Spring Cleaning Your HVAC System 

It's been a long, hard winter for your HVAC system. These spring-cleaning tips can help take the dust off your system and improve operating efficiency.

Spring cleaning has long been an annual ritual in millions of households across the country. As the season changes, now is the perfect time to shake the dust off your HVAC system, helping it run more efficiently and saving you money this summer and all year long. 

Here are some spring-cleaning tips for your system. 

Lubricate moving parts:

Your HVAC system contains a lot of moving parts such as fans and motor bearings. The constant movement creates a great deal of friction. Over time, this friction can cause moving parts to deteriorate and finally fail, possibly damaging your entire system and leading to expensive repairs. It's important to lubricate HVAC system parts at least twice a year. As you're gearing up for the summer cooling system, spring is the perfect time to do this. 

Clear debris from outdoor units:

Leaves, sticks and other debris on outdoor condenser units can block your vents, which can reduce air flow and system efficiency. It's important to clean the area around your condenser units and other outdoor components of this type of debris. Also, dirt and small debris can make its way inside the unit. Cleaning these involves taking the unit apart and reassembling it, which should be done by a qualified HVAC technician. 

Clean indoor components:

Indoor components — such as blower fans, evaporator coils, ductwork and vents — are also subject to dust and dirt accumulation. Dirty components are less effective at moving air, which reduces system efficiency and increases operating costs. That dirt and dust can also make its way into your residence, reducing indoor air quality. Make sure your system is thoroughly cleaned by a qualified technician. 

Clear condensate drain lines:

Condensate drain lines remove the excess moisture that can build up in your system. When drain lines get clogged, mold and bacteria can grow inside the system and then spread throughout your house. Check condensate drain lines for obstructions and make sure any excess water can flow freely. Consider applying an algaecide to prevent algae growth that could block drain lines. 

Change air filters:

Air filters catch dust and other particles before they enter your residence, keeping the air clean and safe to breathe. When these filters get blocked, allergens such as pollen can enter your building. Dirty filters can also impact the performance of your HVAC system. Install fresh air filters throughout your system and change them regularly according to the manufacturer’s guidelines. 

To optimize efficiency and comfort, have your HVAC system cleaned and inspected twice a year by a qualified professional, and be sure to practice preventive maintenance regularly.
