John Moore: Trusted By Katy Residents for All HVAC Needs

If your AC is more than 10 years old and giving you trouble, you may want to consider installing a new air conditioning system. There are a lot of parts to your home’s A/C, and they all affect one another: the outdoor condenser unit houses your A/C’s refrigerant and condenser coil, which pushes cold refrigerant to the evaporator coil located in your furnace or air mover. A blower fan blows warm air that cools once it passes the evaporator coil and flows into your home’s air ducts. The refrigerant, which has now absorbed some heat, gets pumped back outside where it cools once again. On top of that, your home’s HVAC system has two condensate drain lines, one that drains condensation from the evaporator coil to a main drain line, and a secondary emergency condensate drain line that carries water to a spigot located under your roof’s soffit.

When your A/C reaches ten years of age, parts start to fail one at a time. Usually, the outdoor coil gets dirty, making it harder to cool and move refrigerant, leaving it vulnerable to cracks or leaks. This malfunction in refrigerant flow can freeze your indoor evaporator coil. On top of that, the insulation around your condensate drain line may start to deteriorate, leading to water damage in your ceiling. Furthermore, there are a plethora of mechanical and electrical parts that can malfunction within your A/C’s outdoor condenser.

Instead of paying to repair one part of your A/C at a time, it’s usually more cost-effective to put that money towards a new, more efficient A/C system. There are also a few rebates and tax-credits you can take advantage of when you upgrade!

Trouble Keeping Your Katy Home Cool? We Do Air Conditioning Replacement.

As we mentioned, you can run into many issues with components of your A/C system. But no matter what the problem is, John Moore’s certified HVAC technicians have a solution. Here are some signs to look for: water marks on your ceiling; rooms in your home that don’t reach the temperature set on your thermostat; loud noises coming from your outdoor condenser unit; and leaks or strange smells coming from your outdoor condenser.

If you want to keep your A/C system healthy and in full operating condition well past the 10 year mark, you should be maintaining it on a regular basis. Beyond replacing your home’s air filter every month, you should also be cleaning your coils and condensate drain line at least twice a year. John Moore’s $69 tune-up and inspection covers all the bases. We clean your air registers and coils, replace your air filters, clean out your drain line, and provide a full inspection of your A/C unit and catch any issues that could harm your A/C over time.

Notice something funny with you home’s air conditioning? Or just want to keep your system healthy? Contact John Moore!
