A/C Repair  

If your air conditioner or heat pump is not cooling your home, we offer one of the best AC repair services around Sun City. You might notice the unit is not turning on at all, not cooling well, or maybe just part of the system works. When service is needed there are many variables like poor system design that can cause things to go wrong.  Smaller components like the run capacitors can cause the need for AC repair, but they shouldn’t as long as you have routine maintenance. Our technicians are prepared for any scenario that calls for AC repair service because they are experts in the industry.

Heat Repair

We offer our heat repair service for gas furnaces and heat pumps. While furnaces use gas combustion to heat homes, heat pumps work like an AC but they have a reversing valve that also allows them to heat with freon. Our technicians spend a lot of time staying up do to date on the latest HVAC equipment and what they can expect from older builds to offer the best repair service. Heat is mostly needed in the night and early mornings, that’s why we have technicians on call 24/7, so you don’t spend a night uncomfortable.

Causes Of Breakdowns

AC and Heat Pump Breakdowns

  • Freon Leak: Air conditioners use Freon to cool your home; unfortunately the system of coils that moves it can get a leak from vibrations and corrosion. If your system leaks out enough Freon it will not have the capability to adequately cool your home.
  • Thermostat and Electrical Connections: The thermostat is the brain of your air conditioner, it is very important that the connections between your units components and the thermostat is maintained. Your thermostat or electrical connections could be experiencing a connectivity issue that will prevent your system from working.
  • Capacitors: A lot of air conditioners use run capacitors and start capacitors for their motors. If the start capacitor has gone bad then your components won’t start and the run capacitor going out will prevent them from running after starting.
  • Lack of Maintenance: Not having annual checkups means you haven’t been taking care of your unit. There may have been problems that could have been prevented by having an annual maintenance visit because the technician could have told you what to do to prevent a breakdown. A lot of times, filters and coils get dirty and cause motors to fail because they have to work a lot harder to satisfy your systems thermostat.

Gas Furnace Breakdowns

  • Heat Exchanger: In the furnace the heat exchanger heats up the air passing through it that in turn heats up your home. If you have a dirty filter it will restrict airflow which will cause the heat exchanger to expand and crack. Also avoid closing vents as that also reduces airflow.
  • Electric Ignition or Pilot Light: Without these components your air conditioners furnace wont be able to start. Electric ignition is becoming standard you may not have a pilot light. These components go out every few years make sure you have maintenance to prevent a breakdown.
  • Combustion Chamber: This component is necessary for any combustion to occur and create heat. It does this by mixing fuels and transferring heat to the heat exchanger. Corrosion and lack of maintenance could have caused this component to fail.
  • Bad Capacitors: If a run or start capacitor has gone bad on a blower motor then it won’t work which will prevent any warm air from being distributed. Have an HVAC company out to fix this problem.

Your homes AC and heating system must have routine maintenance check ups every 6 months in order to maintain its efficiency and prevent breakdowns. When running an A/C and gas furnace combination well check each side once a year, cooling for summer and heating for winter. Heat pumps are checked twice a year since they can cool and heat. Prevent breakdowns by having us out routinely that way our expert technician can identify anything that is going to breakdown or cause one. We can also help improve the efficiency of the system, just let us know if your utility bills are high.

AC and Heat Pump Checklist

  • Check Thermostat Operation: Your thermostat is the brain of your air conditioning system and is checked to make sure your system is cycling on and off appropriately.
  • Clean or Replace Standard Filter (Customer Supplied): If you give us a filter to replace we will replace it for you because the filters are a very important part of the AC unit. They keep your units indoor coil clean which is a big part of the systems efficiency. Changing them will also help your unit have better airflow as long as they are clean.
  • Check Air Flow: After changing your filter as long as you have given us a new one, we will check your systems airflow and make sure there is good air distribution.
  • Check Your Air Conditioner’s Refrigerant Charge And Adjust As Needed: The freon your air conditioner uses is necessary to cool down your home and heat it up if using a heat pump. We will help you out with 1lb. if your unit is running low. (Refrigerant leak checks, repairs, and adding refrigerant beyond 1 lb*. will incur additional costs.)
  • Lubricate Motors (if applicable): Older air conditioners have bearings that are not sealed down to the bearings so if you have an older unit we will help it work more efficiently by lubricating it.
  • Inspect All Electrical Components, Fan Blades, And Coils: These components if they have any wear and/or damage will cause losses in the efficiency of your system. Fan blades may need to be replaced or coils may just need to be cleaned.
  • Tighten Loose Electrical Connections: Loose connections can cause your system to work improperly and in turn lose system efficiency. If the connections aren’t addressed they can get worse and cause a breakdown.
  • Check And Adjust Fan Speeds: The technician may find that your fans on the wrong speed which if he does and fixes, you will have better air distribution and that will save you money by satisfying the thermostat better.
  • Inspect Drain Line and Drain Pan: During monsoon season when there is a lot more water in the valley, your unit will need to drain. Our technician will let you know if your units ready to drain.
  • Digitally Record Air Temperature Differential Between The Supply And Return Air: The temperature differential will tell the technician if your system is cooling off the air enough. When cooling there needs to be about an 18-degree difference between what is going into the ductwork and what is coming out.

Gas Furnace Checklist

  • Check For Any Gas Leaks: Gas leaks if caught soon enough will prevent carbon monoxide poisoning, fires, or even explosions!
  • Check The Pilot Light: The pilot light gets the rest of your heating system started we need to make sure its going to operate properly for the winter.
  • Inspect The Main Burner: Your fuel for your system needs to be mixed and burned in order for heat to be transferred which is why we like to make sure that the main burner is going to operate properly.
  • Inspect The Main Gas Line: The main gas line delivers the gas to your furnace, its important that there are no leaks so that your system is efficiently burning all the fuel it receives.
  • Check The Main Shut Off Valve: We check the main shut off valve to make sure it works in case of an emergency, where your gas line needs to be shut off.
  • Carbon Monoxide Check: We will check if there is any carbon monoxide in the home from your furnace because it’s deadly. If you don’t have a carbon monoxide sensor in your home you should talk to your technician about getting one.
  • Check Limit Controls: The limit controls will control when your fan turns on and off. We check them to make sure your fan is operating efficiently and not wasting money.
  • Inspect The Thermocouple: We check the thermocouple for proper placement and signs of deterioration; it’s important because it measures how much heat is being generated.
