Furnace Troubleshooting Checklist
If you experience an issue with your furnace, you can call HAMCO. However, sometimes the solution is simple and something you can do yourself.
Before you call for emergency service, troubleshoot your furnace using this checklist.
- Ensure your thermostat has new batteries.
- Check that your thermostat is on and set to HEAT.
- Inspect your furnace filter and replace it if necessary.
- Confirm that the furnace is on and getting power.
- Look to see if a breaker has been tripped.
- Make sure all air vents are open and not obstructed.
- Remove any snow or debris blocking the exterior intake and exhaust pipes.
Please don’t ever try to repair your furnace by yourself. If none of these solutions work, call HAMCO and one of our certified technicians will diagnose and repair your furnace.

Update: We just had our annual maintenance done and as usual, the booking and service were done efficiently and professionally. Cameron was pleasant and before servicing the... furnace and AC he was happy to answer a couple questions I had. Pleased once again with Hamco's service.We were recently faced with our 17-year-old furnace breaking down and beyond repair. Despite the extremely cold weather that resulted in a larger number of service needs for Hamco, Najim met with us in just over 24 hours, spent time accessing and explaining the situation and offering the best options for the needed replacement. He worked to get us up and running quickly with a Saturday install and left us with a space heater to ease discomfort overnight. He was personable, knowledgeable and took time to ensure we were happy with the decision we made. It wasn't an expense we had planned for but Najim eased the situation with his excellent customer service. He was happy to answer any questions we had and worked to ensure we got the best price and service possible. Veronika and Shemar arrived early the next day to replace our furnace with a new Daikin. They were also personable, professional and efficient. We feel fortunate to have Hamco to count on with HVAC needs. They have a great team of people who also seem to greatly appreciate how they are respected and treated by the company. It's wonderful to have a local family-owned business providing excellent service. We've been with Hamco (initial installs and service plans) for 17 years and plan to continue with them as needs arise.read more

Honest, expert advice! I asked HAMCO about adding a HEPA filter and UV light to my gas forced air furnace. Instead of selling me an expensive, unnecessary installation,... Andrew honestly advised that portable units would suit my needs much better. That level of integrity is rare. They truly care about the client over making a quick profit. Highly recommend!read more

I've been dealing with Hamco now for 26 years - on my 3rd house and have only had good experiences with Hamco. An example of how their staff go above and beyond is during the... installation of my furnace in 2006, my elderly neighbour complained about the wasps flying around her house. The furnace installers noticed where they were going in and resolved the problem.I get the air-conditioner checked annually and the technicians are always professional and knowledgeable. A special shout-out to Cameron who looked after the inspection today and explained the readings today.I would, without reservation, recommend Hamco to anyone needing heating and cooling equipment.read more

After doing a significant amount of research I contracted with HAMCO to install a heat pump to replace my aging air conditioner, and a new furnace. Andrew Vasilak handled... the transaction, and he was terrific to deal with. He was helpful, informative, and there were no high pressure sales tactics. The quote was identical to what I paid.The installation of the products was superb! Both my new heat pump and furnace were installed in one day. The four men who did the installation were on time, dependable and thorough. Since the installation the heat pump has been superb. Air quality in the house is significantly better, and the air temperature has been constant. I had one minor problem, and called HAMCO late at night on a long holiday weekend for assistance. I had a return phone call back in five minutes, a repairman out to my house the next morning, and the problem was fixed quickly. The service technician who dealt with my issue was professional, polite and responsive.HAMCO has been around since 1946. They are an established Hamilton company that offers old fashioned, high quality service at a fair price. I would not hesitate to recommend them.Update: May 12/26I just had HAMCO into perform an annual inspection of my heat pump, furnace and water heater. Christian did an amazing job! He was professional, thorough and extremely detailed. He took the time to explain what he was doing, and his answers to my questions were clear and concise.I continue to be impressed with HAMCO. They do amazing work, and it is reassuring to know you can depend upon them when necessary.read more

How Serious is a Furnace Short-Cycling?
When a furnace turns on and off repeatedly without ever reaching the desired temperature, it’s called “short-cycling”. It could be a sign of a serious problem or there could be a quick and easy fix.
If your furnace is short cycling, it could be due to one of the following:
- Restricted air flow from a dirty filter or blocked air vents
- An incorrectly installed or malfunctioning thermostat
- A furnace that’s too big or small for your home
The severity of your short-cycling furnace depends on what’s causing the problem. If it’s related to a dirty filter or obstructed air vent, it’s an easy fix. An improperly-sized system, on the other hand, will require an upgrade.
If your furnace is short cycling, schedule a furnace service call.
