It’s best to leave HVAC repairs to the professionals. But it’s helpful to understand why HVAC systems fail — and how they get fixed. Technicians are trained to deal with many different problems, but the most HVAC repairs fall into a few categories.
Finding and Repairing Refrigerant Leaks
To operate effectively, heat pumps and air conditioning systems need to be charged with a precise amount of refrigerant. While this refrigerant level is designed to remain constant, leaks can develop over time. This is especially true of older units that haven’t received proper HVAC maintenance. Insufficient refrigerant charge can severely hamper performance. This can result in poor temperature control and high energy bills. Leaks occur most frequently in evaporator coils. However, other trouble spots include Schrader valves, capillary tubes, and flare fittings.
Fixing Faulty Electrical Components
Loose and damaged wires. Blown fuses. Faulty temperature and airflow sensors. Stuck relay switches. Bad start and run capacitors. These are just a few of the common electrical issues that experts contend with when completing HVAC repairs. Unfortunately, while some of these problems are obvious, others are trickier to identify. Typical warning signs include short cycling, tripping breakers, and burning odors. You may also hear persistent humming or notice the unit doesn’t start or stay running.
Replacing Worn-Out Mechanical Parts
All heating and cooling systems experience wear and tear during normal operation. This is why regular HVAC maintenance is so important. Without it, minor damage can accumulate and eventually cause major breakdowns. Belts, bearings, and blower motors are all common points of failure. But these can usually be repaired or replaced without much trouble. Other components, such as compressors and heat exchangers, might be a different story. These parts can sometimes be very costly, making it more economical to replace the entire unit.
