HVAC Spring Maintenance

May 18, 2016

Your home’s heating and cooling system, or HVAC system, is more likely to run smoothly and efficiently if regular maintenance is performed.  It’s proven that regular maintenance can prevent repairs and costly fixes.   Now that we are finally shaking off winter here in Seattle and heading into summer, this is the perfect time to attend to your HVAC maintenance.  Our Seattle HVAC technicians are available to help you get your home’s heating and cooling system ship shape.   

Read here for our spring HVAC maintenance checklist:

It’s no secret that HVAC systems operate more efficiently and are less likely to experience equipment trouble, such as unwanted repairs, if they are properly maintained.  Care and regular maintenance of your home’s heating and cooling system can ensure that your home and family are comfortable throughout the year.  And, a well maintained HVAC system will, ultimately, save you money.  

Here is the recommended HVAC maintenance check-up according to EnergyStar, the EPA program dedicated to energy efficiency.  

  • Check thermostat settings to ensure the cooling and heating system keeps you comfortable when you are home and saves energy while you are away.
  • Tighten all electrical connections and measure voltage and current on motors. Faulty electrical connections can cause unsafe operation of your system and reduce the life of major components.
  • Lubricate all moving parts. Parts that lack lubrication cause friction in motors and increases the amount of electricity you use.
  • Check and inspect the condensate drain in your central air conditioner, furnace and/or heat pump (when in cooling mode). A plugged drain can cause water damage in the house and affect indoor humidity levels.
  • Check controls of the system to ensure proper and safe operation. Check the starting cycle of the equipment to assure the system starts, operates, and shuts off properly.

For spring HVAC maintenance, these things are specific for the cooling function of your system: 

  • Clean evaporator and condenser air conditioning coils. Dirty coils reduce the system's ability to cool your home and cause the system to run longer, increasing energy costs and reducing the life of the equipment.
  • Check your central air conditioner's refrigerant level and adjust if necessary. Too much or too little refrigerant will make your system less efficient increasing energy costs and reducing the life of the equipment.
  • Clean and adjust blower components to provide proper system airflow for greater comfort levels. Airflow problems can reduce your system's efficiency by up to 15 percent.

Also, here are things you should do on a monthly basis to keep your HVAC in good working order. 

  • Inspect, clean, or change air filters once a month in your central air conditioner, furnace, and/or heat pump. If you are unsure how to do this, your contractor can show you. A dirty filter, which is an easy thing to change, can increase energy costs and damage your equipment, leading to early failure.
