#1 Change your air filter regularly.
You would be surprised how many no cooling calls we run every summer to homes only
to find the only problem is that the air filter hasn’t been changed in months. “Sometimes Years”.
This imposes stress on your blower motor especially on newer units with variable speed motors.
This slows your airflow and will drastically decrease energy efficiency. It will also cause stress
on your outdoor compressor causing liquid refrigerant to wash lubricating oil from your
compressor thus reducing the life of your compressor. A compressor is like a car engine in the
way it has oil internally that lubricates moving parts and just like a car engine without that oil
neither will last long. The most common seen problem with a clogged-up air filter is the indoor
coil will freeze up which will not only completely stop air from coming out of our vents, but it
can make a huge mess when system is thawed out.
#2 Don’t blow grass clippings at your outdoor unit
Another common but preventable problem we run across is a clogged up outdoor coil.
The coil around the outdoor unit will need to be cleaned annually due to pollen dust and fall
leaves but you can rest assure that if you blow your grass when mowing at your outdoor unit
your going to have problems. With the hot summer days we have here in North Carolina a
clogged outdoor coil can cause your unit to run at two or three higher pressures than normal.
This can overheat the compressor, causing non repairable internal problems, trip high pressure
switches and at the very least raise your power bill. So when your mowing aim the other way!
#3 Clean your condensate pump
Not all cooling systems have a condensate pump but most of the time if your air handler
or furnace is located in a garage or basement there will be a small rectangular pump that pumps
the condensate your air conditioner creates to the exterior of your home. This pump never pumps
100% of the water out of it so it is a perfect place for algae to thrive. You can disconnect power
to the pump and take it apart to clean. You tube has many videos on this if you want a step by
step on how to do it. It’s not that hard and could be an easy DIY to impress your spouse. You
can also purchase algae tabs from your local hardware store and install them in your pump this
will help prevent and kill the algae to help keep your pump operating smoothly all year long. If
you purchase algae tabs, I recommend crushing the tabs up first or dissolving them in a bottle of
water before installing in your pump. I have had a whole tab in the past get stuck in the suction
hole and damage the pump, so I always crush or dissolve before installing.
#4 Clean your condensate pipe
All air condition systems create water. If your system was not equipped with a float
switch then this can create a very expensive mess especially if your air handler or coil is located
in an attic. Your air handler or coil will typically have a white PVC pipe that carries the
condensate either to the outside of your house or to a condensate pump. Just like the pump
described in #3 your pipe is a prime place for algae to build up. If you look around the outside of
your house most of the time the white pipe will be sticking out of the foundation wall close to the
ground somewhere around the exterior of the home. If you own a shop vac it’s a good idea to
suck this pipe out a couple times a year this will usually keep from causing any problems all
#5 Invest in an Energy Savings Agreement
The other four tips have been DIY and the internet is full of them to help you take care of
your HVAC system yourself. Although you can do several things on your own to help prevent
break downs and keep your system operating properly there is no replacement for a Hawley Air
Heating and Cooling trained technician with a fully stocked van who has the proper cleaning and
measuring tools to preform a precision tune up. Your HVAC system is probably the third most
expensive thing you own, it keeps you family comfortable year-round and is probably the
number one power consuming appliance at your house. You wouldn’t drive your car for long
periods of time without changing the oil so don’t expect your HVAC system to operate for long
periods of time without maintenance. A properly tuned up system can offer you years of comfort
and save you thousands of dollars over its life span.
