Most Common HVAC Repairs and Cost in Raleigh

RankDescriptionAvg Cost
1Clear Clogged Drain LineA clogged drain line is the most common cause of water leaking from your AC into your home. If the drain line gets clogged with dust, dirt, sludge or mold, that water backs up into your home.$50-$175
2Replace CapacitorThis can be caused due to heating in operation. Heating can be caused by either wrong connection or the use of under-rated capacitors. In electrolytic capacitors heating can cause the formation of gas inside which can explode through the vent provided. Voltage surges can also cause capacitor failure.$120-$500
3Trace Leak/ Low RefrigerantThis corrosion will advance at quicker stages when there is more moisture present on the evaporator coils. Moisture develops from the air traveling across the coil and being condensed-just like rain clouds in the atmosphere. Undersized ductwork or dirt filters can cause a freon leak to develop at quicker rates.$150-$1800
4Replace ContactorA contactor is an electrical relay that controls the flow of electricity to components in the AC unit. The contactor sends voltage to the condenser and outdoor fan motor. Voltage from the thermostat is sent to the contactor and is registered by the contractor’s side terminals$130-$500
5Troubleshoot Thermostat1. The Heater or Air Conditioner Refuses to Start

2. Air Conditioner Runs Constantly and Won’t Turn Off

Heating and Cooling Statistics for Raleigh, NC

Heating and cooling degree days are a tool used to normalize energy use across different areas. Degree days are based on the assumption that at 65 degrees Fahrenheit no heating or cooling is necessary inside your home to feel comfortable. 

The following example calculations were provided by the National Weather Service, weather.gov.

Cooling Example:
The high temperature for a particular day was 90°F and the low temperature was 66°F. The temperature mean for that day was: 78°F
78°F – 65°F = 13 Cooling Degree Days
Heating Example:
The high temperature for a particular day was 33°F and the low temperature was 25°F. The temperature mean for that day was: 29°F
65°F – 29°F = 36 Heating Degree Days.
