Back in the “good old days,” homeowners turned on a ceiling fan, grabbed a bag of ice, and cooled down the old-fashioned way. Thankfully, modern technology makes it much easier to cool down—all it takes is the push of a button on your thermostat!

But, how do you know if your air conditioner is working at its best for your home? Just because you don’t hear or see any problems with your AC unit doesn’t mean it’s operating efficiently—you may not even notice there are problems until you get your energy bill for that month.

In this article, we’ll talk about what makes some air conditioners more efficient than others, which models on the market today are the best choice for better energy efficiency, and why you should have a professional technician from Bob’s Heating & Air Conditioning help improve your home!

What is SEER and why does it matter?

You may have seen this four-letter acronym before when looking at air conditioners and heat pumps online. It’s important! SEER stands for “Seasonal Energy Efficiency Rating,” and it refers to this ratio:

the cooling output of an air conditioner over a typical cooling season
the energy it consumed in Watt-Hours

The higher the SEER rating, the more energy efficient the unit is. These days, the minimum standard SEER rating for new air conditioners is a 13. Many air conditioners on the market today have a SEER rating within the range of 13-21. It’s important to note the the SEER rating is the maximum efficiency rating, much like a car’s miles-per-gallon rating—you might not reach that exact efficiency under certain conditions, much like your vehicle will have a lower MPG going uphill than on a level road.

To put it simply, the less energy your AC unit uses, the higher its SEER rating. This translates into lower utility bills for you, which means your wallet will thank you at the end of the month! When you’re shopping around for a new air conditioner, keep the SEER rating in mind, but don’t forget about other important factors to consider, such as system size, the type of system, and what your geographic area needs are. An AC professional—like those here at Bob’s—can help you find the right air conditioner for your home. Call us today for a free in-home estimate on a new energy-efficient cooling system.

How these systems can improve your home

Most air conditioners should be replaced after 15-20 years—and that’s only if the unit has received regular maintenance. If you’ve neglected your HVAC system for years at a time, you may experience more breakdowns or hidden problems, meaning that you may have to install a new unit even sooner.

Regular maintenance is the key to a better AC unit—you wouldn’t forget to take your dog or cat to the groomer or veterinarian for years at a time, so why treat your home units poorly? The more care and attention it receives, the better it performs.

Next time you’re taking Fluffy to the groomer, think about your home’s cooling and heating systems and consider scheduling a tune-up with Bob’s Heating & Air Conditioning!
