If you’ve discovered that your furnace is turned on, but your house is still cold, there might be a few explanations for this. A dirty air filter is a frequent culprit, as it can restrict airflow, making it difficult for your furnace to warm your residence correctly. If that’s the case, you will need to replace or clean the air filter to ensure the airflow is optimal.

 Another potential problem is that your thermostat is malfunctioning. If your thermostat isn’t working correctly, it may not be conveying the correct information to your furnace, causing it to run without creating sufficient heat. In some instances, checking the thermostat settings and ensuring that it is set to “heat” mode can resolve the problem. However, if your furnace is in its “heat” setting, you may want to call a repair technician to come to take a look!

Furthermore, if neither of these seems to be the case, the reason could be more technical, such as a problem with the furnace’s ignition system or blower motor. All of these components would be required for a professional HVAC technician to perform a diagnosis and repair.

We understand that it can be concerning if you detect water pooling around your furnace while your air conditioner is operating. There are several possible explanations for this, but here are some of the most common:

1. An obstructed drain line: When your air conditioner runs, it produces condensation, which is typically emptied away through a condensate drain line. If the tube gets blocked, the water may back up and overflow, causing it to leak around your furnace.

2. A condensate pump that isn’t working: If your air conditioner is in an area with limited drainage, it might depend on a pump to eliminate water. If the pump fails to function properly, water can build up and leak around the furnace.

3. Frozen evaporator coil: A frozen evaporator coil may cause water to overflow and leak near your furnace. This could be due to low refrigerant levels or constrained airflow.

Our competent and knowledgeable HVAC technicians are available 24 hours a day, 365 days a year, including after-hours, weekends, and holidays with no additional service fee!

Furnaces, like every other device, contain multiple components that can wear out and cause the system to fail over time. The igniter, blower motor, limit switch, flame sensor, and control board are some of the most common furnace parts that can fall short. This is why it’s crucial that homeowners aim to have their heating system professionally serviced by a certified HVAC technician at least once a year. Not only is this going to save you more money on costly repairs over time, but it’s also going to extend the lifespan of your equipment while providing you peace of mind.

 So, when was the last time you had your home’s furnace equipment serviced by a certified HVAC technician? If you can’t remember, or it’s been well over a year, we recommend reaching out to the team at Oosterveld Heating & Air Conditioning for assistance! Our skilled and knowledgeable HVAC technicians are available 24 hours a day, 365 days a year, including after-hours, weekends, and holidays, at no extra charge!

If your furnace breaks down, there are certainly a couple of things you can try before calling a professional HVAC technician so you can have a better idea about what you may be dealing with. Here are a few troubleshooting steps you can take:

1. Examine the Thermostat: Ensure that your thermostat is set to heat and that the desired temperature is set above the present room temperature. If the thermostat’s batteries are dead, switch them to new ones.

2. Look at the Air Filter: A clogged air filter can limit airflow and prompt your furnace to stop working. If your air filter is dirty or clogged, call an HVAC company to come and replace it!

3. Examine the Power Supply: Ensure that your furnace is receiving power. Check your electrical panel and fuse box to ensure that all switches are on.

4. Look at the Gas Supply: If you have a gas furnace, ensure that the gas valve is open and the pilot light is turned on.

If you’ve examined all of these components and your furnace is still not working, you should contact a professional HVAC technician. They can diagnose the problem and perform whatever repairs are needed to get your furnace back up and running. It is always best to leave furnace repairs to the professionals who have the expertise and equipment necessary to solve the issue effectively and safely.

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.”​
