When It’s Time For AC Repair

When you can handle minor repairs yourself – such as clearing out a sink, changing an air filter, fixing window latches or fixing leaky pipes – with confidence, you may feel proud. But when the task becomes too challenging or intricate for you to handle it yourself, it’s time to call in experts for assistance.

Air conditioning repair is no different. Regular AC maintenance is essential to keep your system running optimally and reducing the chance of breakdowns.

Thermostat for AC Unit

The thermostat is an essential component of your air conditioner system, despite its small size. It plays a significant role in maintaining the efficiency of your system’s operations.

Normally, your thermostat controls when your AC turns on and off; this ensures that it performs its cooling or heating functions appropriately. Unfortunately, issues with the thermostat may lead to various complications for your HVAC system.

A malfunctioning thermostat can lead to a variety of issues, from inconsistent temperatures to broken connections that cause your AC unit to short-cycle. Not only does this reduce its lifespan but it may also significantly raise your electricity bills.

Evaporator Coil of AC Unit

The evaporator coil is an integral component of your air conditioning system, working in concert with the condenser coil to absorb heat from indoor air.

This coil is typically attached to your furnace or situated inside your air handler and plays an essential role in improving your home’s energy efficiency.

Maintaining an evaporator coil’s cleanliness is essential for its efficiency. A thick layer of dust can restrict its capacity to absorb heat and cool air, costing you money on your energy bill.

An evaporator coil is typically constructed with an A-shaped surface and coiled tubes that loop back and forth. It’s a universal part that can be utilized by most brands and HVAC systems.

Compressor for Air Conditioning Unit

The compressor is the foundation of any effective air conditioning system. It converts low-pressure refrigerant into a high-pressure gas, then reverses it back into cool liquid for injection into evaporator coils in your home’s ductwork.

Compressors come in two types, reciprocating and rotary vane. Reciprocating compressors use pistons driven by a crankshaft to compress gases (arrows in photo).

Many air compressors are powered by either electric motor or internal combustion engine, though electric-run compressors tend to have lower noise levels than their gasoline-fueled counterparts. Alternative fuel options may also exist such as hydraulically powered compressors that don’t produce exhaust fumes.

Fan Motor for AC

The fan motor is an essential component in your air conditioning system, often referred to as its “heart.” Unfortunately, if not taken care of properly, this component may fail prematurely.

Your fan motor keeps your compressor from overheating by cooling the superheated refrigerant that passes through AC’s condenser coils. Without it, your system will struggle to cool your home effectively and may require costly repairs in the future.

If your fan motor is not working, try restarting it with a screwdriver or stick. If that doesn’t work, chances are you need to replace the capacitor in your device.


Ductwork is essential to heating, ventilation and air conditioning (HVAC) systems in order to distribute conditioned air throughout a home. Without properly designed ductwork, airflow in your house could become unbalanced and the system less efficient.

It is essential to have a professional inspect your ductwork for leaks and contamination, such as dust, germs, mold or other allergens that could negatively impact indoor air quality. If left undetected, these issues could cause health issues and even result in higher energy bills.

Leaks in ductwork can be quickly and easily fixed with a handheld tape measure and metallic foil tape specifically designed for this purpose. Doing so will improve your system’s efficiency and lower utility bills.
