What Homeowners Say About Mr. Furnace’s HVAC Services





“From the home comfort specialist to the installers, Mr. Furnace was a pleasure to deal with and very accommodating. They went above and beyond from initial consultation to the end of installation. They committed to everything they said they would do and more. All work is certified and looks very clean and neat. They are even coming back in the spring for AC unit start up. If you need a new furnace, air conditioner, or just service I highly recommend Mr. Furnace.“





“I have had the best quality service, maintenance and assurance of safety and performance of the furnace and humidifier unit! Matt and others have been professional and explained the issues of concern. This was a scheduled annual maintenance and some problems needed tending to proactively rather than waiting for the system to break down. I am so glad I joined the monthly program. A superb company and team!“





“Starting with Salesperson Mike, and ending with tech installation team, Gareth and Lucas, the entire project was seamless. No pressure sale with genuine care and expert advice, offering next day install at a fair price. Promptly on Sunday morning, Gareth and Lucas showed up, and didn’t stop until the install was complete. Friendly, knowledgeable, considerate and professional, all attributes indicative of Boonstra. System works great and I am extremely pleased with the service, price and overall experience.“
