Spring has sprung, and that means summer is right around the corner, so it’s time to make sure your air conditioner is ready for action. For many people, this isn’t a DIY job.

Call the experts at Sears Home Services, and a technician will come out to do a full inspection and make sure all systems are good to go. That way, your air conditioner will be ready to keep you cool this summer. Regular HVAC maintenance can help your air conditioner run more efficiently and prevent costly repairs down the road.

Lennie Arroyo, district manager for Sears HVAC service, gives the inside scoop on the inspection process that Sears experts will perform.

Sears Spring HVAC Preventive Maintenance Check, Step by Step

1. Check the thermostat

The first step is to check the thermostat inside your house to make sure it’s still properly attached and is working properly.

2. Check the airflow around the air conditioner unit

Next, the technician will head to the outside unit. It’s important you have about 2 feet of space all the way around your air conditioner. That helps ensure there’s proper airflow around the coils so the unit can breathe.

3. Check the wiring

Your technician will cut the power to the AC. With that safely off, it’s time to open up the panel and check the wires to make sure they’re connected properly and not burned.

4. Inspect the contactor and capacitor

Your technician will also inspect the contactor as well as the capacitor and make sure it’s not swollen.

5. Measure the refrigeration pressures

Next, the tech will put gauges on your unit to check the refrigeration pressures. Are they set per the manufacturer’s design? If they’re too high or too low, service might be needed.

6. Check the compressor and fan

The compressor is the heart of the unit. Your technician will make sure it and the fan aren’t running too hard, which can cause the air conditioner to overheat.

7. Inspect the motor

Does it need to be lubricated? If so, the experts at Sears do so as part of the check.

8. Examine the air filter

Your tech will make sure the filter is clean and not restricted.

9. Clean the unit

The last thing your technician will do is carefully clean your air conditioning unit to help it run properly.
