Is Preventative AC Maintenance Necessary?

Before we can answer this question, how would you answer the following: “Is an oil change necessary for your car? Do you really need to replace the ink in your printer? Does your dog really need that rabies booster shot?” The short answer to all of these questions is an emphatic “Yes!” Find out in our tips what steps you can take for preventative AC maintenance here.

DeHart has spent the last century improving the homes of Oklahomans. We have seen first hand how regularly scheduled maintenance for your air conditioner can keep your home cool during the hot Duncan and Chickasha summers, save you money on cooling costs, increase indoor air quality (IAQ) and even extend the life expectancy of your air conditioner. Here’s how.


First and foremost, regular AC maintenance will catch a small issue before it turns into a big problem. Our AC maintenance includes lubricating any moving parts to prevent additional wear and tear, as well as inspecting all other parts for signs of failure. When this is done regularly, you can rest easy knowing your AC is operating at peak efficiency and that your risk of a sweaty AC breakdown in the middle of the hot summer is minimized to nearly zero. When you compare the cost of an emergency repair to the cost of maintenance, it’s a no brainer.

Our Dehart AC technicians will tell you the most beneficial course of action when it comes to your air conditioner, from basic repairs to full AC replacement. Your home comfort and lasting energy savings are our only goal!


After any deteriorated parts have been replaced, and all moving parts have been lubricated and optimized, DeHart’s AC maintenance technicians will also replace your air filters to ensure that your air conditioner is running as efficiently as possible. A dirty air filter will force your air conditioner to work harder to pull in the air it needs, therefore costing you more each month on your cooling costs and causing an increase in wear and tear. Plus, a dirty air filter will lose its ability to keep your breathing air clean and healthy! Replacing your air filter regularly is essential maintaining healthy IAQ and the overall health of your home.


The key to properly maintaining your air conditioner is to schedule professional maintenance before you are at risk for an unexpected breakdown. It is difficult to tell if your air conditioner is struggling to keep up with your cooling needs — there is no check engine light like in your car, and there are no “low ink” warnings like with your printer. But there are a few things you can look out for:

  • Higher than expected cooling bills
  • Loud clanking or banging noises
  • Low air flow coming from your vents
  • An increase in allergy-like symptoms in your home

Don’t fall into the trap of waiting for an air conditioning emergency before you schedule your AC maintenance. Take the proactive approach with professional AC repair and maintenance from DeHart, and set your home up for a cool, energy efficient summer here in Chickasha and Duncan!
