You can help prevent emergency service calls and avoid excessive repair cost by taking certain precautions and ensuring your HVAC equipment is operating according to manufacturers recommendations.
DIY Preventative Maintenance Tips
You should also hire a professional HVAC technician to inspect your heating system in the fall and your cooling system in the spring. An HVAC service professional can tune up your air conditioning system before you begin using it in the summer.
- If power was disconnected to your central air conditioning system during the winter, wait 24-hours after turning power back on to the system to run it. This gives the compressor time to warm up and function properly.
Keep the thermostat constant.
Replace air handler filters on a regular basis, and don't block vents or ducts inside the house to assure air flow in the home.
- Open air vents on the second floor at about 75 percent, and ensure other vents are equal and not closed. This helps the temperatures on the second floor remain even.
- Install an attic fan, or ensure your attic fan is functioning properly, to help ventilate hot air out of the attic.
- Keep leaves, weeds, grass trimmings, foliage and other dirt and debris away from the outdoor heat exchange unit, and clean the a/c coils according to the manufacturers' instructions. This includes shrubs and bushes around the unit.
