I had a great experience with Brian from Cozy Comfort from initial phone consultation, followed by in home visit on the same night to ensure right furnace was selected as my old one had quit. Great price was competitive and install performed 1 day later and everything works mint! Will definitely use these guys again.

I can't stress enough how happy & pleased we are with our Napoleon BBQ. From the moment we walked into the showroom, we were met with a very friendly greeting.

My wife and I were so impressed with the calm, sincere and gracious demeanor of Brian. He answered all our questions, gave us his thoughts and professional opinions on everything inquired about.

We will definitely continue our business with Brian and the entire team at Cozy Comfort Plus.

My furnace broke mid February and from the first call Cozy Comfort Plus exceeded my expectations and it was the best customer service experience I've had in a very long time. They had someone here within two hours who very knowledgeable and gave me several options. I ended up deciding to replace my furnace and they had it done the next day. From my first contact on the phone, to the technician to the installation staff they were all professional, responsive and truly a pleasure to work with. In a little over 24 hours the heat was back on and at a very fair price.

I cannot recommend them highly enough as it's a stressful time when your furnace goes mid February. They even submitted the rebates before I had a chance to call them the next day!! All I can say is WOW.
