Simple Tricks from Our Cooling Experts to Try Before You Call:

It is a common thought to pick up the phone and call for service when central air conditioning systems are not working right. However, you may find that the problem is something you can easily fix yourself if you follow our guide below. If you are uncomfortable with checking any of these things, just call for service and let one of our cooling technicians inspect the air conditioning unit for you.

Make sure there is power to the A/C unit

  • Try turning the fan to “ON” on the thermostat to test for power to A/C.
  • If nothing happens, reset the breakers at the electrical panel, especially if the thermostat is showing a blank reading.

Make sure your vents are open

  • Check all return air grilles and registers. Make sure they are not blocked by furniture and are open and blowing air.

Check the batteries in your thermostat

  • Some thermostats still operate on batteries, even if they are also wired to the home. If the rest of your house has power, but the display on your thermostat is out, change the batteries to see if that fixes the problem.

Check the air filter

  • If it’s been more than a couple of months since you changed your air filter, you should check to see if it requires replacement. Your central air conditioning system may suffer irregular performance due to clogged filters. Try replacing the filter and see if that solves your problem.

Check that your power is on

  • There could be power outages in your area.
  • Check the breakers that power your air conditioning equipment and reset them if they are tripped.
  • Make sure the ON/OFF switches on indoor and outdoor cooling equipment are set in the ON position.

Clear away obstructions from the outside unit

  • Leaves, grass, and debris block the unit from receiving enough air flow. Leave a two-foot radius around the unit to give it enough room to receive adequate air flow for proper performance.

Check the temperature setting on your thermostat

  • Make sure the thermostat temperature is set lower than the current indoor temperature.
  • Make sure the thermostat is set to the cool position.

Check your condensation drain lines

  • These lines can become obstructed for various reasons. Try blowing compressed air into the line to dislodge any obstructions, then pour a solution of half-bleach and half-water through the line to get rid of any mold.

If you have an air handler, check the following:

  • Make sure the access panels have not come loose. Some units have safety switches that cut power to the air handler if the panel is loose or removed.
  • Check the drip pan to see if it’s flooded with water. If so, you have a clogged condensation line and it needs unclogged before the system operates normally again.

Is your air conditioner freezing up?

  • Dirty air filters can cause your system to freeze up because they impede the airflow. Check your filter to see if it needs replaced.
  • Other causes could be dirty coils, a broken air handler fan, obstructed vents, or a low refrigerant charge.

Is your A/C unit cycling on and off?

  • Make sure an air register isn’t blowing directly on your thermostat.
  • Change your air filter and change it if it is dirty.
  • If these solutions don’t solve the problem, your unit may be wrongly sized – in this case you’ll need to consult with an expert.

Common Cooling and A/C Terminology

There are many words and acronyms used in the HVAC industry that experts use throughout their conversations. It’s easier to make an informed decision when you know the common terms.

Air Handler

A device used to regulate and circulate air as part of an HVAC system. It’s usually a large metal box containing a blower and heating or cooling elements.

Air Flow

The volume of air moving through a blower or duct.


The sheet metal transition piece that connects to the duct on one side and has a grille or register on the other.

Checking the Charge

When your AC technician puts gauges on the system, he or she is measuring the pressure of the refrigerant to see that the system has the proper amount, or if a leak has allowed refrigerant volume to drop.


The part of the A/C unit that transfers heat carried by the refrigerant.


The part of your air conditioner that is responsible for most of the noise. It sits in the outside part of your A/C unit and raises the pressure and temperature of the refrigerant.

Cooling Process

Air conditioning systems cool homes by extracting excess heat, rather than creating cooling. The air conditioning system’s evaporator coil absorbs heat from the home, and the refrigerant within carries heat to the outdoor condenser unit, where it is released into the environment.

Fan Coil Unit

A device that uses a coil and a fan to heat or cool a room without connecting to ductwork.

Geothermal Heat Pump

Sometimes it’s referred to as a ground source heat pump (GSHP). A geothermal heat pump dumps or pulls heat to or from the ground or a body of water.


The cover of your return air vents.

Heat Pump

Part of the HVAC system that can be used to either heat or cool your home. A compressor circulates refrigerant that pumps and dumps heat as it travels between the indoor and outdoor units.


The working fluid that carries the heat. Most current air conditioners use either R-22, which began its phase-out in 2010, or R-410A. Before the Montreal Protocol to protect the ozone layer, most AC refrigerants were CFCs. R-22 is an HCFC, and R-410a is a hydrofluorocarbon.

Split System

An air conditioner with the condensing unit outside and the air handler and evaporator coil inside the home, connected by the refrigerant lines.


This is a method of heating or cooling different areas (or rooms) within one house independently – usually by using separate controls, or by opening and closing dampers within ducts in each zone.

Frequently Asked Questions

The most common problems an air conditioner will experience: A/C doesn’t turn on, not blowing cold air, A/C leak, making loud noises, and your A/C freezing up outside the unit.

There are many issues that could prevent your air conditioner from working correctly. One issue could be that you have a blocked or clogged condenser coil.

Most air conditioning units will last 12-20 years, depending on the type of system and how well kept the system is.

It would be recommended to increase the set point of your thermostat when you are away. We do not recommend turning off the unit entirely as it will take a significant amount of energy to bring the home back down to temperature and can introduce problems for appliances and furniture if the temperature and humidity get too high.

Dirty filters will cause poor cold air flow in your air conditioning system. This can cause more severe problems, such as your air conditioner freezing up and becoming inoperable.

Usually this happens because the compressor/outside unit has a problem, or your A/C is low on refrigerant.

Loud noises from your air conditioner can indicate that something is seriously wrong with your unit. The first thing you should do is turn off the system and call a professional to diagnose the problem.

Before resetting your air conditioner you should turn off your A/C at your thermostat. Once the unit is turned off, go to your circuit breaker box and reset the air conditioner from there. Wait 30 minutes, then turn the thermostat for your A/C back to the cool setting.

Signs that your A/C unit is broken include: uncomfortable temperatures inside your home, vents pumping warm air, and loud noises coming from your air conditioner.

For your air conditioning unit to run efficiently and effectively, regular maintenance is required. Preventative maintenance keeps your unit healthy and helps prevent larger issues from happening.

It’s recommended that you should clean your air conditioning coils at least once a year.

More advanced systems may run longer but at a lower energy level to increase the efficiency of the unit and comfort of the home.

SEER ratings measure the maximum energy efficiency over the range of expected seasonal temperatures. In general, good SEER values range from 14 to 16 for air conditioning units. These are most common. There are more efficient unit available to decrease the energy costs of your home.
