Proper Maintenance – What to do and When to do it

When most homeowners think of spending money on their homes, it’s unlikely that their heating and cooling system first comes to mind. Because it’s stuck down in a corner in the basement, it’s often not thought about unless something goes wrong and it’s not working properly. Being too hot in the summer or too cold in the winter can be just the beginning of the problems, but an unmaintained HVAC system can also lead to increased utility costs and even health issues.

For the Homeowner

Due to the complex nature of a heating and cooling system, there is only so much maintenance a homeowner can personally do, but it is important to schedule yearly maintenance done by a professional.

Replacing the Furnace Filter

One of the best ways to extend the life of your furnace and to keep utility costs lower is to replace the furnace filter every three months and to do it properly. Many also don’t realize that a filter isn’t to improve the air quality in the home, but instead to prevent dirt and dust particles from impacting air flow to the furnace fan and motor. The better air flow to the furnace, the more efficiently it will work. It’s important to choose the proper filter for your system and install it the correct way – the arrows on the filter should be pointing toward the furnace.  If you’re not sure, contact your local HVAC professional.

Cleaning the Air Conditioning Condenser

Another important maintenance task for the homeowner is hosing down the air conditioner twice a year – typically spring and fall – to remove any dust, dirt and other debris such as bugs and leaves. Ensure that the power to the unit is off and use a regular hose to spray it down. It’s also important to keep the area around the condenser free of weeds or other plants or garbage.

Professional Maintenance

Having a professional come in once a year to tune-up your heating and cooling system will help your system run efficiently and can help avoid costly emergency repairs.

Air Conditioner

Late spring is often the ideal time for air conditioner maintenance since it’s important that the temperature is above 21 degrees Celsius. Any lower and it can be difficult to get an accurate reading. They will inspect the outdoor condenser, its fan and coils, refrigerant levels and other mechanical components.

Furnace

Late summer or early fall are the best times for a furnace inspection since the outside temperatures are often warm enough to not need the furnace to heat your home. Professional licenced HVAC technicians should check the following items during a tune-up:

• Gas pipes to the furnace, including a carbon monoxide test
• Chimney and flue for any debris
• Air filters for proper installation and cleanliness
• Gas pilot light and burners for safety and cleanliness
• Motor, fan and blower for cleanliness and proper operation
• Fan belts and other adjustments on older furnaces

A well maintained heating and cooling system will keep costs down, improve air quality and help you to feel comfortable in your home.
