Air Conditioning Maintenance

Maintenance Service for Your Air Conditioning System by Houston’s Best and Most Recognized HVAC Service Providers Since 1994

Quality Guarantee

There are some AC maintenance procedures we always recommend the homeowner do if they are able. The most important is to replace your air filter at least every other month.

Old air filters strain your system and are often what causes other malfunctions. You can add at least 5 years to your system’s life by replacing your air filter when it needs to be replaced.

John Moore also sells Plumbers’ Formula 6, a drain cleaning fluid that should be used every 4 to 6 months to clean your condensate drain and prevent algae from growing inside.

Air Conditioning Repair

Have you noticed that the air in your home isn’t reaching the desired temperature or comfort level? Have you seen a spike in your energy bills?

Are there watermarks on your ceiling? Visible leaks around your outdoor unit? Has your AC system completely stopped working? If you notice any of these signs, it’s in your best interest to call an AC technician to fix the issue before it causes more problems for you, your AC system, and your home. To learn more about potential AC malfunctions and how we fix AC issues, visit our AC Repair page.

HVAC Replace

Air Conditioning Replacement

Is your AC system more than 10 years old? Are you constantly calling for repairs? Does your condenser still use R-22 refrigerant?

If so, you may want to consider replacing your entire AC system. After your AC system reaches a certain age, it makes more sense to invest in a new AC system altogether rather than repairing it one piece at a time. To learn more about John Moore’s AC replacement program, our warranty, and the cost-advantages of replacing your AC system, visit our AC Replacement page.
