Spring Cleaning Your HVAC Unit

Spring Cleaning your HVAC unitSpring is around the corner and "Spring Cleaning" has become a tradition in many households throughout the country. As you open up your windows, both letting the fresh air in and dusting off everything that has been in winter hibernation, it's important not to forget your HVAC system! The weather will gradually get warmer, and when it does, you'll want your A/C unit working at its peak performance. Proper maintenance of your HVAC system ensures that your unit is running efficiently and doing its job. When this is done, you're able to maximize your use of energy which is not only good for the environment, but also good for your monthly power bills.

Steps To Take To "Spring Clean" Your HVAC System

Change Your Air Filter

We cannot stress enough the importance of a clean air filter, as you may have noticed from several of our previous blog posts (like winterizing your HVAC unit). Clean air filters keep the air in your home free from harmful pollutants that are potentially hazardous to your health and that of your family. Since all of the the air that circulates through your HVAC system eventually passes through the air filter, it's so VERY important to keep your air filters clean and change them regularly. Dirty, clogged air filters can:

  • Cause severe HVAC system malfunctions and equipment damage.
  • Reduce airflow inside the HVAC system.
  • NOT remove particulates and contaminants as effectively as they should. (These are then released back into the air that you breathe).
  • Result in duct work build up and damage.
  • Cause the HVAC equipment to work harder, increasing your energy usage and therefore your monthly electric bill.

Air filters should be checked at least a minimum of once a month and if they are dirty they should be removed and changed out for a fresh, clean air filter. A helpful tip to know if your filter is dirty or not: hold it up to a light source – if you can’t see the light through the filter, then it’s time for a new one.

Air Duct Cleaning

During the fall and winter months, as the heat passes through your HVAC system, most of the contaminants are trapped in the air filter; however, some do pass through which can lead to a build up in the duct work over a period of time. To prevent potential air flow blockages and indoor air quality problems, plus keep the temperature in your home consistent, vacuuming out the air vents is highly recommended. According to, a thorough cleaning of the air vents is recommended if the ducts are clogged with an excessive amount of dust and debris or if there is substantial visible mold growth inside hard surface (e.g., sheet metal) ducts or on other components of your heating and cooling system. If this sounds like your home, call a professional to clean your air ducts. Otherwise, a quick vacuuming may be sufficient.

Clean Standing Water By Your HVAC Unit

Moisture is one of the main requirements needed for mold to thrive and molds can grow and multiply in temperatures between 32 and 120 degrees Fahrenheit. If there are standing pools of water near your HVAC unit, the mold will grow and increase as the temperature rises and result in the moldy and musty smell to start blowing into your home. Standing water will also do swift and severe damage to whatever it touches, so its very important to get any areas cleaned up, preventing water damage to your HVAC unit and keeping the air in your home free from mold and mustiness. Here are some reasons you may find water around your HVAC unit:

  • PVC drain line is plugged
  • Filter is plugged
  • Drain pan has a leak
  • Condensation pump issues

Remove Plants And Weeds From Around Outside Unit

As spring approaches, plants and weeds start to grow and they also grow around your outside HVAC unit. Trimming back these plants is one of the easiest ways to keep your energy bills low. If plants and weeds grow too close to your HVAC unit, it can restrict air flow to your system causing higher bills and shorter equipment life. You should have at least 24 inches (or two feet) of distance between your landscaping and your air conditioning unit. This allows enough adequate air flow to the unit, keeping it cool and preventing your HVAC unit from possibly overheating. It also reduces overall electrical consumption. So be sure to add ground clearing around your AC unit to your spring cleaning list!
