It is not usual for a furnace to make loud noises. So, when this starts happening in your home, it can be both irritating and frightening. There could be a variety of causes, ranging from something as straightforward as a dirty air filter to more complicated problems like ductwork problems or age-related deterioration. A clogged or dirty air filter may trigger your furnace to work harder than required, leading to noise. Loose or worn-out components, on the other hand, can cause creaking or banging noises. Furthermore, ductwork issues, such as leaks or obstructions, can cause your furnace to generate loud sounds as well.

 A dirty or malfunctioning pilot light could be the cause of your furnace’s persistent humming noise. Finally, if your furnace is over 15 years old, it may begin to make more noise due to age-related wear and tear, and you might want to replace it with an updated and better-performing model.

Regardless, to avoid further damage to your unit, the best thing you can do is reach out to a professional HVAC company in your area to have your furnace inspected and repaired as soon as possible As such, if this is something you are currently dealing with, don’t hesitate to reach out to the team at Oosterveld Heating & Air Conditioning in Guelph, Ontario for assistance!

When your furnace isn’t working correctly, and you’re getting cold air instead of warmth, it can be very annoying. Below are some things to look into:

 To begin, ensure that your thermostat is set to “heat” and that the ambient temperature is greater than the present temperature in the room. It’s a straightforward step that’s all too easy to overlook! Next, ensure that your furnace is powered on and turned on. Check the circuit breaker for electric furnaces. Check that the gas valve is open and the pilot light is lit in the gas furnaces. If none of these things are the problem, a clogged air filter may be hindering warm air from flowing throughout your home.

If your home has a gas furnace and the pilot light isn’t lit or is dirty, your furnace may be unable to produce warm air. To resolve the issue, a technician can clean or substitute the pilot light. In any case, it is critical to address the problem as soon as possible in order to keep your home cozy and warm while preventing further damage to your heating system.

As such, if this is something you are dealing with in your home, reach out to the team at Oosterveld Heating & Air Conditioning to schedule your repair appointment with a certified HVAC technician in Guelph, Ontario, today!

Water leaking from your furnace can be alarming, and it’s critical to address the problem as soon as possible to avoid any damage or safety risks. There are several potential reasons for your furnace leaking water, and it’s critical to have a certified HVAC technician inspect it to properly diagnose the problem.

 Condensation is one possible cause. Condensation is produced by high-efficiency furnaces as part of the heating procedure, and it is usually gathered in a drain pan and emptied away. If the drain line becomes clogged, water may back up and leak from the furnace.

Furthermore, a clogged or dirty air filter may additionally cause the furnace to overheat and shut down, resulting in water leaking from the unit. At the same time, a cracked heat exchanger is another possibility. This is a serious problem that can result in carbon monoxide spills and other safety hazards for you and your family. Therefore, you need to immediately shut off all power to your furnace and exit your home before calling an HVAC company and local gas company to come to inspect your home.

Is your home’s furnace system leaking? If the answer is yes, please do not hesitate to reach out to the team at Oosterveld Heating & Air Conditioning as soon as possible. Our certified HVAC technicians are available to you 24/7/365, including holidays and weekends, at no extra charge. We’ll make sure that your furnace is back up and functioning safely for you and your family in no time so you can get back to enjoying the comfort of your home with as minimal disruptions as possible.

What Homeowners Say About Us

I was very impressed with Oosterveld Heating and AC and would definitely recommend them. Phil came right away and provided an excellent quote for the combination boiler hot water tank for my 1948 home with radiators. The install team was excellent and did not leave a mess behind. I am very pleased with the system and how efficiently it runs. The girls in the office are very friendly and followed up after the install to make sure I was a satisfied customer.”​
