Not only will a clean, well-maintained HVAC system operate more efficiently, but it is also less likely to need repairs and will have a longer lifespan. Keep your heating and cooling system in great condition using these basic HVAC maintenance strategies.
Hire a Professional for Annual HVAC Maintenance
An HVAC professional is qualified to inspect your system and make sure it’s working efficiently. The technician will inspect the ductwork, vents, and unit for cleanliness and signs of damage. All components of the HVAC system will be checked to ensure safe operating conditions.
Cleaning and minor repairs can also be completed at the time of the check-up. If larger repairs or major cleaning is warranted, the technician will make a follow-up appointment to complete the maintenance and handle any needed repairs.
Perform Routine HVAC Maintenance
Some HVAC maintenance tasks do not necessarily require a professional. For example, once a year, the air conditioning condensation line should be cleaned with bleach.
Problems that lead to inefficiency in HVAC units can sometimes be fixed without professional help, like replacing a damaged or worn-out fan belt. If you don’t feel confident performing these tasks, hiring a qualified HVAC technician is always an option.
Safety and Your HVAC System
A malfunctioning HVAC system could allow carbon monoxide to build up in your home. Working carbon monoxide detectors are therefore an important element of your home’s safety plan. Every six months, test your detectors. Replace the batteries annually.
Replace Filters and Batteries
The filters in your HVAC unit are also necessary for safe and efficient operation. The MERV scale is used to classify filters by providing information about the particle sizes they can trap. The lowest rating a filter can receive on the MERV scale is one, and the highest is 16.
The MERV rating of the filter you choose must be compatible with your HVAC system. Consult your owner’s manual for specifications. In general, residential HVAC systems tend to be compatible with filters with a MERV rating between one and 12.
A dirty filter blocks the flow of air, forcing your system to work harder and recirculating dust throughout your home. Change the filters at least every 90 days or whenever you can no longer see the filter material through the dirt and debris. Change the filter more frequently if you have pets in your home or family members with allergies.
Inspect the Exterior Elements of Your HVAC System
HVAC maintenance should include the exterior parts of the unit, such as external vents, flues, and the AC component. Clear brush, leaves, and branches from the area surrounding the exterior unit. Trim bushes and landscaping as necessary. Visually inspect the air conditioning lines to identify any leaks.
