2023 is here, and for many Marin, Napa, and Sonoma county homeowners, that means setting some goals for the new year. Whether your goals are around fitness, family, home repairs, finances, or something else, this the perfect time of the year to ensure you are setting yourself up for successfully achieving your resolutions. If your New Year’s resolution is to save energy or lower home expenses, energy efficient HVAC can help. We are going to review how upgrading to an energy efficient HVAC system can mean big savings for your home’s energy usage and your pocketbook.

What is Energy Efficient HVAC?

Do you know what consumes the most energy in your home? It’s your HVAC system. The average household spends more than $2,200 a year on energy bills, with nearly half of this going to heating and cooling costs (EnergyStar).

An efficient HVAC system is cost-effective when the lifetime energy savings (from avoided energy costs over the life of the product, discounted to present value) exceed the additional up-front cost (if any) compared to a less efficient option ( To put this simply, compared to standard units, energy-efficient HVAC uses less energy and costs less to operate without affecting performance and comfort.

An energy efficient HVAC system can be determined by two things:

SEER: Seasonal energy efficiency ratio or SEER, measures an air conditioner’s cooling output ratio, divided by the energy it uses in watt-hours. SEER ratings for modern air conditioners range from 13 to 21. The higher the number, the more efficient the cooling appliance will be. The U.S. Department of Energy enforces minimum SEER requirements that differ by geographical region.

A SEER ratio is calculated over an entire cooling season using a constant indoor temperature and a variety of outdoor temperatures ranging from 60 degrees to 100 plus. This is how it simulates a typical season.

Keep in mind that SEER ratio is a maximum efficiency rating, like the miles per gallon for your car. Say your car gets 34 miles per gallon on the highway; however, if you’re stuck in stop and go traffic it’s a lot less efficient. The same goes for your air conditioner. If your SEER ratio is 20, that’s the maximum efficiency and it could be lower depending on conditions.

AFUE: AFUE, annual fuel utilization efficiency, refers to the percentage of heat used by a furnace or boiler converted into heating your home. This is a measurement of how well your furnace uses fuel to heat your household. The higher the rating, the more efficient your heating unit.

A unit that has above 95 percent AFUE is converting most of its fuel into heat. Simply put; if you have a furnace with an 80 percent AFUE rating, you’re losing 20 cents of every dollar of your heating bill, or $20 for every $100 you spend.

The above is just an example. Your furnace probably has an AFUE rating of 78 percent or higher, unless you have an old furnace. In 1992, the U.S. Department of Energy established new manufacturing standards for furnaces, requiring them to be at least 78 percent efficient. That number rose to 80 percent in 2013, and most modern high-quality units hit 98 percent efficiency (

How Energy Efficient HVAC Can Help you Save Energy and Money

If you don’t have an energy efficient HVAC system in your home, chances are it is costing you… quite possibly a lot.

If your outdated HVAC system is causing you to call for repairs or servicing several times a year, it might be time to consider an upgrade. A new system can help you enjoy more consistent heating and cooling throughout your home and lower your utility bill. Energy efficient HVAC systems have several other benefits as well:

  • Increased comfort because energy efficient units produce more even heating and cooling, help maintain a constant temperature in every room in your home, provide consistent levels of airflow, and have superior humidity control.
  • Lower noise level due to newer HVAC units being designed with sound-absorbing materials and technology.
  • Better environmental impact because energy efficient systems use less electricity and burn less fuel than older systems. High efficiency systems use up to one-third less fuel than older models, which means they help conserve more of our natural resources.

Do you like to keep your home warm and cozy? Do you like to lower the temperatures in your home and keep it cooler while you are sleeping? Did you know that there is actually a recommended temperature range that you should keep your home at? Try to take a guess at what that range is. Do you think you have it? The truth is, most people keep their homes much warmer in the winter months and much cooler in the summer months than they really should. So, what’s the ideal temperature for your home?

What’s the Ideal Temperature for Your Home?

We all find different temperatures to be comfortable throughout our homes, but most Marin, Sonoma, and Napa County homeowners want to find a balance between comfort and higher energy bills. By keeping your home at the temperatures we review below, you can save as much as 10% a year on heating and cooling expenses. provides the below recommendations.

Depending on the season, the ideal house temperature for both comfort and efficiency is between 68° to 78°F.

You can save energy in the winter by setting your thermostat to around 68°F while you're awake and setting it lower while you're asleep or away from home. To stay comfortable and save money in the warmer months, the U.S. Department of Energy recommends setting your thermostat to 78°F when you are home and higher while you are away. While 68°F may seem much too cold for your home and 78°F may seem way too warm, these temperatures have proven to cut energy costs and still keep most people comfortable.

