Positive Impacts

  • Filtration System: Many modern air conditioning systems are equipped with air filters that are designed to capture dust, pollen, mold spores, and other types of debris. This helps to enhance air quality by removing airborne pollutants and allergens from inside the home.
  • Humidity Control: Air conditioners often have dehumidifying functions that help control indoor humidity levels. This will help to inhibit the growth of mold and mildew.
  • Ventilation: Air conditioners have the ability to circulate and filter air throughout the entire indoor space. This consistency helps to prevent stagnant air which minimizes the concentration of allergens or pollutants.

Negative Impacts

  • Condensation & Mold Growth: In some conditions, air conditioners can contribute to moisture buildup (if not properly maintained). Excessive condensation in air ducts or cooling coils creates an environment conducive to mold growth which has the potential for mold spores to be released into the air.
  • Airborne Chemicals: Some AC units, particularly older models, may emit low levels of VOCS (volatile organic compounds). This depends on the type of refrigerant that is used.
  • Inadequate maintenance: Poorly maintained ACs units can circulate pollutants or allergens throughout an entire home. Without regular tune-ups, air conditioners can compromise air quality.

What Are The Common Pollutants and Allergens That Can Be Found in Air Conditioning Systems?

Air conditioning systems can hold on to various pollutants and allergens that can greatly affect the indoor air quality of a home including:

  • Dust: Dust particles can accumulate in air filters, ducts, and coils, leading to reduced system efficiency and the potential release of airborne particles into indoor spaces.
  • Mold & Mildew: The potential for mold and mildew build-up is a possibility when condensation sits within those AC systems. Mold spores can be released into the air and cause respiratory health risks.
  • Bacteria & Viruses: Moist areas are also a site for bacteria and viruses to thrive. Microorganisms may be found inside drip trays or cooling coils which can contribute to bacteria and viruses being circulated in the air.
  • Pollen: Outdoor air filled with pollen can infiltrate an AC unit. Once inside, pollen can collect in filters and ducts which can trigger allergic individuals.
  • Pet Dander: Airborne particles of skin, hair, and saliva, from our pets can also be circulated through the air, especially if homeowners are not changing air filters regularly.
  • VOCs: As mentioned before, VOCs can be emitted by some cooling systems depending on their use of coolant. Prolonged exposure to these can become a health risk.
  • Tobacco Smoke Residue: Residue from tobacco smoke can also accumulate inside an air conditioner and pose a risk to non-smokers. Regular cleaning and maintenance is essential to reduce the presence of these particles.
  • Pesticides & Chemicals: Chemicals found in household cleaning products or pesticides can also be drawn into AC units. Their accumulation can impact the air quality inside the home.

Rearrange the Furniture

A simple bout of feng shui can lead to big energy savings, because rearranging the furniture in your home can actually make it warmer or cooler! If you’re looking to create a cooler home and a happier AC unit, all you have to do is strategically place your furniture out of reach of direct sunlight. This reduces radiant heat absorption and prevents your system from having to work as hard to keep the home chilled throughout the warmest months of the year.

Utilize Shade

Pay attention to those sunny spots in and around your home. This tip coincides well with our previous suggestion—once you rearrange your furniture, you should also ensure that you are properly creating shade and reducing the need for extra cool air in certain areas of the home.

This includes but is not limited to:

  • Installing blinds or shades on the windows
  • Hanging curtains
  • Planting trees in the front or backyards to break up direct sun exposure

This purposeful positioning allows your home to be shielded from those strong (and hot) UV rays.

Frequently Asks Questions about Saving Energy with Air Conditioning Units

Is it cheaper to leave the AC on all day or raise the temperature while you’re away?

There is some debate here, but it is generally more energy and cost-efficient to raise the temperature while you’re away rather than leave the AC unit working all day long. When your home is empty—especially during longer periods like vacations—there’s no need to maintain lower temperatures.

What is the best or most efficient temperature to set your AC to?

The answer to this might hurt those of you who love to set your thermostats at an extra cool 65°F—but in actuality, the most efficient temperature to set your unit to in hot weather is 78°F. However, this may be too warm for most, so we recommend that you try a happy medium around 75°F to minimize energy consumption without sweltering.

Does auto-mode save electricity or energy?

Yes, the auto-mode on your thermostat will absolutely save both electricity and energy. When your system is in “auto” mode, the thermostat’s fan setting will automatically adjust based on the temperature setting you’ve selected. When the desired temperature is reached, the fan will shut off and conserve electricity (and energy).

Furnaces provide powerful heat for your home during the coldest months of the year, while heat pumps offer versatile heating and cooling from a single piece of equipment. But what’s the best way to heat your California home—a furnace or a heat pump? You’re in the right place to find out.

As your friendly neighborhood HVAC experts here at Cencal Mechanical Heating & Air, we’ve performed installations for new heat pumps and furnaces throughout the Central Valley. Let us help you make an informed decision about your new home comfort equipment by comparing the pros and cons of each system below.

What’s the Difference Between a Heat Pump and a Furnace?

