Why trust SumZero for heat pump maintenance?

We’re heat pump specialists. Our certified team provides thorough, honest service focused on long-term efficiency and comfort for your home.

What happens if you find a problem during the visit?
We’ll show you what we found, explain your options, and provide a quote for any necessary repairs—no surprises, no pressure.
Does maintenance keep my manufacturer warranty valid?
Yes. Most manufacturers require annual or biannual maintenance to maintain warranty coverage. We document all service visits for your records.
Do you offer maintenance plans for heat pumps?
Yes. Our Comfort Club includes scheduled maintenance, priority service, and repair discounts—designed to keep your heat pump in top condition year-round.
Will maintenance help my heat pump last longer?
Absolutely. Routine service helps prevent breakdowns, reduces stress on components, and extends your system’s lifespan.
How long does a maintenance appointment usually take?
Most maintenance visits take 45 to 60 minutes, depending on system condition and accessibility.
Can regular maintenance lower my energy bills?
Yes. Clean components and efficient operation reduce energy use, which can help lower your monthly heating and cooling costs.
Why does my heat pump need two maintenance visits per year?
Because heat pumps run year-round for both heating and cooling, they experience more wear than traditional systems and benefit from seasonal checkups.
What’s included in a typical heat pump maintenance visit?
Our maintenance service includes checking refrigerant levels, cleaning coils and filters, inspecting electrical components, testing airflow, and verifying thermostat settings.
How often should I schedule heat pump maintenance?
We recommend scheduling heat pump maintenance twice a year—once before the heating season and once before the cooling season.
