Reliable Heat Pump Maintenance Services in Phoenix
Day & Night Air Conditioning, Heating, & Plumbing keeps your heat pump maintenance on track in Phoenix, AZ.

Homeowners across Maricopa County, from the Willo Historic District to the foothills of Piestewa Peak, have trusted us since 1978. Our BBB A+ rating shows our outstanding customer service. We dispatch NATE-certified technicians who document every visit, so your manufacturer’s warranty stays intact. Book your Day & Night heat pump tune-up online or call us.
What Is the Best Time to Book a Heat Pump Tune-Up in Phoenix?
The best time to book a heat pump tune-up in Phoenix is twice a year, once before each season. Because a heat pump here cools all summer and heats in winter, one visit a year is not enough. The U.S. Department of Energy also links a system’s efficiency to regular upkeep.
Book the first tune-up in early spring, before cooling season starts. This is the big one. It gets your system ready for months of hot afternoons, when a weak unit is likely to quit.
Book the second in the fall, before you switch over to heat. A fall check ensures the heating side and reversing valve are ready for cooler nights.
You can also add another check after the monsoon season. Blowing dust and storms leave grit on the coil and can damage electrical parts. A post-monsoon check catches damage before winter.
Simple Heat Pump Maintenance You Can Do Yourself
You can change filters as needed and rinse dust off your unit between professional visits. These simple DIY heat pump maintenance habits help your system handle the Phoenix dust and heat. Here is what you can do.
- Change the filter often. Swap or rinse the air filter about once a month during heavy cooling, since Phoenix dust clogs it fast.
- Keep the outdoor unit clear. Pull weeds and clear leaves and debris from around it, especially after a dust storm.
- Rinse off the dust. With the power off, gently hose desert dust from the outdoor unit so air can move freely.
- Leave the vents open. Keep indoor vents open and clear of furniture and rugs. That way, air flows the way it should.
- Watch the drain area. Look for water pooling near the indoor unit. Keep that spot clear and dry.
- Set steady temperatures. Hold the thermostat at steady settings instead of big swings, which is easier on the system.
- Report small warning signs. Tell us if you notice weak airflow, a new noise, or a jump in your power bill.
Leave the deeper work to us. Refrigerant, electrical parts, and the reversing valve need tools and training. Those are best left to a professional.

Heat Pump Coil Cleaning for Desert Dust
Heat pump coil cleaning removes desert dust that settles on your coils and reduces performance. Your system has two coils, one outside and one inside, and both need clean surfaces to move heat. In Phoenix, fine blowing dust and monsoon grime coat the outdoor coil fast. When a coil is blocked, heat cannot escape properly. The system runs longer and hotter to reach the same temperature. We clean both coils during a tune-up, so your system cools with less strain. Get an instant quote for a tune-up.
Refrigerant Charge Check and Leak Inspection
A refrigerant charge check and leak inspection make sure your heat pump has the right amount of refrigerant to move heat. A heat pump does not burn fuel. It moves heat with refrigerant, both when cooling and when heating. As the refrigerant charge drops, the system loses cooling power. The indoor coil can ice over, and the compressor has to work harder to keep up. Left alone, that strain is one of the most expensive ways a heat pump can fail. During a tune-up, we measure the charge and check for leaks.
Reversing Valve and Defrost Testing
Reversing valve and defrost testing are heat pump-specific checks. The reversing valve is the part that switches a heat pump between cooling and heating by reversing the direction the refrigerant flows. The defrost cycle clears frost off the outdoor coil on cold mornings. If the reversing valve sticks, the system can get stuck in one mode and blow cold air when you want heat. If the defrost control fails, the outdoor coil can frost over in winter. We test both during a tune-up, so your system switches modes cleanly.

