With temperatures still in the 80’s, it’s easy to forget that fall is just around the corner. As the season changes, so do the demands on your heating, ventilation and air conditioning system. Instead of running the AC, homeowners will be looking to their furnaces and other heating systems to keep their homes comfortable.

As a result, many homeowners are scheduling their end of summer HVAC maintenance, and it’s easy to see why. End of summer maintenance gives you the chance to address any lingering AC issues, and to make sure your heating system is ready to handle the cooler weather that is right around the corner.

Check out these end of summer HVAC tips for the end of summer that will keep your system running more efficiently, last longer and reduce overall maintenance costs.

End Of Summer HVAC Tip #1: Your Condenser Needs Its Space

First of all, take a look at the area around your outdoor unit. Is it clear of yard waste and other debris that could block the air flow? If so, make sure to clear about three feet of space on all sides of your outdoor unit. This will make sure your unit has the appropriate airflow and prevent damage from debris getting into the system.   

End of Summer HVAC Tip #2: Look And Listen

The fancy way of saying it is “visual inspection,” but we’re just going to suggest that you go look at your AC unit. While you’re out there clearing three feet of space around the AC, give it a once-over and check it for damage, especially from lawn care equipment, fallen branches or your neighbor’s dog.  

After checking the AC for visible damage, listen to it run. If the system is louder than usual, or you hear a new noise or anything that seems out of the ordinary, call an experienced HVAC technician to diagnose and address the problem.

End Of Summer HVAC Tip #3: Replace The Air Filter

How many times have you changed your air filter since you started using the AC? In Coeur d’Alene and Spokane, we are entering our fourth month of summer temps which means you should have replaced between one and three filters. If you are shaking your head “no”, then it is definitely time to change the filter to avoid damaging the unit.

Changing your filter allows your HVAC system to draw more air with less effort. A system that has to “breathe” through a clogged filter has to work a lot harder than a system with a clean filter. A new filter means your HVAC system will be more efficient, your indoor air cleaner and lower bills.

End Of Summer HVAC Tip #4: Check For Leaks

During your visual inspection, look for leaks from any part of your HVAC system. Leaks can indicate a number of serious problems with your system, from a clogged condensate line to dirty condenser coils. While it’s expected for an AC unit to drain off a small amount of condensation, anything greater than normal can be a clue as to the specific problem with your system.

End Of Summer HVAC Tip #5: Prepare For Winter With A Furnace Tune-Up

The best way to ensure that your furnace or heat pump will heat your home when you need it most is to schedule a furnace tune-up. Preventative furnace maintenance is one of the best ways to minimize your energy bill and ensure that your family is comfortable in fall and winter.

Not only that but keeping your gas furnace properly maintained can reduce the threat posed by carbon monoxide. Known as the silent killer, this hard to detect gas is responsible for over 400 deaths every year. During your annual furnace maintenance, the technician will check the gas-air ratio and ensure that the exhaust flue is venting this dangerous gas.


Your air conditioner or heat pump keeps you cool in the summer and your heat pump or furnace keeps you warm in the winter. To ensure that your system can do both, it’s important to take care of your system and these end of summer HVAC maintenance tips are the first step.  Call Trademark Mechanical Heating & Air Conditioning today at (208) 772-5269 to schedule an HVAC tune-up and keep your family comfortable and your energy bills down.
