How many hours should the AC run per day?

• <div><p>On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours. </p></div>

Will low refrigerant cause a coil to freeze?

Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be <a href="https://www.angi.com/articles/does-freon-leak-mean-i-must-get-new-home-ac-unit-cant-i-just-get-leak-fixed.htm">low on refrigerant because of a leak</a>. </p><p>Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels. </p></div>

They were on time for the estimates and the installations. I was told what they would do and they did it. Cleaned up after themselves. This is the second house they installed a new heating/AC unit for me. I've used them twice and will use them again.

"I can not say enough positive about Chris and Chuck and O 2 KOOL!! Chuck came out in early January to look at my old Trane gas furnace .. he got it going with no trouble. Now today ... during our ice/snow armageddon it went out again. I called and Chris FaceTimed with me .. looked at what was up and talked me through how to relight the system myself. Good news .. I now have heat! I strongly recommend them to anyone who needs help with their heating and cooling system! They not only helped, but assured me .. a 60 yr old woman .. everything would be OK and safe. That is a VERY rare quality!"

Family owned business with over 26 years of experience handling all your Heating and Air jobs- HVAC for residential and commercial.

"Pinnacle Heating and Air replaced my heat pump and all ductwork and their workmanship is excellent. Their pricing couldn't be beat. Not only did I receive excellent workmanship and great pricing, Brian and Kelli were always on time, always had the right tools and materials, and right solutions to resolve my unique AC needs. I highly recommend Pinnacle to anyone who wants HVAC work done right the first time. I have had NO ISSUES since the installation and in fact I am extremely satisfied with the whole experience (from the initial quote through quick installation). Kelli even filed my warranty papers for me, a real bonus. Brian certainly knows what he is doing, I have not had this high confidence in any other HVAC companies over the last 35 years of home ownership. An added bonus, having Brian and Kelli in my home was a real joy because they are both cheerful and pleasant to be around. They are extremely fast at returning my calls and texts and you certainly don’t get that with other competitors…recommend reaching out to them!"

Heating and Air Conditioning questions, answered by experts

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

Yes, high-efficiency models reduce environmental impact with lower energy use.

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

Evaporator coils last between 10 and 15 years before they need to be replaced—as long as you stay up-to-date with routine maintenance. This is roughly the same life span as most AC units. So, if you have an older air conditioner and the evaporator coil goes out, it might be more cost-effective to replace the whole unit rather than just the coil.

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak.

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.