The Benefits of Regular Heat Pump Maintenance
Regular heat pump maintenance helps your system run efficiently, last longer, and break down less often. Here is what you get.
Lower Energy Bills.
A clean, properly charged heat pump uses less power to reach your set temperature. Over a Phoenix cooling season that runs for months, that steady efficiency adds up to real savings on every monthly utility bill.
Fewer Breakdowns.
Most failures start as small, fixable problems that a technician can catch early. A tune-up replaces worn parts and tops off low refrigerant before they cause trouble, so you are far less likely to lose cooling on the hottest afternoon of the year.
A Longer-Lasting System.
Heat, dust, and constant runtime steadily wear down a heat pump in the desert. Regular care eases that strain and keeps major components in good shape. It helps your system reach its full service life instead of failing years early.
Warranty Protection.
Many manufacturers require documented annual maintenance to keep the warranty valid, and a lapse can leave you paying for covered repairs. Our regular tune-ups give you the service record you need to protect that coverage.
Cleaner Indoor Air.
Every tune-up includes a fresh filter and a coil cleaning, the two places dust and buildup collect most. Cleaner surfaces mean cleaner airflow moving through your home, which matters during the dusty, allergy-heavy stretches of the year.
Steady Comfort.
A tuned heat pump holds the temperature you set, with fewer hot and cold spots from room to room. Whether it is cooling through a hot afternoon or heating on a cold winter night, the whole house stays more even and comfortable.
Our Heat Pump Tune-Up Process
Our heat pump tune-up process is easy on you and thorough on your system. You know when we are coming, what we check, and what we find. Here is how a visit goes.
We Confirm Your Window
You get a scheduled appointment window and a courtesy heads-up before we arrive, so you never have to wait or wonder when someone will show up. You can plan your day around a clear time instead of a vague all-day window.
We Arrive on Time and Protect Your Home
Our trained technicians arrive within the scheduled window, treat your space with care, and keep the work area clean from start to finish. We respect your home like it is our own and leave it exactly as we found it.
We Run the Full Inspection
We work through our complete heat pump maintenance checklist, point by point. We inspect and tune the thermostat, indoor and outdoor coils, refrigerant charge, electrical components, condensate drain, and controls, so nothing gets missed.
We Clean and Calibrate
We clean the coils, clear the condensate drain, tighten loose electrical connections, and calibrate the thermostat for accurate readings. With dust cleared and settings dialed in, the system runs the way it was built to run and uses less energy.
We Test Both Modes
We run the heat pump in cooling and then in heating, taking a temperature-split reading in each mode to confirm it moves heat correctly both ways. This is the step that proves your system is ready for the summer and the cool nights that follow.
We Review What We Found
Before we leave, we walk you through exactly what we found, what we did, and any repairs worth considering, with no pressure to decide on the spot. We answer every question so you understand your system and know where it stands.
Save More with a Heat Pump Maintenance Plan
You can save more on heat pump maintenance with a plan that bundles the year’s tune-ups together. Our VIP Club is built for exactly this.
A VIP Club membership includes two seasonal tune-ups a year, priority access to emergency service, and discounts on repairs. Priority scheduling is most important in peak summer, when everyone needs service at once. We place our members at the front of the line.
The plan also provides a documented service record to help keep your manufacturer warranty valid. If a tune-up reveals a larger repair, our financing options can spread the cost.

Frequently Asked Questions
Do I still need a tune-up if my heat pump seems to be working fine?
Yes. A heat pump can lose refrigerant, build up dust, or wear down parts while still running fine. You often will not notice until it quits on a hot day. A tune-up catches those quiet problems early, while they are cheap to fix.
My heat pump has never been serviced. Can you still tune it up?
Yes, and it is worth it. A system that has never been serviced usually has built-up dust, a dirty coil, and parts that have drifted out of spec. The first visit takes a little longer because there is more to clean and check. But it often makes a big difference in how the system runs.
How long does a heat pump tune-up take?
Most tune-ups take about 60 to 90 minutes. The exact time depends on your system and how easy it is to reach. An older or neglected unit, or one in a tight spot, can take a bit longer.
What happens if you find a problem during my tune-up?
We show you what we found and give you an upfront price to fix it. Still, the choice is always yours. There is no pressure to say yes on the spot. If it is a larger repair, financing is available to help manage costs.