Think of a furnace as a fireplace that’s been upgraded for the 21st century, and a heat pump as a magic box that can make both hot air and cold. Furnaces burn fuel to create heat, typically using natural gas, propane, or oil. Heat pumps, on the other hand, use electricity to move heat from one place to another—from the outside to the inside in the winter, and vice versa in the summer. That’s right; heat pumps can also act as air conditioners in those hot California summers!

But while heat pumps offer exciting capabilities to homeowners, that doesn’t mean furnaces are obsolete. Figuring out what type of heating equipment is best for you comes down to your comfort preferences, fuel availability, your budget, and more.

Heat Pumps


  • More efficient than the majority of central furnaces (especially older ones)
  • Use electricity instead of burning fuel (eliminating carbon emissions)
  • New heat pump installations may make you eligible for rebates in California


  • Slower to provide heat than central furnaces
  • Using electricity to produce heat typically costs more than natural gas
  • Not as energy efficient in particularly cold climates

Are Furnaces or Heat Pumps More Energy Efficient?

In terms of overall energy efficiency, heat pumps take the trophy over central furnaces. They move heat instead of generating it, which uses less energy. In the right conditions, a high-quality heat pump can transfer over three times as much energy as it uses.

Furnaces, however, are catching up—many new models can be up to 95% efficient. It’s also important to note that some heat pumps have supplementary systems like electric heating elements that they use to produce heat during particularly cold periods, where there is not enough heat available outdoors to transfer into your home. This generally isn’t a problem in the Central Valley—but during freak cold snaps, relying on these supplementary systems can make a heat pump less efficient.

Comparing the Costs of Furnaces & Heat Pumps

Installation Costs

When it comes to upfront costs, furnaces tend to be less expensive. A new heat pump from a quality brand usually costs about two-thirds more to install than a comparable central furnace, including parts and labor.

However, the exact costs of installing a new furnace or heat pump will depend on many factors, including:

  • The condition and complexity of your home’s existing ductwork
  • The quality of your insulation
  • The heating capacity required by your home
  • The accessibility of the installation location

Long-Term Operating Costs

The lower operating costs of a heat pump can help offset their initial costs over time, especially with the rising cost of fossil fuels. For example, switching from a gas furnace to a heat pump has the potential to decrease your monthly heating costs by over 30% under ideal circumstances—but it’s critical to note that this number can fluctuate significantly depending on current energy prices and climate conditions.

Generally, however, California’s mild climate allows heat pumps to function effectively in the winter and provide consistent savings—especially over older central furnaces. Yes, if you were living in the ice-cold corners of Alaska, a heat pump might struggle to keep up with the extreme cold. But here in the Golden State, where winters are mild, a heat pump can provide comfortable and efficient heating.

When to Buy a Heat Pump or Central Furnace for Your California Home

Given the above, there are distinct circumstances when it makes more sense to invest in either a heat pump or a central furnace. Here are some points to help you make your decision:

Consider a Heat Pump If…

  • You want to reduce your carbon footprint: Remember, heat pumps don’t burn fossil fuels like central furnaces do.
  • You’re okay spending more up front for long-term savings: If you’d rather pay more now and enjoy lower monthly utility bills, a heat pump could be the answer.
  • You’re confident that you won’t face extreme cold anytime soon: This should be true for pretty much everyone in California’s Central Valley—but if you’re really worried about cold snaps, you might be more comfortable with a central furnace system.

Consider a Central Furnace If…

  • You have access to natural gas: If your home is already connected to a natural gas line, you’ve got access to a fairly efficient fuel source, and the money you’d save each month with a heat pump might not justify the switch over your equipment’s projected lifespan.
  • You pay a high rate for electricity: The downside to not using fossil fuels is that heat pumps can be expensive to run in homes that pay high electricity rates. Since California’s electricity prices are higher than the US average, it’s worth checking with us to make sure a heat pump will be cost-effective for you before buying one.
  • You’re worried about record-breaking winter temperatures: Weather can be unpredictable, so if you want a heating system that can deliver reliable comfort in unexpectedly cold conditions, a central furnace may give you more peace of mind.

Other Considerations When Buying New Heating Equipment

How Old Is Your Current Heating System?

Most furnaces become significantly less efficient after 10 years and start to experience consistent performance issues around age 15 or so. If your system is on its last legs or doesn’t heat your home effectively, it might be time to say adios and invest in a new system.

What Kind of Maintenance Will You Do?

Both heat pumps and furnaces require regular maintenance to operate at their best. Furnaces need annual heating tune-ups, while heat pumps should be checked twice a year due to their dual heating and cooling functions (once in the spring and once in the fall).

Can You Qualify For a Rebate?

Heat pump buyers who purchase through Cencal Mechanical can save up to $3,000 on a new heat pump, with up to $750 in utilities, $2000 in tax credit, and $250 instate rebate. We also include 3 years of free maintenance when you get a new heat pump installed.

