gas range was recently converted from electric cook top. Highly reccomended for plumbing, heating/cooling and renovations, thank you Cornerstone!

Shayne was a very work oriented young man. He was on time and did great work. I will contact him for more jobs. I was disappointed as I did contact him for more jobs and was basically blown off. However the job I did get him originally for was done well.

Shayne was really quick with showing up after business hours to fix my heating and communicated my problem really well. Highly recommend him.

After replacing my boiler and indirect water heater and having to come back several times to make sure everything was running correctly, all I can say is Shayne was SO professional, did an amazing job and I would hire him again in a second.

Shayne installed a new boiler and water tank this week. Very professional and superior workmanship. Would highly recommend this company. 5 star +!

Quality work,reliable,A1

On time. Problem solvef

Referred by a friend. I called them up and explained the problem. They gave me a two hour window timeframe as to when the technician could stop by. The technician arrived and located the problem and was able to resolve it. Price was reasonable for short notice service that was resolved in same visit.

Being in the service industry myself for over 50 years communication with your client is job one in my book, these guys understand that perfectly. Nice to see the next generation carrying on that type bussiness model, rare these days.

I went with Cornerstone after several neighbors in my community recommended it. Scott tuned up my AC unit last week and it has been running more efficiently since. Besides the tune-up Scott replaced one part and added a liter of refrigerant. All in all his price was very reasonable. He was very knowledgeable and freely shared maintenance advice and tips on my HVAC, water hear and sump pump units. He struck me as very honest and caring about doing the right thing for the customer. I plan on going to Scott for future maintenance needs, and I highly recommend him to others.

Scott arrived on time and was professional. I found his pricing to be quite fair and he was trustworthy. I will definitely use Cornerstone again for any future HVAC needs.
