Heat pump repair for Austin's all-electric homes

Heat pumps are everywhere in Austin, from newer builds in Leander and Pflugerville to all-electric homes in Sun City. The same system cools your home all summer and heats it in winter, so it works almost year-round and wears harder than a furnace that only runs a few weeks a year.

Kassa Kool is engineer-owned. We measure refrigerant pressures, temperatures, defrost operation and electrical readings instead of guessing, then fix what's actually broken. We service central heat pumps, dual-fuel systems with a gas furnace backup, and ductless mini-splits.

Signs your heat pump needs repair

  • Cool air in heat mode, or warm air in cooling mode
  • The outdoor unit is covered in solid ice for hours
  • The system runs constantly but the house never reaches the set temperature
  • The thermostat shows “aux heat” or “emergency heat” most of the time
  • Loud grinding, buzzing or banging from the outdoor unit
  • The outdoor fan isn't spinning while the unit runs
  • Your electric bill jumped and nothing else changed

What's normal for a heat pump

In heat mode, air from the vents feels warm but not hot, cooler than a gas furnace. On cold mornings, the outdoor unit may frost over, then switch into defrost for a few minutes with a whoosh and some steam. Both are normal. Solid ice that doesn't clear, or air that feels cold, is not.

Common heat pump problems we fix

Defrost problems

A failed defrost control board, sensor or relay lets ice build up until the outdoor coil can't move heat. We test the defrost cycle and replace the part that's failing.

Reversing valve failures

The reversing valve switches the system between heating and cooling. When it sticks or its coil fails, the heat pump runs in only one mode or blows the wrong temperature air.

Refrigerant leaks

A heat pump doesn't use up refrigerant. If it's low, there's a leak, and a low charge hurts heating and cooling. We find and repair the leak instead of just topping it off.

Capacitor, contactor and fan motor failures

These parts take a beating from Texas heat and year-round use. A weak capacitor or worn contactor can keep the compressor or outdoor fan from starting.

Backup heat strip problems

Electric heat strips in the air handler help on the coldest days. Burned-out elements, failed sequencers or tripped limits leave you without backup heat when you need it most.

Thermostat and mini-split control issues

Heat pumps need a thermostat set up for heat pump operation. Wrong settings, a bad wire or a failed mini-split board can make a healthy system act broken.

Bogdan lives in my neighborhood so when I noticed that my AC wasn't cooling as well as it used to I gave him a call. He was able to come out and diagnose my issue as a leaking evaporator coil within a day and he recharged to keep it going. Also he followed up on my Trane warranty to get the coil replaced which was done the following week. The part was covered under warranty but I did have to cover the cost for the refrigerant and labor. Overall I'm happy with the service and I'll go with Kassa Kool again if I have any issues in the future !

Had a noise issue with my newly installed AC (by a different company) which they were not able to fix or even to diagnose and insisted that’s how it’s supposed to sound. There is no way I could live with that , so I reached out to Kassa Kool who was quick to respond and fix the problem. Owner is very knowledgeable and was able to address the problem on my Trane unit in the same visit. Reasonably priced, I will become their maintenance customer from now on.

Before you call: quick checks

  • Make sure the thermostat is set to the right mode, Heat or Cool, and not Emergency Heat
  • Replace a dirty air filter
  • Check the breakers for both the outdoor unit and the indoor air handler
  • Clear leaves, plants and debris at least two feet from the outdoor unit
  • Make sure the outdoor disconnect box near the unit is switched on

Never chip ice off the outdoor coil or pour hot water on it. That can damage the coil. If the ice doesn't clear on its own, turn the system off and call us.

How a heat pump repair visit works

  1. Call or book online. Tell us what the system is doing and which mode it's in.
  2. We diagnose. We test both heating and cooling modes, the defrost cycle, refrigerant pressures and electrical parts.
  3. You get a firm price. We explain what we found and what it costs before any work begins.
  4. We repair and test. We run the system in heating and cooling before we leave.

Should you repair or replace your heat pump?

Because a heat pump runs most of the year in Austin, an older one can reach the point where repairs stop making sense sooner than a furnace would. We'll give you a straight answer based on its age, condition and repair cost. If replacement is the better value, see heat pump and AC replacement and financing and rebates.

Keep your heat pump running year-round

A heat pump needs care in both seasons. Our maintenance plan covers a spring cooling tune-up and a fall heating tune-up for $16.67 a month, with priority scheduling and 10% off repairs. Mini-split plans are available too.

Heat pump repair FAQ

How much does heat pump repair cost in Austin?

It depends on what failed. Parts like a capacitor, contactor or defrost sensor are usually affordable, while a reversing valve or compressor costs more. We charge a trip and diagnostic fee, which can be waived for certain repairs, and you get a firm price before any work begins.

Why is my heat pump blowing cold air in heat mode?

Heat pump air always feels cooler than furnace air, but if it's truly cold, common causes are a stuck reversing valve, low refrigerant, a defrost problem or a thermostat setting. Check that the thermostat is set to Heat, then call us if it doesn't improve.

Is it normal for my heat pump to have ice on it?

Light frost on cold mornings is normal, and the unit should clear it with a short defrost cycle. A thick block of ice that stays for hours means the defrost system or airflow needs attention.

What is emergency heat, and should I use it?

Emergency heat runs only the backup electric heat strips and skips the outdoor unit. It's meant for when the heat pump itself has failed. It keeps you warm but costs much more to run, so call us to get the heat pump fixed.

Do you repair ductless mini-splits?

Yes. We repair ductless mini-splits from major brands, including Mitsubishi, and offer mini-split maintenance plans.
