Staying on top of home maintenance ensures your equipment is ready to go when the seasons change. That’s why you should prepare your air conditioner for spring and summer before the warmer temperatures hit. Below are a few tips to consider, from cleanup to calling your HVAC contractor for service.

How to Prepare Your Air Conditioner for Spring & Summer

1. Change or Clean the Filter

Filters catch allergens and dirt to keep them from blowing into your living space. Changing or cleaning them helps maintain quality indoor air, and the task should be performed every couple of months. If you haven’t changed yours in a while, just before spring is ideal so that any dust accumulation from winter is purged.

2. Clean Vents & Registers

Vents and registers also accumulate dust and allergens. If you have a pet, their fur will most likely find its way into these areas, so vacuum each vent before turning on the system. Remove grates and wipe down each slat to remove dust stuck in crevices.

3. Check the Thermostat

Test the device to ensure it turns on the AC and keeps your living space at the proper setting. For digital versions, ensure that it follows any preset schedules, and take note of any problematic cycling on and off. If you notice issues, you may need to recalibrate or update the thermostat.

4. Test the Unit

Once you have cleaned everything and tested the thermostat, take note of how your equipment runs. Listen for any odd sounds and ensure cool air comes out of the vents. If the air is warm or you hear or smell something out of the ordinary, set up an appointment with an HVAC contractor for air conditioning repair.

5. Call the Professionals

Even if your system is in top shape, annual maintenance keeps it running well for longer. HVAC contractors can service your system by cleaning and tightening components and inspecting for signs of early trouble. Staying ahead of maintenance is a preventative measure that will save time and money and ensure you’re not stuck without AC in the middle of summer.
