6 Common Repairs Made to HVAC Systems in Canyon Lake, TX

Modern HVAC systems don’t break down very often, but when they do, they tend to fail in predictable ways. For Canyon Lake, TX, homeowners, understanding the most common heating and cooling repairs and recognizing their warning signs can be extremely valuable.

Airflow and Blower Motor Issues

If your HVAC system can’t efficiently distribute air, it can’t properly heat and cool your home. This forces it to work harder and run longer, putting great stress on your equipment. The good news is that airflow issues are usually easy to detect.

The most obvious sign, of course, is simply less air blowing from some or all your vents. Other potential indicators include rising energy consumption and hot or cold spots around your home. Poor airflow is often caused by dirty filters and AC coils, but a failing blower motor is another likely culprit.

Faulty Thermostat Controls

Thermostats may seem simple, but they employ some sophisticated technology to keep you comfortable. Sensors continually monitor the conditions in your home, sending signals to your HVAC system whenever it gets too warm or cool.

When these sensors malfunction, they can sometimes generate inaccurate readings, causing your system to start or stop at inappropriate times. This can create uncomfortable temperature fluctuations and leave your home hotter or colder than your chosen setpoint. A problem like this can typically be solved by having your thermostat recalibrated, though some hardware failures may require replacement.

Improper Refrigerant Charges

To effectively absorb, transport, and release heat energy, air conditioners and heat pumps require a specific amount of refrigerant. In a normal system, this value — referred to as the refrigerant charge — shouldn’t change much with time.

If the refrigerant charge is too low, your system may run for long periods of time without providing much comfort. You may also notice bubbling or hissing sounds, higher energy bills, and ice buildup on the evaporator coils. These are clear indications of a refrigerant leak, which needs to be identified and repaired before your system can be recharged.

Electrical System Malfunctions

From heat pumps to gas-fired furnaces, electrical components help to power and control all types of HVAC systems. These components can eventually wear out, corrode, and even fail completely without proper maintenance. Electrical issues are often intermittent, making them difficult to track down and identify.

Your HVAC system may randomly shut down, cycle too frequently or refuse to start at all. In some cases, electrical problems may also cause your circuit breaker to trip. This isn’t necessarily concerning if it happens once, but multiple tripped breakers demand urgent attention.

Furnace Ignition Problems

While older furnaces used a pilot light to spark combustion, most modern furnaces utilize a component known as a hot surface ignitor. These electronic ignition systems are safer and more efficient, but they can still occasionally malfunction.

Since this is potentially dangerous, furnaces have built-in safety features to trigger an automatic shutdown in response to any ignition failure. Consequently, a faulty ignition will usually cause your furnace to rapidly cycle on and off or fail to start altogether.

Bad Compressor or Condenser Fan Motor

The compressor and condenser fan motor are the primary components you’ll find inside your AC or heat pump’s outdoor unit. Although they perform different functions, they produce many of the same symptoms when they aren’t working correctly.

The most common signs include excessive vibration, banging or rattling noises, a lack of cold air, and hot, burning odors. A failing compressor may also cause tripped circuits or leave small pools of moisture around your outdoor HVAC unit. These components can be costly to repair or replace, so quickly acting is critical.

If you’ve noticed your HVAC system doing something out of the ordinary, don’t wait for the problem to get worse. Call Climate Control Heating & Air for timely, high-quality heating and cooling repairs backed by a 100% satisfaction guarantee.
