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.
We were helped out by Josh and Cau the next day who did a fantastic job installing our new boiler.
Our Tech was Lucas G.and he came to service the furnace. The job was professionally done with each step explained to me while I observed him. Furnace care that could be done by me, the homeowner, to ensure proper functioning was explained also to me by Lucas.

Customer Reviews:
We got tankless and furnace service. Christian showed up on time as scheduled. He was polite, knowledgeable and quick. Offered tips and tricks for us to maintain our equipment and provided a full report for each appliances. We asked for a flush on our tankless but he advised that we were missing components to effectively do it. He offered the solution and timeline when we could do the service without causing issue to the unit.
10/10 recommend Hamco…well Christian who represents them
Will have them back again for future service and or repairs
We had a new furnace and A/C unit installed by Hamco 7 years ago. We get both units serviced annually by Hamco. The technicians have always been very friendly, courteous, and professional. This year, there was a leak in the water line leading to the humidifier on the furnace. Hamco advised me that this was not covered by the furnace warranty. Regardless, they agreed to fix the problem without charge. Derek was great and he fixed the problem quickly and efficiently.

How to Choose the Best AC Repair Service in Hamilton
When your air conditioner breaks down in the middle of a Hamilton heatwave, making the right choice quickly becomes critical. The wrong repair service can mean extended downtime, inflated costs, or recurring problems that leave you sweating through another hot night.
- ✓ Verify proper licensing and insurance coverage
- ✓ Check availability for emergency after-hours service
- ✓ Ask about upfront pricing and diagnostic fees
- ✓ Confirm warranty coverage on parts and labor
- ✓ Look for factory-trained technicians with brand certifications
- ✓ Review recent customer feedback about response times
- ✓ Ensure they service your specific AC make and model
Emergency Response Time
AC failures don’t follow business hours, especially during Hamilton’s hottest days. Look for companies offering 24/7 emergency service with clear response time commitments. Some established local companies can dispatch technicians within hours, not days.
Transparent Pricing Structure
Avoid companies that won’t discuss diagnostic fees or hourly rates upfront. Quality repair services provide clear estimates before starting work and explain what’s included. Hidden fees and surprise charges are red flags in this industry.
Technician Qualifications
Factory-trained technicians with manufacturer certifications can diagnose problems more accurately and complete repairs properly the first time. This matters especially with newer high-efficiency systems that require specialized knowledge.
Warranty Protection
Reliable repair companies back their work with solid warranties covering both parts and labor. This protection shows confidence in their repairs and gives you recourse if the same problem resurfaces shortly after service.

Frequently Asked Questions
How much does AC repair cost in Hamilton?
AC repair costs in Hamilton typically range from $150-500 for common issues like refrigerant leaks or faulty capacitors. More complex repairs involving compressors or major components can run $800-1,500. Most reputable companies charge a diagnostic fee of $80-150 that’s often applied toward repair costs. Emergency after-hours service usually adds a premium of $100-200 to the base repair cost.
How quickly can I get emergency AC repair in Hamilton?
The best Hamilton AC repair companies offer same-day emergency service, with response times typically within 2-4 hours during peak summer months. Companies like Boonstra provide 24/7 availability including weekends and holidays. During extreme heat waves, response times may extend to 6-8 hours due to high demand, so it’s worth calling multiple companies if you need faster service.
What warranty should I expect on AC repairs in Hamilton?
Quality AC repair companies in Hamilton typically offer 90-day to 1-year warranties on labor, with parts warranties varying by manufacturer (usually 1-5 years). Some local companies like Dynamic Heating provide extended 10-year warranties on specific installations. Always get warranty terms in writing and ask what’s covered — labor, parts, or both. Avoid companies that don’t offer any warranty protection on their repair work.
