What’s Included in an HVAC Maintenance Check in Woodbridge, VA

Your HVAC system needs regular maintenance to prevent problems and unwanted costs. Spring is the perfect time to prepare your HVAC system for summer in Woodbridge, VA. Here’s what’s included in an HVAC maintenance check and the resulting benefits.

Changing Air Filters

Changing or cleaning the air filter in your HVAC system is an action you can do yourself. A dirty air filter lowers the energy efficiency of your unit as well as raises your monthly bills. Not only that, but a dirty air filter damages your equipment as it has to work harder to keep you comfortable.

Another benefit of changing air filters regularly is that it improves the air quality within your home. Air filters trap tobacco smoke, pollen, pet dander and other contaminants that affect your health.

Assessing General Operation

During an HVAC maintenance check, a service technician will assess the general operation of your system. This means that they will inspect the unit’s controls to make sure that it’ll start, operate and shut off when it’s supposed to. They will also make sure that the unit operates safely.

If there are any components outside the home, they will check the general condition. They will also brush away any leaves, grass or other debris that interferes with the efficiency of the unit.

Checking Electrical Components

Checking the electrical components isn’t something you want to do yourself, and you should always have a professional do it for you. Faulty electrical connections cause fires, reduce the life of the components of your unit and cause operational issues. Professional service technicians ensure that all electrical connections are secure and that the voltage and current are within acceptable parameters.

Component Cleaning

During the maintenance check, the service technician will clean the evaporator, condenser coils and adjuster blower components. A clean adjuster blower ensures that the HVAC unit has proper airflow to keep your home comfortable.

Airflow issues reduce system efficiency, which makes your unit work harder and raises your energy usage. Dirty condenser coils also make it harder to cool your home, even though the system runs longer.


Lubrication is essential for anything that has moving parts, as a lack of lubrication causes friction. This friction then causes damage to motors and other moving parts. The belts crack and dry out, fan blades break, motors wear down and you use more electricity.

Loud clicking noises will signal that your system has damage. A service technician will inspect your system for signs of damage and replace anything that’s broken.

Refrigerant Check

The refrigerant in your HVAC system cools and dehumidifies your indoor air. It’s located inside the coils of your air conditioner. If your refrigerant is too low, this causes your system to become dry, which damages the compressor and reduces the life of your unit while decreasing energy efficiency. A licensed service technician will check your refrigerant levels, inspect it for any leaks and refill the system as needed.

Thermostat Setting Inspection

Your thermostat is an important element in your HVAC system. When you set the temperature on your thermostat, you expect the settings to ensure that your home remains a comfortable space and conserves power when nobody is home. Part of the inspection you can do yourself, but other parts of the thermostat inspection will require a service technician.

Make sure that your thermostat is on the proper setting you need. In the Woodbridge, VA, area, the temperature fluctuates greatly during the springtime, and you may find yourself needing both heating and cooling in the middle of spring.

We know that how important it is to maintain a comfortable temperature within your home. This is why we ensure that each customer receives fast and reliable service. Contact Brennan’s Heating & Air Conditioning today for the HVAC service you need, and ask about our energy-efficient HVAC solutions.
