Common Issues We Repair

Many times, your HVAC system provides early warning signs that it is about to break down and needs repairs. Cold weather can cause problems for heat pumps. One common problem is ice on the outside unit. While some ice is okay, too much ice can cause issues.

A faulty reversing valve can also prevent the system from switching between heating and cooling. Low refrigerant levels can reduce performance, even if the system appears to work fine. Ductless mini-splits can develop issues such as leaks, clogs, or sensor problems. These issues can cause water damage, mold, or poor indoor air quality. Sometimes, the indoor and outdoor parts do not communicate well, leading to poor system performance or shutdowns.

Schedule HVAC service if you notice signs like:

  • AC not cooling or blowing warm air
  • Furnace short cycling or not heating
  • Unusual noises or foul smells
  • Thermostat malfunctions
  • Poor airflow or uneven temperatures

Humidifiers can clog with mineral buildup, especially in hard water areas, which can block parts and slow down their work. Water leaks may occur from broken water lines or worn parts. A faulty solenoid valve, which controls water, can also get stuck or stop working. Frost on a dehumidifier’s coils can prevent it from removing moisture.

Drain problems, like clogs or disconnections, can cause water overflow and damage. A faulty sensor can give incorrect humidity readings, disrupting the unit’s operation. Air purifiers work less effectively if the filters are dirty or blocked, even if air still flows. If the model uses UV light, the bulb can burn out and stop killing germs. A broken fan motor can also stop air from moving through the purifier.

Schedule HVAC repairs in San Antonio, TX if you notice:

  • High indoor humidity level
  • Loud banging or grinding noises
  • Constant on and off cycling
  • Water leaks
  • Ice buildup

Air conditioners can freeze up if the airflow is blocked or the refrigerant is low. Dirt on the outdoor coils worsens the system’s heat release. Faulty capacitors stop the compressor or fan from working properly. A dirty flame sensor prevents a gas furnace from igniting and causes it to shut down for safety.

Blocked vents or chimney problems also stop it from functioning and create safety dangers like carbon monoxide. If the ignitor breaks, the furnace can’t light even if other parts are okay. Knowing the signs of these problems and fixing them quickly is important.

Signs You Need HVAC Repair

These warning signs often indicate an underlying issue, such as a refrigerant leak or a low charge. They can also indicate that you need to clean off the outdoor unit, that the evaporator coils in your system have frozen, or that the condensate drain is clogged. Failing to address these signs jeopardizes your home’s indoor comfort and can shorten the lifespan of your heating and cooling system.
