HVAC Essentials: Late Summer And Fall Maintenance Tips

During the dog days of summer, little is worse than having your HVAC system go out. Unless it also happens to include diagnosing and repairing your system when the temperature outside begins to climb.

To prevent a critical failure of your HVAC system at the absolute worst time possible, it is important to perform regular maintenance. Here, we will discuss some easy ways that you can keep your system running smoothly and consistently.

Keep your condenser unit fan cleared of debris

Over time, dirt, grass, and other debris will begin to accumulate on the outside condenser unit. This causes the system to work harder to compensate for the blockage, which in turn puts a strain on your HVAC system and your energy costs.

Remove what debris you can by hand along with any nearby vegetation or branches. Most newer condensers can be safely washed off with a hose once powered down, so make sure that yours can before doing so.

Regularly check your HVAC system’s wiring

There are certain signs to look for that can either be a precursor for system failure or a blatant example of one, including:

  • Bulging wires
  • Blackened or burned wires
  • Scorch marks

If you notice any of these items in or around the access panel, do not attempt to repair it yourself. Call a professional right away.

Replace your cooling system’s air filter before summer begins

Depending on where you live and your own personal comfort level, your cooling system may work harder than someone who lives in, say, Antarctica. To reduce the amount of pollutants making their way inside and to keep your system running efficiently, it’s important to replace your air filter regularly.

Those in more temperate environments may not give their cooling system air filter much thought until it’s time to use it, but it’s always a good idea to replace it before summer begins, and every 1-2 months during.

Consider upgrading your HVAC system

Most modern HVAC systems come with a programmable thermostat that keeps your home at a consistent temperature, turning on the cooling and heating as needed. Newer programmable thermostats are equipped with Wi-Fi and can be accessed remotely.

Another great way to reduce cooling costs is to use fresh outside air as needed. Products like our zip economizer make the process of switching between mechanical cooling and fresh air easier (ex: switching from mechanical cooling during the day to fresh air cooling at night when it’s much cooler,) which can greatly reduce energy consumption.

Install the zip economizer and how it can help you reduce energy costs.
