What Happens When You Don’t Maintain Your HVAC System?

HVAC maintenance

At Oliver, we’re always telling our customers how important HVAC maintenance is. A reliable HVAC maintenance plan can keep your unit running smoothly, improve its reliability, and extend its lifespan. Some of our service calls are made because the HVAC unit hasn’t been properly maintained. Here are some things that could happen when you don’t have a maintenance plan:

Improperly Functioning Thermostat

When your thermostat doesn’t function properly, your HVAC unit may not turn on when it’s supposed to or turn off when it’s supposed to. Not only is this bad for the unit, but it also affects the comfort of you and your family.

Dirty Coils

Your HVAC unit’s evaporator coil is located on your indoor unit and works much like a radiator to make sure that the air flowing through your ductwork is heated or cooled properly. A dirty evaporator coil can restrict airflow, which can also dramatically reduce your unit’s efficiency. The dirt can also harbor mold and mildew, giving your indoor air poor quality.

During the summer, your outside HVAC unit’s condenser coil is responsible for eliminating the hot air that is sent to it. The cleaner the coil, the more efficiently it can handle the hot air. If your condenser coil is dirty, your unit’s efficiency can dramatically drop, hiking up your energy bills and reducing the unit’s lifespan.

Dirty Filter

The role of an HVAC air filter is to filter out pollen, allergens, dander, and other airborne particles that can harm your health. A good air filter will give you high-quality indoor air that can not only prevent illnesses but also shorten them. When your air filter is dirty, airborne particles aren’t filtered; instead, they enter your home through your ductwork and are breathed in by you and your family.

Blocked Condenser

Your condenser is one of the most important parts of your HVAC unit. It’s responsible for desuperheating, condensing, and subcooling to make sure the air that flows through your home is the right temperature. A blocked condenser means the heat transfer that usually occurs won’t be able to take place and the condenser’s temperature will rise. When this happens, your HVAC unit won’t operate efficiently and if not taken care of, your condenser could burn out.

Leaks

Leaks in an HVAC unit can be caused by several common scenarios: the drain hole is blocked with dirt or debris, the condenser pump is broken, the seals on your unit aren’t tight, or your hose is clogged or blocked. All of these things can occur if you don’t properly maintain your HVAC unit.

Power Malfunctions

As part of our maintenance plan, we’ll perform an annual 21-point inspection where we’ll make sure that your HVAC unit can power up properly and power down properly. If it can’t, you’ll run into a lot of frustration when your home is too warm or too cool and you can’t run your unit properly in order to adjust the thermostat.

Dirty Blower

The role of your HVAC’s blower is to circulate the warm or cool air throughout your home. When it gets dirty, it requires more energy to operate, which increases your energy bills. If a blower gets dirty enough, it will fail and once it fails, it’s a sign that more problems are to come. If this happens, many HVAC companies recommend replacing your entire HVAC system.
