What Our Customers Are Saying

Shane was a pleasure to have. He's very friendly, honest, thorough and diligent as a professional. His rates are also quite reasonable. Shane repaired all existing pipework and other small fixes (with no extra charge), returned the hot water heater back to Reliance and setup the warranty for me on my new hot water heater. Will definitely reach out to him again for any future work!

Very satisfied with the "repair" service Shane provided. I quoted repair because other big contractors charge you $150 to only tell you that you need a new AC or furnace. Or they will charge another $150 for repair service. Shane came to look at my AC condensation issue. He was very professional and on time. After resolving, he explained me the cause of the problem and gave me some tips for future.

Shane came same day when we called him to repair our duct vent. He performs quality work and provides informed recommendations. He is polite and very professional and did a terrific job fixing our duct with very competitive price. I will use this company again and have no hesitation in recommending them to friends.

Shane installed my vents in my basement to get it ready for inspection. This was everything from a couple of dryers, range hood, and a few return and supply lines. The inspector recommended some changes and he made the updates. While I had to have him come back several times because of the logistics of working with Framers and Plumbers, he was able to accommodate.
