75 Degree AC delivers AC Heat Pump Repair for homeowners and light commercial properties with licensed, hands-on experience on both the heating and cooling sides of every system. Heat pump diagnostics are part of our daily workload, which means faults like reversing valve issues, defrost failures, and mode-switching problems are identified faster and repaired correctly the first time.
Heat pumps have to be checked in both heating and cooling mode because the system behaves differently in each one. Our contractors test defrost sequencing, reversing valve operation, and refrigerant movement across both modes so the actual fault is identified before any repair is recommended.
Every contractor on your central AC repair job is state-licensed and EPA-certified. We carry full liability insurance on every call. Your system is handled by someone who knows what they are doing.
You see the central air conditioner repair cost before a single tool comes out. No surprise charges, no add-ons after the fact. The number we give you is the number you pay.
We offer same-day central AC repair so your home is not stuck in the heat longer than it has to be. Call us in the morning and we work to get a contractor to your door that same day.
75 Degree AC has been repairing central AC systems in Houston for over 10 years. We are locally owned, not a franchise operation. We stand behind every repair we complete.
Call or book online. Let us know the symptoms: not heating, not cooling, ice on the unit, noise, or anything else you are seeing.
Our contractor tests the heat pump in both heating and cooling mode. Refrigerant pressures, reversing valve operation, defrost controls, and electrical components are all tested with meters.
Once the fault is isolated, we explain it in plain terms: what failed, why it happened, and what it takes to fix it. The flat-rate price lands before a single repair tool comes out.
Using manufacturer-grade parts matched to your brand and model, the contractor completes the repair on-site. Most heat pump jobs wrap up in a single visit without needing a second trip.
The system is tested in cooling mode and then switched to heating mode. Refrigerant pressures, airflow, and thermostat communication are all verified.
A heat pump does not generate heat by burning fuel. Instead, it moves heat from one place to another. In cooling mode, it works like a standard air conditioner, pulling heat out of your home and releasing it outside. In heating mode, it reverses the process, extracting heat energy from the outdoor air and moving it inside, even when temperatures are cool.
The reversing valve is the key component that makes this mode switch possible. Refrigerant flows through the system in opposite directions depending on whether the heat pump is heating or cooling. The compressor drives the refrigerant through the circuit, the indoor coil exchanges heat with the air inside your home, and the outdoor coil exchanges heat with the outside air.
75 Degree AC provides HVAC services across Houston TX, supporting residential and light commercial properties throughout the city. Our service coverage reflects how HVAC demand actually works in Houston, from central neighborhoods to outer city districts. Customers rely on us for consistent service standards, clear communication, and dependable system support city-wide.

Experience
AC Heat Pump Repair costs in Houston typically range from $150 to $700 for most common issues including refrigerant recharges, capacitor replacements, or reversing valve repairs. More involved repairs such as compressor replacement will run higher. We provide the exact repair price before any work begins.
A heat pump blowing cold air in heat mode is almost always caused by a stuck or failed reversing valve, low refrigerant, or a problem with the defrost cycle. In some cases, the system is stuck in cooling mode and cannot switch. A proper diagnostic tests each component before recommending any repair.
A heat pump running without cooling usually points to low refrigerant, a dirty evaporator coil, a stuck reversing valve, or a failed capacitor. The system needs a diagnostic that covers both modes because the fault may affect heating performance as well.
Most heat pumps last between 10 and 15 years with regular maintenance. The long cooling season and high humidity in this climate put extra wear on the system. Annual professional servicing and filter changes help heat pumps reach and exceed their expected lifespan.

DiazTrustindex verifies that the original source of the review is Google. Kenny Ho and his team were very communicative, professional, and helpful during the entire process. I had to replace an entire HVAC system and he recommended me the best unit efficiency and even worked with me to figure out different models to find the one that worked best for my situation, he even helped me make updates late at night the day before installation! The installation went very smoothly and him and his team got a removal cleaning, installing, configuring, and testing all from 9-5 same day! He even uses the best type of thermostats. At the end he walked me thru the final install and shared me the installation warranty for all parts. I will definitely work with him and recommend him as my go-to HVAC guy!Posted on Google Nicolas FablingTrustindex verifies that the original source of the review is Google.
