Heat Pump Services

Is your heat pump blowing cold air when it should be warm, cycling too often, or costing you more on your utility bill every month?

These are real signs that your system needs professional attention—heat pumps are complex, and problems usually get worse (and more expensive) if ignored. Plum HVAC handles these issues across Silicon Valley every day, and we’re ready to get your comfort back on track.

Heat Pump Installation & Replacement

When your heat pump can’t keep up, it’s usually more than just age—it’s a sign of deeper trouble or inefficiency that can’t be fixed with a band-aid.

Most homeowners first notice something’s off when the system struggles on hot or cold days, starts making grinding or buzzing noises, or just takes forever to reach the right temperature. If you’re hearing a loud compressor, smelling burnt electrical, or constantly resetting breakers, it’s time to stop pouring money into repairs and look at a replacement.

What we inspect before recommending replacement:

- Compressor operation and noise levels - Reversing valve function (for heating/cooling mode changeover) - Refrigerant pressure and possible leaks - Electrical connection integrity - Condition of evaporator and condenser coils

If we find repeated compressor lockouts, chronic refrigerant leaks, or a failed reversing valve, replacement is often the only move that makes sense. Unlike a quick Heat Pump Maintenance & Tune-Up, installation is all about sizing the right equipment, handling refrigerant lines safely, and ensuring your ductwork can actually deliver the air your new system puts out. We see a lot of homes where the last installer cut corners—undersized units, mismatched controls, or skipped permits—which leads to endless headaches later.

When a system is too far gone to repair economically, customers often pivot to Heat Pump Installation & Replacement instead of sinking more into temporary fixes. In many cases, pairing a new install with routine Heat Pump Inspection & Testing helps protect your investment and catch problems before they start.

Whether you’re upgrading from an older system or replacing a failed unit, our full-service Heat Pump Installation & Replacement coverage means you get the right equipment, installed right, every time.

Heat Pump Maintenance & Tune-Up

A healthy heat pump needs more than just a filter change—it needs regular, thorough attention to catch problems before they shut you down.

Skipping maintenance is the fastest way to end up with a frozen coil, a burnt-out fan motor, or a system that runs nonstop and never gets the house comfortable. If you notice reduced airflow, weird rattling or humming, or your system seems to run longer than it used to, it’s time for a tune-up.

What’s included in a real tune-up:

- Deep cleaning of indoor and outdoor coils - Checking refrigerant charge (and fixing leaks, not just topping off) - Inspecting and tightening electrical connections - Lubricating fan and motor bearings - Verifying thermostat calibration and system controls - Testing defrost cycle and backup heat operation

Most “quickie” tune-ups miss the real trouble: loose wiring that causes intermittent failures, dirty coils that kill efficiency, or stuck reversing valves that lock your system in one mode. We see plenty of systems that would’ve lasted years longer if someone had caught a $50 relay before it took out a $900 control board.

If a Heat Pump Inspection & Testing turns up issues, a proper Heat Pump Maintenance & Tune-Up can often prevent a small problem from turning into an emergency. And for homes with both heat pumps and traditional AC, it pays to sync your Air Conditioning routine service to avoid overlap or missed details.

Heat Pump Inspection & Testing

If your heat pump isn’t working right and you’re not sure why, a thorough inspection is the only way to get real answers—guesswork just wastes your time and money.

Inspections are for the strange cases: the system cycles rapidly, your rooms are unevenly heated or cooled, or you hear odd clicking, popping, or hissing. Maybe the system smells musty or you’ve noticed ice buildup even when it shouldn’t be freezing outside. These are all symptoms we see when there’s trouble lurking deeper in the system.

What we test during an inspection:

- System startup sequence and shutdown behavior - Refrigerant charge and pressure balance - Electrical resistance and capacitor values - Defrost cycle timing and reliability - Airflow measurement through ducts and returns

We’ve uncovered everything from partially blocked ducts to hidden refrigerant leaks that other companies missed. A proper inspection goes far beyond a visual glance—it’s about measuring, testing, and confirming that every part does what it’s supposed to. If we find a problem, you’ll get a direct answer: repair it, replace it, or keep an eye on it.

Some homeowners start with Heat Pump Inspection & Testing when they’re not sure whether they need a repair, a full Heat Pump Installation & Replacement, or just a targeted Heat Pump Maintenance & Tune-Up. In any case, the inspection is your first step to real peace of mind.

Our Approach

We treat every heat pump call as if it were our own home on the line—no shortcuts, no “good enough” fixes, and no mystery charges.

Our process starts with real diagnostics. We don’t just swap parts; we explain what failed, why it happened, and what your options are. You get a clear plan for your system, whether it’s a quick tune-up, a part replacement, or a full install. We always lay out the risks of putting off bigger repairs versus biting the bullet now.

Every technician on our crew is trained to Silicon Valley’s tough building codes and has seen every weird failure mode these systems can throw at you. We’re careful with your house, clean up after ourselves, and keep you in the loop from start to finish—no high-pressure sales, just honest work.

We also believe in proactive care. If we see something during a Heat Pump Maintenance & Tune-Up that looks like it could cause trouble, we’ll tell you—before it turns into a late-night breakdown. That’s how we help you avoid those “how did it get this bad?” moments.
