Everything You Need to Know About HVAC Maintenance

Regular maintenance is a great way to ensure that an HVAC system continues to run efficiently. Efficiency leads to saving money in both the short and long run. When your HVAC unit in your Wilmington, NC, home operates properly, it is less likely to break down at an inconvenient time or need frequent, costly repairs.

Clogged Air Filter

We encourage our customers and their neighbors to schedule regular maintenance so they can prevent unnecessary issues during their unit’s life span. A productive HVAC system begins with a clean air filter. The filter traps all the particles in the air, so it’s going to build up a visible layer of dust over time.

Over time, an air filter that traps dust and other particulates from the air will become clogged if not changed at regular intervals. The airflow becomes impacted, which can result in the unit overheating and an increase in your energy bills.

Replacing the air filter is one of the first tasks our technician will complete. It is also one of the most important.

Clogged Drain

Clogged drains lead to leaks. Clogged drains also indicate that there is a problem occurring inside the unit. When we come out to service your HVAC unit, we’ll inspect and clean your drain line.

A clean drain line means that your carpet and flooring remain intact because there is no moisture spilling onto it. It also means that it is not flooding, which is a good thing. When there is an absence of leaks, there’s usually an absence of bacteria on your flooring.


If your HVAC unit is leaking, a clogged drain could be the problem. It could also be erosion of the metal parts due to the corrosion. It is not uncommon for the coils to corrode due the refrigerant.

Once a leak begins, it is not going to stop until the part is replaced or repaired. Regular maintenance prevents leaks from occurring prematurely, which saves you money on the repair or replacement part.

Clogged Vents

Clogged vents also have an impact on airflow and output. More importantly, it is an easy fix. Our technician cleans the outside and inside of the unit thoroughly.

To prevent clogged vents, our team takes the time to remove debris on the outside of the unit and around it. Then, the service technician takes the time to clean the inside of the unit. In order to prevent hot spots while the unit is operating, the vents have to be clear of debris.

Poor Output

Poor output from an HVAC system can be the result of many issues. It could be a dirty air filter, a clogged vent or dirty parts. Poor output could also be the result of a faulty thermostat.

Today, smart thermostats are included in the newest HVAC models. A smart thermostat can also be purchased and installed on an existing model. There are several advantages that come with a smart thermostat.

Mainly, a smart thermostat allows you to set up your preferences and settings. Smart thermostats also let you track your program and energy usage, so you can adjust your settings accordingly to reach your desired comfort and spending levels.

Higher Energy Bills

If you notice that your energy bills are increasing even though your provider has not raised the rates, it could be that your HVAC unit is in need of maintenance. Often, it simply means that you are running the unit longer because you are not getting the result you desire. It could also mean that the parts are working harder than necessary because the components are loose, dirty or old.
