Air conditioning tips keep you from sweating repairs
People have been beating the heat since 1926, thanks to Willis Haviland Carrier, an American engineer, who invented modern air conditioning for homes. Fast forward 89 years later and more than two-thirds of all U.S. homes have air conditioning, spending more than $11 billion annually in cooling costs.*
There’s a reason why we’re spending so much. Here in hot South Texas, the HVAC (heating, ventilation and cooling) system makes up almost 60 percent of your energy bill during the summer. If you’re keeping your thermostat set to an ideal temperature like 78 to 80, your system will run on average 12 hours out of a 24-hour period. But if the temperature outside is more than 20 degrees higher than your thermostat setting, i.e. thermostat is at 78 and heat index is 102, then your air conditioning system will run even more.
To help your HVAC system run as efficiently as possible, make sure you do regular maintenance. After all, it’s been working hard for you.
If you neglect your system, you may have to call a professional. But before you do, here is a list of common air conditioner problems and some troubleshooting tips.

Good tips, this is very helpful, especially who lives in hot places like Texas. I truly agree, efficiency of your HVAC is how you regularly maintain them. http://coolingforless.com/
Wow, I had no idea that the HVAC system takes up 60% of my energy bill during the summer! That being said, you talk about how keeping the thermostat at an ideal temperature can help you regulate this system and help you to be more efficient, and I definitely agree. Additionally, I think that doing regular maintenance and cleaning will help you to ensure that everything in the unit is working properly and efficiently, too. Thank you for sharing!
Thank you Lauren! We appreciate you taking the time to comment. We’re glad to know the information we are sharing is helping. Have a great weekend but stay safe, lots of rain on the way. -Albert Cantu
Thank you for your feedback we really appreciate it. We love it when we can offer information to our customers that can make a difference in their day to day life around electricity. Have a wonderful weekend. -Albert
My husband and I recently moved into a new home and we have been having a few issues with our AC. It doesn’t feel like it is cooling the whole house and it is costing us a lot more money than we expected. I am thinking that there is a repair that needs to made to the sensor or the coolant so we will have to look into that. Thank you for sharing these insights, they will definitely help!
Thank you Avery for your feedback, we appreciate that. Sounds like you might have a number of issues. You’ll know you have a freon leak because your system will not blow cool air and the freon pipe will literally ice over. If you see ice that’s a telltale sign you’ve got a leak. Like my Facebook page “You Can Too with Cantu” and watch the Dan Chambers segment. He was having issues like you, turns out it was with the duct work not being engineered correctly. He had uneven cooling in the house. Keep us posted on what you find. Thank you. Enjoy the rest of the holidays. -Albert C
This article gives me a clearer idea as to how I want to go about doing this. Thanks for the great tips.

Thank you for taking time out to read the article. We appreciate it. Thanks. -Albert Cantu
I really appreciated your tip on doing regular maintenance on your AC unit. I didn’t know that running an AC at 20 degrees less than the outside temperature could put extra stress on it. It sounds like these tips could help save a lot of money, however if things ever do break down with my HVAC unit I think spending a few bucks to call a professional is worth the comfort.
Thank you for taking the time to read our blog post. We appreciate your feedback. We’ll continue to put out more blogs that will be helpful for customers like you.
Thanks for sharing all of this advice on keeping your air conditioning running smoothly by maintaining it. I had no idea that the system could be running for more than 12 hours every single day— that’s a lot of working time! If that’s the case, I can definitely see how the US is spending up to $11 billion annually.
As an HVAC Engineer Colorado Springs
I confirm that spraying the condenser coil will improve the ability/efficiency of your AC unit.
It is, however, important to remember that the coil can be sensitive to high pressure water, which could cause deformation. I recommend feeling the metal softly so you get an idea for how firm it is, and keeping the water low to start and increase slowly. Finally, you should also spray THROUGH the coil, not at the sides.
Letting your Air conditioning unit have plants grow all over the side of it will cause you a lot of problems. You are going to be spending a good chunk of cash on repairs for it in no time. Keep plants clear of your AC, this way it doesn’t break down, and you don’t have to pay to fix it as often.
Cleaning the unit is such a great idea. During the fall, a lot of leaves and dead branches can get stuck and crowd your air conditioning unit outside so it is a good idea to check it every now and then. We need to give ours a tune up before the hot months really set in, thanks for these great tips!
Albert, do you know the best way to clean our air ducts? I recently moved into an apartment and I don’t think that the air is flowing very well. Everything seems to be functioning properly but I can’t really feel the cold air unless I’m standing right by the vent. I will have to look into talking with a professional like you suggest. Thanks!
You’ve provided some great tips as well as covered some important issues/topics. Replacing the filter regularly being the most important.
I have heard the debate over pleated filters though. As you know the percentage of people who forget to replace their filter regularly is very high. Causing air flow restrictions, not to mention the pleated filters are already more restrictive by design. Thus causing the blower motor to run at higher amps, higher run temps and shortening the lifespan of motor.
I’d much rather let some dust bypass the cheap/less restrictive filter and clean the coil/blower housing as needed. This would include the cost of maintenance yearly but is actually required by the manufactures these days to maintain their warranties(not upheld usually though). Plus this regular maintenance would increase efficiency and lower energy usage/save money.
Of course if the filters don’t get replaced but once a year or when the coil freezes up neither option matters.
What’s your thoughts on the restrictive filter debate?
Thanks for the post! I thought it was interesting that 60% of your energy bill can be spent just on keeping the HVAC system running. When the heat rises about 20 degrees above your set temperature the system works even harder to keep up with the demand for air conditioning. My home has a swamp cooler instead of a full A/C and I end up having it run nonstop during the summer when it is just too hot to do anything. I really appreciate the advice you have given in this article, I will need to get my system on a more regular maintenance schedule.
Thanks so much for the list of common problems with an air conditioning unit. My husband is in the process of finding someone to come in and repair our broken air conditioner. I appreciate this list so that when our AC unit is fixed we can keep it properly maintained.
My AC unit broke down this past week and I’m trying to find someone to fix it. In the meantime, I’m also trying to find ways to keep my unit running smoothly after its fixed. Thanks for the list of common problems with AC units.
My husband told me that our A.C. hasn’t been working properly lately, and I was pretty worried. I looked up some common issues, and now I’m thinking that it was the filter. I think I may just hire a professional to come and look at our A.C. Wouldn’t want to break anything anymore that it is broken.
Since summer is in full swing, I have started to worry about my Air conditioner. I had no idea that if your thermostat is set 20 degrees below what the outside temperature is then it will run more. I always thought that you were safe if it was 20 degrees lower. I will have to remember that.
Hi Gregory. Thanks for your comment. Glad to see our tips are helpful. Enjoy your summer.
I’m so grateful for Willis Haviland Carrier for creating the AC unit. Without my AC unit, it would be so hard to enjoy my home and be comfortable while being home. I’ve been wanting to learn more about regular maintenance like you mentioned, so I’m hoping to find a good professional that I can call if things go bad with my AC unit.