During winter, the lower the interior temperature, the slower the heat loss. So the longer your house remains at the lower temperature, the more energy you save, because your house has lost less energy than it would have at the higher temperature. The same concept applies to raising your thermostat setting in the summer; a higher interior temperature will slow the flow of heat into your house, saving energy on air conditioning.

Change your temperature settings when you sleep and are away from the home.

As referenced above, you should change your home’s temperatures when you are away or sleeping. If you have a programmable thermostat, you can easily set day and time ranges, so it can change the settings for you. This will help you avoid any discomfort by returning temperatures to normal before you wake or return home. The Department of Energy suggests changing your normal temperature settings by 7° to 10°F while you are away from the home.

What is the best temperature for sleep?

When it comes to the ideal temperature for your home, as we said, this varies by time of year, time of day, and if you are actually there or not; however, did you know that there are also scientific reasons why you should sleep at a certain temperature? It’s true, changing the temperatures at night won’t just save you money, it can lead to a much better night of rest as well.

The suggested bedroom temperature is between 60°F and 67°F for optimal sleep ( When trying to fall asleep, your body temperature decreases to initiate sleep and the proposed ideal temperatures can help accelerate this. If your room is cool, rather than warm, it will be much easier to shut your eyes for the night. Keeping the temperature while you sleep either too hot or too cold while you are trying to catch some shut-eye may affect the drop in your body’s internal temperature and cause you to have an anxious sleep.

Did you Guess the Right Ideal Temperature for Your Home?

Remember when we had to guess the ideal temperature range above, did you get it right? The truth is, most people don’t really think about saving money when it comes to heating and cooling their homes, they just want to be comfortable, but by giving the recommended temperature range a try you could see some major rewards in your wallet.

Have you even been woken up in the middle of the night because you are too cold? What about getting out of bed because you are much too hot? Both of these things can be directly caused by your thermostat. Your Marin, Sonoma, or Napa County home’s thermostat controls your home and family’s comfort level more than you may even realize. There are indications that it is time to your replace your thermostat, and they should not be ignored. Is your thermostat in need of replacement?

Is Your Thermostat in Need of Replacement?

Having the right and a functional thermostat, can save you around 10% a year on heating and cooling costs, so it is important to know if your thermostat is in need of replacement.

Around 90% of American households have HVAC, and, as stated above, the thermostat is one of the key components to a HVAC system. Your thermostat is a regulating device component, of your HVAC. To put it simply, your HVAC’s thermostat is the central control center of your home’s heating and cooling system. It's the thing that determines when and how much hot or cold air to deliver throughout your home.

Because we know how important it is for you and your family to enjoy the temperatures within your North Bay Area home, we are going to review some signs that your thermostat is in need of replacement.

  • Thermostat Will Not Respond or Adjust: An easy way to tell if your thermostat needs replaced, is if it stops changing settings or will not respond when you are adjusting it. When you adjust temperature settings on your thermostat, it should promptly respond to those changes. If your HVAC system doesn’t come on immediately when you make adjustments, there is likely an issue with the thermostat.
  • Outdated and Past its Prime: As with everything, your thermostat can become outdated, with a typical lifespan of around a decade. If you know yours is nearing the end of its prime, it could be time to replace it. If you have a standard thermostat, think about upgrading to newer technology. You can save at minimal 10% a year on heating and cooling costs by having a programmable thermostat. This type of thermostat allows you to adjust the times you turn on the heating or cooling in your Novato home by having a pre-set schedule.
  • HVAC System is Erratically Turning Off and On: If you have noticed that your HVAC system has starting randomly turning off and on, with what appears to be no reason at all, your thermostat could be in need of replacement. It is very likely that the thermostat has a problem if your HVAC system has stopped taking the thermostat cues. The wiring inside your thermostat can become damaged or frayed, or there could be another issue.
  • Incorrect Temperatures Displayed: If your home’s thermostat is not reading the temperature of your home correctly, that can make for a less than desirable and uncomfortable environment. If you notice that your home feels much warmer or cooler than the thermostat is indicating, there could be a problem. To check whether the temperature is correct, you can test the thermostat’s reading with a portable indoor thermometer.
  • Inconsistent Temperatures: If your thermostat needs replaced, it may start having a difficult time maintaining settings and temperatures, as mentioned above. If you have noticed that the temperature in your home is continuously changing for no reason and with no warning, your thermostat could be going bad. Keep an eye on it and if it continues to happens, contact a local HVAC professional to help you diagnose the issue.


It’s important to note, for all of the issues above, if your thermostat runs on batteries, the first step to troubleshooting any issue, should be to replace the batteries with a new. If that doesn’t work, your thermostat is likely in need of replacement.

Your North Bay Area home’s thermostat is key to keeping you and your family comfortable all year round. If you suspect yours needs replaced or have another issue with your HVAC system, call in a local HVAC professional.
