When the season transitions to the colder months, it’s important to maintain your heating, ventilation and air conditioning system.

Just as you want your HVAC system to keep you cool during the summer, you’ll need to make sure your unit is ready to heat your home during the winter, too.

A combination of the following do-it-yourself and professional maintenance tasks will ensure the system is ready for any season. Read on to learn more.

Remove Unwanted Moisture

Condensation can lead to unwanted moisture on your HVAC system’s ducts, coils, drain lines, and pans in the summer, especially if you live in a humid area.

If this moisture isn’t removed, it can lead to the growth of mold and mildew, not to mention damage to your home’s A/C unit. If left uncleaned, it can even lead to sickness from airborne bacteria.

To combat this:

Monitor Refrigerant Levels

Your A/C unit has probably been working overtime during the summer, so it might be low on refrigerant.

This chemical changes from liquid to gas and back to liquid inside your A/C to cool your home. If you’re low on refrigerant, your unit will only circulate warm air.

Having the right amount of refrigerant makes air from your vents colder, reduces energy bills and makes your AC work better.

Call an HVAC professional, like an American Standard Customer Care specialist, to check it at the end of the season so you won’t be in for a rude awakening when summer rolls around next year.

Seal Any Leaks

As the heat of summer wears off, go into the attic and check your ductwork for leaks.

Feel along the ducts for air leaks while your air conditioner is running. Also, look for discolored insulation or rusty ducts that could indicate a leak.

Pay particular attention to the joints in pipes and where runs of ducts meet in case a pipe has become disconnected.

Repair any leaks using duct mastic or metallic duct tape rather than standard cloth tape. You can also have an HVAC professional run a pressurized test of the system to check for leaks.

Change Air Filter

Your HVAC system’s air filter needs to be changed about every 30 to 90 days, so the start of fall is the perfect time to do it.

Regularly changing the air filter is critical for its longevity, but it also helps your system work more efficiently. The purpose of the air filter is to trap unwanted allergens, dust and particles and prevent them from getting into the air you breathe in your home, so when the filter is dirty, your air will also become dirty.

Changing the filter on your air cleaner may also help save on energy costs.

Prepare Your HVAC Unit for the Cold Season

Now that your A/C unit is ready for next summer, take these steps to ensure you stay warm during cooler months:

When in Doubt, Call an HVAC Tech

A trained professional should inspect your home’s heating and cooling systems at least once a year. HVAC technicians have a much deeper understanding of these systems’ inner workings than the typical DIY homeowner. 

Homeowners can do minor A/C unit maintenance, but only HVAC technicians can run tests and check for poisonous gases, such as carbon monoxide, inside a home.
