One of the most common questions we hear is, “What size AC unit do I actually need?” This is a very good question because the answer varies depending on your home’s needs. A professional AC company will help engineer the perfect size AC system for you, but you may want to get an idea for yourself. Here are a few guidelines you can follow when choosing the right size for your HVAC unit.
First things first, what sizes do AC units come in? Most central air conditioners come in a variety of sizes, and are measured by how fast they can cool in a unit called “tons.” Home air conditioners can range from 1.5-5 tons. Anything over five tons is not intended for residential use. If your home needs more than five tons, you’ll to install two three-ton units.
Installing the right size air conditioning unit matters. With AC, bigger is not always better. Electricity isn’t cheap, and energy conservation is more important than ever. You want to make sure your AC unit is working to save you money, not drive up your utility bill. A unit that’s too big will cool your home fast and then shut off, leaving a large amount of time for heat to creep back in. A unit that’s too small will be constantly trying to catch up to your preferred temperature. It’s important to get the size right.
You can calculate the exact size of the AC unit you need by using this equation:
((House square footage times 30, divided by 12,000) – 1.0) = Required Tonnage.
For hotter climates, subtract 0 instead of -1.
This,d of course, should all be verified with an HVAC repairman beforehand to ensure you’re getting the best fit for your home. Contact us today at Go Green Heating and Cooling for a free estimate.
Friendly, professional, reliable, and reasonable price. I had a great experience upgrading my attic insulation. We had good communication, they did the job in a timely manner, and they didn’t pressure me to add on more than I needed. Quick and easy.
Very pleased with Go Green! They were able to come out the same day I called and were very friendly, honest, and informative and did good work. Thanks Go Green!
Totally happy with my A.C. check today. Feared the worst but you guys really came through. You are now my go-to A.C. guys. Highly recommended!
Our technician, Mike was great! Went above and beyond to answer all my questions as well as doing a very efficient job.
5-star service all around from the initial consultation to the final install. Thank you for a flawless experience, Brandon Acosta!
After receiving a ridiculously high quote from the HVAC company sent out by our home warranty, my husband wanted a second opinion. Our technician Mike was thorough and honest about what needed repair. Not only was the diagnosis much simpler, so was the price. Mike got the repair done quickly and was very professional. We’ll definitely be calling Go Green again.
Such a professional process…from estimate through installation. The payment options were amazing. Brandon is terrific …explained everything from beginning to end. The technicians, knowledgeable, fast and thorough. Highly recommend Go Green!