During the last month, I have replaced my 12-year-old, 4-ton, 10-SEER unit with a 17-SEER, two-stage complete system for $10,000. The dual stages mean that the system should run as a 2-ton unit unless it is under severe load. Yet with all other factors being the same, my monthly energy usage has been close to the same amount as last year (approximately 60 kwHr per day). Although this summer is hotter than last year, I still would expect a significant drop in my energy usage, say, 40 percent. Am I being unreasonable to expect a significant return on my investment? At my request, the installer has recently checked and confirmed that everything on the system is functioning as it should. My indoor temperature is set at 76 degrees, the same as last year.
Hi James, We apologize for the late response. Our blog system has been down for a while. Although your new system is a lot more energy efficient, how is your insulation? How much air infiltration do you have? Is the home leaky? Are the windows in good condition, do they leak? All these factors could play a roll in how your HVAC system operates. Based on our rate of 10.4 cents per Kilowatt Hr, the 10 SEER is about $1,117 a year and the new 17 SEER is about $657 a year that’s a $460 difference. Divide that by 12 and its about $38 less a month, which is a 41% savings. So I don’t think your being too unreasonable about the lack of savings. There may be other factors involved. Now we do recommend keeping the thermostat set 78-80 degrees for optimal cooling and for efficiency and use ceiling fans in rooms that are occupied. Try turning it up 3-4 degrees when you leave the home for extra savings. And you may want to consider a home energy audit to see if there are any other areas in need of improvements.
Thanks for writing in James.
I did not know that people have been battling the heat with air conditioning since 1926. I find that this is a great invention that allows us to accomplish lots of things in life. Thanks for the tip about the importance of regular maintenance. Something to consider would be finding a professional to do repairs for a reasonable price.
I have been having some problems with my air conditioning this summer, so this is definitely a help. I have not really done regular HVAC maintenance though. How often do you think that it is necessary to have my AC unit inspected?
Thanks for chiming in. It’s recommended that your HVAC system be serviced twice a year. Once in the spring and once in the fall. Your goal is to make sure it’s working efficiently and won’t breakdown on you during extreme hot and cold temperatures. September 22 is the first day of fall so that’s a good time to schedule a tune-up. Have a great weekend. -Albert Cantu

Thank you for these great tips. I will try implementing these tips. I guess it will increase the overall efficiency of the unit as well.
Awesome, thank you for sharing post.
I didn’t realize that you need to clean off an outside air conditioning unit. That does seem like a good thing to be aware of. I just bought my first home and I want to make sure that my AC is going to work properly.
Always check filters. Cleaning the air filter is important for two major reasons. First, dirt and debris that build up on the filter prevents air flow and ultimately makes your A/C run harder than it has to, driving up utility bills and lowering the life span. Second, a dirty filter eventually allows dust and dander to creep through, which in turn is delivered throughout your home creating impure breathing conditions. BTW, nice tips.
my tip would be do not live in AZ like I do! My AC breaks down so often
Awesome, thank you for sharing post. keep it up.
It was nice to be informed that the air ducts might be clogged or constricted if the airflow is low, so it is best to call a technician to work on it. It might not be considered an emergency for some, but my son is very sensitive to the heat, so I cannot afford to let the airflow stay low. I will be sure to hire an AC technician to check what is wrong with the system as soon as I can. Thanks!
I never knew that if the temperature outside is more than 20 degrees higher than your thermostat setting, your air conditioning system will run even more. I need to get my AC looked at before I turn it on again in the spring. Thank you for the tips on preventing problems with your AC.
I like the fact you shared about Willis Haviland Carrier and how he invented modern air conditioning for homes. I would say that installing an A/C unit in a home is the most efficient way to keep cool at a reasonable price. If I were to need a new air conditioner, I would purchase a Carrier unit from a reliable supplier in my area.
Great Post!Thank you so much for sharing this kind of wonderful things.
The wonderful article you have posted. Very informative.
It’s cool that your HVAC system accounts for roughly 60 percent of the cost of your energy bill. My brother and his family recently moved to the desert, and they want to make sure that their home is cool during the summer months. I’ll share this with them so that they know how much their AC is responsible for with their bill and so that they can be sure to have a professional repair their system and keep it running efficiently.
Thank you for your tip to check the unit’s drain to make sure it isn’t clogged. My husband noticed some issues with the air conditioning blowing out cool air. I will check the drain but if that doesn’t work I’ll have to call a professional in.
