How Often Should an A/C System Be Serviced?

Posted: April 21, 2025

Annual Maintenance Is Vital

The last thing you want is for your cooling system to shut down on a hot, steamy day this summer. If you haven’t arranged your annual cooling tune-up yet, please reach out to us as soon as possible. We can find and correct any issues and restore your cooling system to peak efficiency.

We may also be able to do your heating tune-up on the same day, so your furnace or boiler will be in top condition to keep your home warm when the cold weather returns.

Benefits of Annual A/C Maintenance

After a long hibernation over the fall and winter, your cooling system needs attention so it can keep you cool all summer long without problems. That’s just one reason why maintenance is important. Manufacturers require annual maintenance to keep your warranty valid. It’s that crucial!

A central air conditioning system that has been properly maintained will have fewer breakdowns than one that has been neglected. Annual maintenance also keeps your equipment running at peak efficiency, which means your home stays nice and cool while using less energy.

Regular maintenance can address your air conditioner’s minor aches and pains before they become full-blown emergencies – which usually happen during peak summer months, when you need your A/C the most (and when service delays are more likely).

Other Ways to Get Your A/C System Ready

Although a comprehensive central air conditioning tune-up is not a do-it-yourself project, there are tasks you can do while waiting for your tune-up service:

• Remove sticks, leaves, and other debris from around your outdoor unit.
• Schedule a FREE duct leakage inspection with us. If we find problems, we’ll recommend our duct-sealing service. This will improve your indoor air quality and lower your home energy bills.
• Briefly run your cooling system to check for problems. That way, you can give us an early alert about what to look for when we do our maintenance service. Make sure the outdoor temperature is in the 60°F range before you do this, as the system is not designed to run below certain temperatures.

If you switch on your cooling system and it does not run, try the following:

• Check your thermostat: Make sure it is on the “cool” or “auto” setting and set about 5 degrees below room temperature. If the screen is blank, you may need new batteries or the power supply has been interrupted.
• Check all power switches/sources: A circuit may have tripped. Also, check the disconnect switch in the box next to the outdoor condenser.

If the system runs but there’s no cool air, try this:

• Shut off all power switches and check the condition of the air filter in your air handler. Replace or clean it if it’s dirty.
• Make sure your supply and return air grilles are open and unobstructed.

If you can’t find what’s wrong after taking these steps, call us so we can come out and diagnose the problem.
