Quality Guarantee

Ahh, yes. Where would we be without the refreshing comfort of AC in our homes? It’s easy to take AC for granted. After all, most of the people who read this page have probably enjoyed the comforts of AC in their home for their entire lives. But like a reliable friend, everyone misses their home’s AC when it’s gone, especially in Texas.

There is a lot that can go wrong with your home’s AC system over its lifetime: the condensate drain line can sweat and overflow; refrigerant can start leaking; air ducts can be crushed, contaminated, or built too small to begin with; and your compressor can fail.

Instead of waiting until your AC system stops working, it’s always good to be aware of how well your system is functioning. Regular maintenance can prevent a lot of these problems from getting out of hand, or even happening in the first place.

Signs that Your Air Conditioning System Needs Service

Is cold air not blowing out of your air registers even though you set your thermostat to cool? Do you notice that some rooms in your home heat or cool slower than other rooms?

Do some rooms not cool at all? Have you noticed a spike in your energy bill? Water marks on your ceiling? Or maybe that your AC system has totally stopped running.

If you notice any of these signs, you should call an AC professional as soon as possible. Every component of your AC system is connected, so one malfunctioning part could lead to further damage if it’s not addressed in time.

Basic Operation of an Air Conditioning System

Before we get into the different AC repairs and replacements that John Moore offers, it’s important to understand the basic operating principles of your AC system. There are two types of systems: electric and natural gas. Electric AC systems use an air handler to blow air through your home while natural gas systems use a furnace. Both furnaces and air handlers are typically located in the attic.

Cooling Cycle

Outside of your home is an outdoor unit, which is called a condenser. Inside the condenser is a compressor, a condenser coil, and a large fan. The compressor pumps cool refrigerant to an evaporator coil located either in the air handler or just outside the furnace. The evaporator coil gets really cold so that when the blower or furnace pushes warm air past it, the air is cooled. This cool air is then distributed throughout your home through a series of air ducts. Heat is absorbed by the evaporator coil, which warms the refrigerant moving through the coils. This warm refrigerant is then pumped back outside to the condenser coil, where a giant fan cools it off allowing the warm air to escape. This cycle is repeated until your thermostat detects that your home has reached the temperature you set it to.

Cooling Cycle

Heating Cycle

In electric systems, the air handler contains an electric heater that- like the name suggests- uses electricity to produce heat. A blower inside of the air handler then blows air past the heater to distribute warm air through air ducts and into your home.

In natural gas systems, a furnace takes the place of an electric heater. The furnace’s pilot light or electronic ignition lights the burner inside of a combustion chamber, creating heat in the furnace’s heat exchanger. The heat exchanger is a metal chamber that gets warm and heats up air as the air blows past it and into your home’s duct work.

HVAC Repair

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.

  • During August and September, I used John Moore for a new AC system with ductwork and insulation and a new attic ladder, new breaker unit, new wiring, and a new toilet. The Moore people were very nice and professional. JM may not be the cheapest around but they are the best and since my home is over 30 years, I needed to have it all done and done correctly.
