How to Prepare Your HVAC System for Summer

Apr 16, 2021

For some locations, summer heat and humidity are already starting to take hold. It may still be cool where you are, but you will soon need your air conditioner to stay comfortable inside. High pollen levels are an issue too, as your HVAC system has a big impact on indoor air quality. It is time to get it prepared for summer, and here is how you can do this to avoid any problems during the peak cooling season.

Clean or Replace Filters

Maintaining the filters in your system is the most important thing to do. It is also the easiest and doesn’t require a service professional. Depending on the system, filters may be reusable, while some must be replaced. It’s important to clean or replace the filter in your air-handler cabinet, furnace, and return-air registers if they have filters. A filter should be cleaned/discarded whenever it looks dusty.

Each model or type of system has its own maintenance requirements. You might have to change the filter a couple of times a year, every three months, or monthly. Check the filter before summer to ensure your HVAC system is ready.

Check the Vents

Clogged, dirty vents can affect the efficiency of your AC system. Dust, pet hair, and other debris can easily block vents but can be easily wiped or vacuumed away. Proper air flow is essential; in addition to cleaning vents, make sure they are all open. Partially or completely closed vents can restrict air flow, decreasing efficiency and comfort.

Clean the Outdoor Unit

If trash, leaves, or branches have accumulated on or around the unit, remove them. These can affect ventilation and cause your system to overheat. Make sure there’s at least three feet of clearance on each side of the unit. Also examine the condenser coils for debris, which can clog them up and impede heat transfer. Some debris can even be a fire hazard. Condenser coils can be easily spray cleaned with a water hose.

Clean the Condenser

Remove any debris from around the base, clear the drain, and clean the blower fan blades. The blades can be cleaned with a rag and vacuum. If there’s water inside the unit, mop it up until dry. Lubricate the unit with WD-40 or a lightweight oil if it has lubrication ports, and tighten any mounting bolts if they’ve come loose.

Seal Air Duct Leaks

Leaky ducts can lose a third of the air that circulates in your home. That can make your home extremely uncomfortable and overwork your HVAC system. Contact an AC service company to evaluate and seal your ductwork if you suspect any problems. Also check for drafts from windows and doors and repair window stripping and door frames that have gaps. Doing so can help your AC do its job and reduce your energy bill.

Inspect All Coolant Lines

Refrigerant lines run between various HVAC components and are essential for removing heat from your home. They usually have foam insulation to prevent energy loss. Replace this insulation if it is frayed or missing, which can be done with foam insulation tape or foam insulation sleeves.

Schedule Maintenance

It’s not uncommon for dirt and debris to build up during the winter. Your AC may have developed hidden issues over the past few months, and you wouldn’t know it because the cooling system hasn’t been used in a while. That’s why it’s a good idea to schedule routine maintenance in the spring.