Extra Tips for Maximizing Your AC Efficiency

  • Using proper thermostat settings: Set your thermostat to a comfortable temperature that isn’t too low, as each degree can save energy and reduce costs. Consider using a programmable smart thermostat to adjust temperatures automatically when you’re away or asleep—this can reduce energy waste and save you up to 10-20% on your heating and cooling costs.
  • Utilizing fans and natural ventilation: Use ceiling or portable fans to help circulate cool air and create a wind-chill effect, making your home feel cooler without lowering the thermostat. Open windows in the evening to let in cool air and close them during the day to keep heat out.
  • Insulating your home: Proper insulation helps keep your home cool in summer by reducing heat transfer between the indoors and outdoors. Insulate your attic, walls, and floors to maintain comfortable temperatures and lower your energy bills.
  • Installing energy-efficient windows and doors: Energy-efficient windows and doors minimize heat gain and loss, making it easier for your AC to maintain a comfortable temperature. Look for double-pane windows with low-E glass and well-sealed doors to improve your home’s energy efficiency.

Staying cool in the spring and summer is a challenge for many Central Valley residents, since running the air conditioner constantly can quickly become expensive. What many people don’t know is that supplementing your AC with a heat pump can actually bring your cooling costs down significantly, making it much more cost-effective to stay comfortable throughout the hottest months of the year.

Modern heat pumps use less energy than central air conditioners, but can still reduce your indoor temperature significantly—letting you save the AC for those hot days when you really need it (and save money in the long run). Learn more below from our experienced HVAC technicians about how you can use a heat pump to make your home more comfortable and energy-efficient at the same time.



How Does a Heat Pump Work?

Like central air conditioners, heat pumps use refrigerant to move heat from one area to another. Unlike air conditioners, however, heat pumps can also reverse this process to move heat from the outside into your home and raise the temperature, which means they provide both heating and cooling capabilities.

When your heat pump is in cooling mode, it goes through the following steps:

  • Refrigerant enters the compressor as a low-pressure gas
  • The compressor squeezes the refrigerant to raise its pressure and increase its temperature
  • The refrigerant enters the condenser, where it releases its heat to the outdoors and becomes a high-pressure liquid
  • The liquid refrigerant moves to the expansion valve where its pressure is released—causing its temperature to drop even further
  • The refrigerant reaches the evaporator where it absorbs heat from inside the home and vaporizes into a low-pressure gas
  • As a low-pressure gas, the refrigerant enters the compressor and begins the cycle again

Why Heat Pumps Use Less Energy than Air Conditioners

The steps described above are the same basic tasks that your central air conditioner performs—but heat pumps use less energy. Here’s why:

  • Using a heat pump to provide heating and cooling with the same system uses much less energy than switching back and forth between separate heating and cooling equipment. This is because most of the energy furnaces and air conditioners use is spent while they’re starting up.
  • Heat pumps are often designed with variable-speed compressors, allowing them to operate at lower speeds than air conditioners. This means they can more accurately match their output to your home’s cooling needs and reduce energy waste.
  • Our heat pumps also come with WiFi-enabled smart thermostats, which can further enhance energy efficiency by automatically adjusting your equipment to maintain optimal comfort levels in your home.

The Benefits of Heat Pumps for Homeowners

The convenience and energy efficiency heat pumps offer results in numerous benefits for homeowners. Here are a few of the clearest:

Reduce Your Carbon Footprint

High-efficiency heat pumps use up to 60% less energy than conventional central HVAC systems, according to the California Energy Commission. This translates into a reduction of over 5,500 lbs in greenhouse gas emissions every year.

Lower Your Monthly Utility Bills

Using less energy also means paying less each month to cool your home. Based on the numbers above, an average California homeowner could save $1000 on cooling annually with a heat pump—or ~$83 per month. Bear in mind that savings for individual households will vary depending on specific usage habits.

Qualify for Rebates & Incentives

Heat pumps qualify for several rebates and incentive programs that can offset their installation and maintenance costs. For example, you can get a 30% federal tax credit up to $2000 for new heat pump installations that meet the requirements of the Consortium for Energy Efficiency (CEE).

Heat Pump Best Practices

High-efficiency heat pumps provide comparable cooling power to most central air conditioning systems while offering better energy efficiency, so replacing your AC with a new heat pump can be a smart move. Adding a heat pump and keeping your air conditioner is also an option—using the heat pump to supplement your AC on the hottest days of the year is a much more efficient way to cool off than simply pushing your air conditioner to its limits.

Here are some other tips for making the best possible use of your heat pump:

Usage & Maintenance Tips

  • Combine your heat pump with a WiFi-enabled smart thermostat to ensure its output is always consistent with your cooling needs (our heat pumps come with these by default).
  • Clean or replace your heat pump’s air filter on a monthly basis.
  • Keep your doors and windows closed when running your heat pump to prevent hot air from entering.
  • Use curtains to stop direct sunlight from entering your home through windows and warming the interior.
  • Have your heat pump professionally serviced twice a year (we recommend once in the spring and once in the fall). Our team can diagnose any problems with your heat pump and present you with solutions to ensure its energy efficiency throughout the year’s warmest months.

Using a Heat Pump for Cost-Effective Cooling

While heat pumps aren’t normally effective replacements for central air conditioners in California, they make an excellent way to reduce the amount of energy it takes to cool your home on all but the hottest days of the year. The savings a heat pump provides can easily pay off their installation costs in just a few years, providing you and your family with more income each month.
