Customer Reviews:
Zahra was our technician today and she was wonderful! She made sure that our toilet shut off that snapped in half was not only fixed, but adjusted it to avoid future problems AND made it look pretty. The copper line was way shorter before- she went above and beyond just fixing it. Thank you!
The technician Rob was excellent. He was personable, knowledgeable, and very courteous throughout the entire appointment. He took the time to explain everything thoroughly and made sure we understood our options and the work being done. Overall a great experience and very reassuring service. Highly recommend!

Customer Reviews:
Woke up the other day to a cooler than normal house….. not good.
Saw my furnace struggling to start. I’ve seen Boonstra trucks in my area so thought I’d give them a call.
Long story short, they got a tech out to my house in a timely manner. My tech, Dylan R. was very friendly and profeesional. He quickly diagnosed the problem and had my furnace back up and running in no time. He stayed for a bit just to make sure it was all good, while also checking for carbon monoxide and gas leaks. Very thorough.
Overall my experience with Boonstra is a very positive one, fast friendly service at a reasonable price . Give them a try!
Just had our first year maintenance checkup on our furnace and water heater. Luke was very informative regarding filters and other accessories. He was very thorough and very easy to talk to. We have always been happy with the service we received from Boonstra. Thanks so much and we’ll be scheduling a visit in the spring for our air conditioning unit.

Customer Reviews:
I cannot say enough good things about Shipton’s service. I had an issue with my furnace and Eddie, who was incredibly accommodating, had a service technician to our home promptly. The service technician, Kyle, was the absolute best. Showed up at the time identified, walked me through the process, diagnosed the issue and was equipped with all the necessary equipment to fix the issue. Kyle was also incredibly professional and respectful. I highly recommend Shipton’s as well as Kyle.
We’ve been using Shipton’s for the maintenance of our 18 year old ultra high efficiency furnace for years. And have always been pleased with honesty of the techs.
When it became apparent that it was end of life for the old furnace, we immediately reached out to Shipton’s yet again.
The entire process from the explanation of our options (highbred gas/heat pump) to the installation was again as we’ve been accustom to. Fast, friendly and as always professional. I especially appreciated the patience our installers had explaining the new equipment operations to this old guy. 👍👍👍

Customer Reviews:
Dynamic did a great job replacing our furnace and ac unit. The consultant was fantastic and worked with us to find the system that worked for us. The installers were also amazing; they were courteous, professional, and they did a superb job. The installed machine looks great and all the lines and piping is routed and anchored securely out of the way; its 100x better than the installation of the original equipment and you can tell that these guys take pride in their work.
Absolutely earned their five star rating and I am only too happy to add to it.
When you are always cold even when the furnace does work, you are vulnerable when it quits unexpectedly. This company provides timely professional service, made no attempt to unnecessarily upsell, all at a price point I was happy with. Thank you!

We had an issue with our furnace, our HVAC technician Nathan P. did a great job to make sure we were taken care of.

How to Choose the Best Furnace Repair Company in Hamilton
A broken furnace isn’t just an inconvenience—it’s an emergency that needs quick, professional attention. With so many options in Hamilton, picking the right heating contractor can mean the difference between a quick fix and costly repeat visits.

Emergency Response Time
Look for companies that guarantee same-day service, especially during winter months. The best contractors have 24/7 dispatch and can provide realistic arrival windows, not just vague promises.

Frequently Asked Questions
How much does furnace repair cost in Hamilton?
Furnace repair costs in Hamilton typically range from $150-$800 depending on the issue. Simple fixes like thermostat problems or filter replacements cost less, while major repairs like heat exchanger or blower motor replacement can run $400-$800. Most reputable companies offer upfront pricing and free estimates, so you’ll know the cost before any work begins.
How do I know if I need furnace repair or replacement?
Generally, if your furnace is over 15 years old and repair costs exceed 50% of a new unit’s price, replacement makes more sense. Warning signs include frequent breakdowns, yellow flame instead of blue, strange noises, uneven heating, or dramatically increased energy bills. A qualified technician can assess your system’s condition and recommend the most cost-effective solution.
What should I expect during a furnace repair service call?
A professional service call starts with system diagnosis and safety checks, including testing gas connections and electrical components. The technician should explain the problem clearly, provide upfront pricing for repairs, and show you any damaged parts. Quality companies like those in our Hamilton ranking typically complete most repairs in 1-3 hours and offer warranties on their work.
