We don’t just promise quality, we deliver it. Here’s what your neighbours have to say about working with Red Seal Mechanical on Google.
Very happy with the service provided! Lee installed a new natural gas line for a pool heater. From our first message to the completion of the job he was quick to respond, and knowledgable. I would highly recommend Lee, if you’re looking for a gas guy look no further.
We had an emergency with our humidifier attached to our furnace (leaking water) and Lee promptly answered our call & was able to come out and diagnose our problem within an hour!
Lee was extremely knowledgeable & honest with his repair. He even followed up the next day to ensure everything was running smoothly. 5* customer service! We are happy to have Lee as our main contact for all future HVAC needs. Don’t hesitate to give him a call.
Lee installed a new furnace for us after our existing one reached end of life. Lee came out promptly when we called him, provided us with options and answered all our questions before we chose the replacement furnace. He was here the next day – removed the old furnace and installed the new one with no muss, no fuss. Lee has done work for us before on our air conditioner and he is always prompt, professional, takes pride in his work and most importantly is honest. Lee is our “go to” and we highly recommend him.
Lee replaced our furnace. Very professional and prompt.
Explains information very well. Reasonably priced. Our “go-to guy”
Replaced our AC two years earlier – same excellent service.
I had an issue with our pool heater. I messaged Lee on a Saturday afternoon and he walked me through a few troubleshooting steps in hopes that it was something I could fix without a service call. When we realized it wasn’t, Lee was at my house first thing on Monday morning and was able to make the fix and get our heater back up and running. His efficiency, dedication, pricing and knowledge are exactly why I call him before anyone else. Thank you Lee!
