Is Something Off With Your Heat Pump?

Let’s Fix It Before It Gets Worse.

Heat pumps rarely fail without warning. If yours is acting weird, here’s what our heat pump repair contractor in San Antonio, TX sees and solves, most often:

Wrong Air Temperature

Heat pump blowing cold air in winter or warm air in summer? You’re probably low on refrigerant or dealing with a reversing valve failure. We’ll track down the issue and restore proper heating or cooling.

Won't Stop Turning On and Off

Short cycling wastes energy and damages components. Bad capacitors, clogged filters, or thermostat malfunctions are often responsible. We’ll diagnose and repair it quickly.

Uneven Heating or Cooling

If one room is perfect and another’s unbearable, you’ve got airflow problems, clogged filters, blocked ducts, or a struggling blower. We’ll balance your system room by room.

Unsettling Sounds

Hissing, grinding, buzzing, or banging aren’t normal. They usually mean refrigerant leaks, failing motors, or electrical problems. We investigate every noise source and fix it.

Ice Buildup You Can See

Frost on the outdoor unit or ice on indoor coils signals airflow issues or refrigerant loss. Both lead to compressor failure if left alone. We catch it early.

Quick Answers to Common Questions

What Causes Uneven Heating or Cooling in Different Rooms?

Uneven temperatures usually come from airflow problems, clogged filters, blocked vents, leaking ductwork, or a struggling blower motor. It is sometimes due to the wrong placement of a thermostat or the incorrect sizing of the system. Our technicians verify all your equipment, identify airflow limitations, and restore comfort balance throughout your house to make all rooms feel homely.

What If You Can’t Fix My Heat Pump the Same Day?

If we need to order a specialized part, we’ll explain the timeline and do everything possible to keep you comfortable in the meantime. In winter, we offer temporary heat solutions for your heating problems. During cooling problems in summer, we prioritize getting the part rushed and installed as soon as it arrives. We stay in communication every step of the way.

What’s the Difference Between a Heat Pump Repair and Regular Maintenance?

Preventive maintenance involves cleaning coils, inspecting refrigerant, performing electrical connection tests, and replacing filters before any trouble arises. Repairs address existing failures, such as refrigerant leaks, broken capacitors, or failed reversing valves. Routine maintenance, in fact, reduces repair requirements by identifying wear at an early stage. Sigma Air Heating & Cooling provides both services to ensure your system runs well year-round.

Why Is My Heat Pump Blowing Cold Air When It Should Be Heating?

This issue usually indicates that your system is low on refrigerant or that the reversing valve is stuck. A low refrigerant charge prevents the system from properly absorbing heat, while a faulty reversing valve can stop the unit from switching between heating and cooling modes correctly. Both problems require professional diagnosis and repair. Our heat pump repair service in San Antonio, TX, can identify the issue and restore your heat pump to proper heating performance.
