    Our experience with Freon HVAC has been exceptional for a full panel upgrade to 200 amps and installation of a new Mitsubishi mini-split system in an old house. We took quotes from 4 different top rated hvac providers in the San Jose area, before deciding to go with Freon. I appreciated the honesty and detailed analysis of our needs by Slava when he first showed up to do an estimate. He asked a ton of questions, checked the house for existing setup, wiring, possibilities, and discussed multiple possibilities including ducted, gas, hybrid, and heat pump only. Once we decided to go with a specific type of configuration, he gave us multiple options. Their pricing was competitive and while it took forever for PGE to get to the wiring/transformer upgrade, Freon's team worked with them patiently to meet our needs. Special thanks to Jessica for regular follow ups with PGE and us. Once PGE scheduled the wiring upgrade (after 3 months), Freon's team was prompt and did a very clean install including all internal wiring and drainage work. They ensured city inspection was scheduled promptly and addressed all city concerns for a quick approval. I have not dealt with a more professional and competent crew in this area in a very long time. Would love to do business with them again.

    ​I usually doubt perfect 5-star ratings, but Freon completely earned theirs. My AC/heater combo unit broke, and every other company told me I needed a total replacement, quoting me between $9k and $12k. ​Freon came out to inspect it, and later that day, they gave me a quote for just $3,000 to repair it. I signed the contract that night, and they were back to do the work just 5 days later on June 19th. ​The tech replaced the compressor to get it running, but didn't stop there. He thoroughly tested the system, caught a power issue, and replaced the compressor relay and expansion valve to ensure the unit wouldn't break down again. Outstanding service. I'm finally set for the summer and winter. They deserve every single star!

    Repair or Replace Your Heat Pump?

    The $5,000 rule is a common budgeting guide: multiply the quoted cost by the system’s age in years. If the result exceeds $5,000, consider replacement alongside repair. This is a general guideline, not a technical standard. 

    ENERGY STAR recommends considering replacement when a heat pump is more than 10 years old. Age alone isn’t enough to make the call. Frequent breakdowns, declining performance, and costly repairs also matter.

    When replacement makes sense to consider, we quote both options so you can compare costs and decide what works for you.

    Answers to Your Recovery Questions

    Frequently Asked Questions

    A diagnostic visit with NEON costs $59, which goes toward the repair if you approve the work. The final price depends on the failed part, refrigerant requirements, and how easy the equipment is to access. 

    Heat pump lifespan depends on installation quality, usage, maintenance, and climate exposure. DOE uses about 15 years as an average lifespan in its cost calculations, but age alone does not determine when replacement is needed.

    Coastal homes may see more corrosion from salt air. Contact NEON for heat pump repair in San Francisco to help assess whether repair or replacement makes sense.

    Yes. We repair single-zone and multi-zone ductless mini-splits in San Francisco, including systems with airflow, electrical, control, and refrigerant problems.

    We repair Mitsubishi Electric, Daikin, Carrier, Bosch, Trane, Rheem, Lennox, Goodman, York, and American Standard systems. Parts availability varies by brand, model, and age. If a part is no longer available, we’ll check the alternatives and explain your options. 

    Same-day service may be available, depending on our schedule, the problem, and the parts needed. Refrigerant work or hard-to-find parts can take longer. We’ll explain the timeline after checking your system. 

    If your system isn't heating your home properly, start with a few basic checks. Make sure the thermostat is set to Heat and the temperature is set higher than the current room temperature. A clogged air filter or tripped circuit breaker could also be the cause. Keep in mind that a heat pump may briefly blow cool air during a defrost cycle. That's normal. But if the heating problem persists or the breaker keeps tripping, schedule a diagnostic visit.

    If your heat pump isn't cooling properly, start by checking the thermostat and air filter. Set the thermostat to Cool and make sure the temperature is below the current room temperature. A dirty filter or restricted airflow may be causing the issue. Other possible causes include refrigerant leaks, electrical problems, or faulty fans and compressors. Still getting warm air? If the problem continues or your system keeps shutting off, contact NEON for heat pump service in San Francisco.
