How Are Heat Pump Systems Different?
Electric heat pumps offer an energy-efficient alternative to gas furnaces and air conditioners. They work differently than more traditional heating and cooling systems.
Heat pumps operate like air conditioners. They use refrigerant and a compressor to capture heat and transfer it to another location. In the summer, they capture heat from inside your home and transfer it outdoors.
In the winter, you switch a reversing valve and the heat pump captures heat from the outdoors and transfers it into your home.
Because they capture and transfer heat rather than create it, heat pumps are very energy efficient, costing you much less in energy than gas furnaces or boilers that burn fossil fuels to generate heat before transferring it.
Heat Pump Benefits
Heat pumps are a smart, energy-efficient solution for year-round comfort in the North Bay. Unlike traditional systems, they provide both heating and cooling, using less energy and lowering utility costs. Whether you’re upgrading your HVAC system or building new, here are some key benefits that make heat pumps a popular and eco-friendly choice.
Heat Pumps Are Energy Efficient
Energy efficiency is one of the most compelling benefits of a heat pump. Heat pumps use significantly less energy by transferring heat rather than generating it, helping you save money on utility bills all year while reducing environmental impact.
Heat Pumps Work in Cold Weather!
Modern heat pumps are highly efficient even in very cold climates. Advancements in technology, such as inverter compressors and enhanced vapor injection, allow them to extract heat from ambient air down to very low temperatures, often below 0°F (-18°C), making them perfectly suitable for our the North Bay climate.
Enjoy Fresh Indoor Air With a Heat Pump
Heat pumps often have advanced filtration systems that can remove more airborne particles, allergens, and pollutants than standard furnace filters. They also don’t produce combustion byproducts like carbon monoxide, contributing to healthier indoor air quality!
All-in-One Heating and Cooling
Heat pumps provide both heating in the winter and cooling in the summer, eliminating the need for separate furnace and air conditioning units. This streamlines installation, maintenance costs, and saves space.
Financial Incentives for Heat Pumps
Due to their energy efficiency and environmental benefits, California offers significant rebates and other financial incentives for installing heat pumps, making the initial investment more affordable. Your local utility company may also offer incentives to make the switch to heat pumps.
Heat Pumps Reduce Carbon Footprint
Because heat pumps are electric and highly efficient, they produce significantly fewer greenhouse gas emissions than fossil fuel-burning furnaces. As electricity grids become increasingly decarbonized with renewable energy sources, the environmental benefits of heat pumps will continue to grow.

If your heat pump isn’t performing like it used to, it may be time to schedule a professional inspection. Here are some common signs your system may need repair, addressing them early can help prevent bigger, costlier problems down the line:
- Struggles to reach the set temperature, if your heat pump runs constantly but never reaches the desired temperature, it could signal issues like a malfunctioning thermostat, refrigerant leak, or a failing compressor, each of which requires expert attention.
- Unexplained spike in energy bills, a sudden increase in your utility bill may indicate that your heat pump is working harder than normal to maintain comfort. This inefficiency could stem from dirty coils, airflow restrictions, or worn-out components.
- Uneven heating or cooling: if some rooms feel much warmer or cooler than others, your heat pump may be dealing with airflow problems, duct leaks, or sensor malfunctions that prevent even distribution of conditioned air.
- Unusual or loud noises: clanking, buzzing, or grinding sounds can suggest loose parts, debris in the unit, or internal damage. These noises shouldn’t be ignored, they often precede major breakdowns.
- Water leaks or drainage problems, if you see pooling water or signs of moisture near the unit, it could mean a clogged condensate drain line or frozen coils, both of which need immediate repair to prevent water damage and system failure.

Heat Pump Maintenance
Keeping your heat pump properly maintained throughout the year helps prevent unexpected breakdowns, improves energy efficiency, and extends the system’s life span. With a mix of DIY tasks and professional tune-ups, you can keep your heat pump operating smoothly and reliably in every season.
DIY Heat Pump Maintenance Tasks
- Clean or replace air filters: dirty filters restrict airflow and reduce efficiency. Check them monthly and clean or replace as needed.
- Keep the outdoor unit clear: remove leaves, debris, and snow from around the outdoor unit to allow proper airflow.
- Inspect and clean vents: ensure all indoor vents are open and unobstructed by furniture or rugs. Regularly clean them of dust.
- Monitor thermostat settings: make sure your thermostat is set correctly for the season and functioning properly.
Professional Heat Pump Maintenance Services
- System inspection: our licensed and certified technician will inspect electrical components, connections, and safety controls.
- Refrigerant check: your technician will check refrigerant levels and look for any leaks. We can typically recharge it the same day if you approve the additional service.
- Lubrication and cleaning: motors and moving parts are lubricated; indoor and outdoor coils are cleaned to maintain optimal efficiency.
- Test system performance: your Ongaro technician will verify that your system starts, runs, and shuts down properly, and that it’s delivering the right temperature output.

Why Ongaro & Sons for Heat Pumps
A heat pump is an electrical project as much as a heating project, and we hold both licences.
Schedule Service →HVAC and electrical in the same company
Heat pump retrofits routinely need panel capacity, a new circuit, or a load calculation before the equipment can land. Ongaro & Sons holds C-20 and C-10, so the panel work does not become a second contractor and a second schedule.
Mitsubishi Diamond Contractor Elite
The top tier of Mitsubishi Electric contractors, which is the line most often specified for North Bay retrofits where ducts are poor or absent.
Sized for design temperature, not for a brochure
Capacity falls as it gets colder. We size against the actual design temperature for your part of the county and specify backup deliberately, rather than discovering the shortfall in January.
We look at the distribution before we specify
A heat pump moves a larger volume of air at a lower temperature than the furnace it replaces. Ducts sized for the old equipment often need sealing or resizing, and finding that out afterwards is expensive.
Permits, Title 24 and the paperwork that follows
Changeouts require permits and documentation in all three counties. We handle them, and the record follows the house.

Read MoreFrequently Asked Questions
Are heat pumps energy efficient?
Yes! Heat pumps are one of the most energy-efficient HVAC options available. Because they move heat instead of generating it, they use significantly less electricity than traditional systems, especially in moderate climates.
Can a heat pump replace my furnace and air conditioner?
Absolutely. A heat pump can serve as both your heating and cooling system. In colder regions, some homeowners choose to pair a heat pump with a backup furnace in a dual-fuel system for maximum efficiency and comfort.
Do heat pumps work in cold climates?
Modern cold-climate heat pumps are designed to work efficiently even when temperatures drop below freezing. However, a supplemental heat source may be recommended in extremely cold areas.
How often should a heat pump be serviced?
We recommend scheduling maintenance at least twice yearly, ideally before peak heating and cooling seasons, to avoid costly heat pump repair.
