HVAC systems can last over a decade, but to last that long, they need to be maintained. It’s important to have an HVAC repair company perform regular inspections, tune ups and maintenance, but there are some tasks you can do yourself, especially if you’re handy. Learn about some of the AC maintenance steps that any homeowner can do.
Changing Your Air Filter
The air filter is your AC system’s first line of defense against the elements that make their way into your home. They should be changed every 90 days, more often if you have pets or allergies. Fortunately, this task is fairly easy for homeowners or renters to do on their own.
First, you need to measure your unit to find the right size for your air filter. You can do this by removing the current air filter and checking the cardboard around the filter for measurements. On a central air conditioner, you should be able to find the main unit easily. When you do, unhook the latch on the cover grille to remove the filter. If your system has an air handler cabinet, this is typically even easier.
Then, buy the properly-sized filter at a home improvement store or a department store. After you bring the filter home, installing it is as easy as taking out the old one, cleaning the surrounding area with a microfiber cloth, and securing the latch. You can even clean the slats using a vacuum cleaner with a brush attachment. This is an easy task that most people can do, but there is even more DIY maintenance you can do as a homeowner if you’re a little more handy.
Cleaning the Condenser and Compressor
Every once in a while, the outside air conditioning unit needs to be cleaned to run efficiently. This is something you can do every few months as needed. Start by cutting off power to the air conditioner condenser so you don’t risk electrocution. Then, clean debris from inside the unit and about a 2 foot radius round the unit.
When the debris is out of the way, you can start cleaning the air conditioner fins and the condenser fan. This may require tools like a hard paint brushes and kitchen knives to accomplish, depending on how stuck on the dirt is. If the fins are removable, consider spraying them down with a garden hose. This will remove most stuck on dirt.
Cleaning the Evaporator and Blower
Once you’ve cleaned the outdoor unit, you can move indoors to clean the internal HVAC system. This is a slightly less involved process, as you’re only dealing with indoor debris and, ideally, less humid air conditions.
The evaporator has two main parts that need to be cleaned, the coil and the drain. To clean the coil, use a soft brush to remove dust, then spray with a no-rinse coil cleaner or a mild detergent mixed with water. The drain can be cleaned with a wet/dry vacuum cleaner. Look for an inch-wide PVC pipe either outside near the condenser unit or inside near a sink or utility drain.
When to Call the Pros
The items listed above are basic needs for your HVAC system. Some tasks, like in-depth duct cleaning and annual maintenance, should be left to the professionals. Getting too deep into your HVAC system can be dangerous, which is why trained professionals should be the ones doing the more complex inspections and maintenance.
