Maintaining your HVAC system is essential for both comfort and energy efficiency throughout the year. While homeowners can handle some tasks, others require professional expertise to ensure your system performs at peak efficiency.
Homeowner Maintenance
Homeowner maintenance consists of tasks that you should take care of between professional annual tune-ups.
Air Filter Changes
One of the most critical tasks homeowners must do to maintain their HVAC system is regularly changing the air filter. The air filter plays a vital role in improving indoor air quality and also protects your HVAC system’s internal components by trapping airborne contaminants.
Experts recommend replacing your filter at least every three months. However, you may need to change yours out more often. For example, if you have pets, the filter may need to be changed more frequently due to pet hair and dander. Additionally, factors like high pollen levels in the spring and how often your system needs to run will affect how quickly your filter gets clogged.
To ensure optimal performance, it’s a good habit to check your air filter at least once a month. You can do this by removing the filter from its housing and holding it up to a light source. If light passes through, the filter still has some life left. If the filter appears opaque and no light passes through, it’s time for a replacement.
Additionally, make sure to replace your filter with one of the same size and thickness as the original. Using a filter that’s too small will not adequately filter the air, while one that’s too large won’t fit properly in the housing. A filter that is too thick may restrict airflow too much and cause strain on your system.
Clearing the Area Around Your Outdoor Unit
Maintaining a clear space around your outdoor condenser unit is essential for optimal HVAC performance. It relies on the free flow of air to effectively release heat, and any debris, such as leaves, dirt, or branches, can block airflow and disrupt this process. When airflow is restricted, your cooling system becomes less efficient. This can lead to overheating, increased energy consumption, and potential damage to the unit.
It’s a good practice to clear the area around the unit in early spring before the peak summer season. After this, check the unit at least once a month and after major storms to ensure the space remains clear. Additionally, inspecting the condenser unit’s metal fins for any signs of damage or bending is important. Damaged fins can affect airflow. If they need attention, contact a professional to address the issue.
Check Your Return and Supply Vents
Ensuring that your return and supply vents are clear is another aspect of homeowner maintenance. These vents are responsible for circulating air throughout your HVAC system, helping maintain an even temperature in your home. Blocked or clogged vents reduce airflow, causing your system to work harder than necessary, leading to higher energy costs or even system damage.
To maintain proper airflow, periodically check your vents for any obstructions, such as dust, furniture, rugs, or other items that may block the air from flowing freely. To clean the vent covers, use a soft cloth or vacuum them to remove dust and dirt. This simple task can improve airflow, reduce strain on your system, and enhance comfort in your home.
Professional Maintenance Service
Professional maintenance is an in-depth service for your entire HVAC system. This is where one of our technicians will use specialized tools to ensure that your system is operating as efficiently as possible. We recommend getting maintenance service for your air conditioner in the spring and heating system in the fall.
Cleaning Coils
One very important step of professional maintenance service is cleaning the coils inside your central air conditioning system. Both the evaporator coil in your indoor air handler and the condenser coil in your outdoor unit must be free from debris to allow heat to transfer in and out of the refrigerant inside of them. Our professionals will use a specialized cleaning solution to remove stuck-on grime without damaging the coils.
Calibrating Your Thermostat
A properly calibrated thermostat is critical to maintaining a comfortable indoor environment. Over time, thermostats can lose their accuracy and begin misreading temperatures, which may lead to inefficient heating or cooling. This issue can also increase energy costs.
Our technicians use specialized tools like a calibrated reference thermometer to check your thermostat’s accuracy. If discrepancies are found, they will adjust its internal sensor to ensure it accurately reflects the actual indoor temperature. This precise calibration ensures that your HVAC system operates as intended, improving efficiency and enhancing your home’s comfort.
Recharging Refrigerant
Refrigerant plays a crucial role in your HVAC system by transferring heat between indoors and outdoors. However, over time, leaks can develop in the system due to pinholes, loose connections, or worn-out connections. As the refrigerant level drops, your system becomes less efficient at regulating temperature, leading to increased energy consumption and reduced comfort.
During a maintenance visit, our technicians will conduct a thorough inspection to identify any leaks. They may use electronic leak detectors, UV dye, or pressure testing to pinpoint the source of the refrigerant loss. Once the leak is located, they will make the necessary repairs to prevent further issues. Afterward, they will check the refrigerant levels using specialized gauges and recharge the system, restoring your HVAC system’s performance.
Lubricating Moving Parts
Your HVAC system contains numerous moving components that rely on proper lubrication to function smoothly. Without sufficient lubrication, friction between metal parts increases, which can lead to wear and tear, decreased efficiency, and potential damage to the system. Over time, this excessive friction can even cause overheating or even the failure of components.
During routine maintenance, our technicians lubricate the fan, motor bearings, and blower components to minimize friction and ensure smooth operation. They use specially formulated lube for each part to maintain optimal performance and extend the lifespan of your HVAC system. Proper lubrication also helps reduce noise, keeping your system running quietly.
Testing for Exhaust Fumes
If your heating system burns fuel to generate heat, it will inevitably produce exhaust fumes. Under normal circumstances, these fumes are safely vented outdoors. However, if there is a malfunction in the venting system, these toxic fumes can build up inside your home, posing serious health risks to you and your family.
Our technicians will test your system during routine maintenance to ensure it’s venting correctly. If they detect escaping fumes, our technicians will first identify the source of the issue. It may be a simple fix, like clearing an exhaust pipe. However, if there is a more serious problem, such as a cracked heat exchanger, they will make a recommendation for repair or replacement.
