"Had my spring maintenance done and couldn’t be happier with the service. The technician was on time, professional, and took the time to explain everything clearly they also swapped out my nest thermostat for an ecobee and got it set up. Everything is running great and I highly recommend Pass One Hour."

"FIREPLACE ELECTRICAL INSERT!! We hired Vinc and crew a second time to make the fireplace insert happen. They worked very hard to modify the old brick opening and seal everything up properly. Vinc has great suggestions and ideas! He created us a one of a kind beautiful year round updated look for our home we love & been enjoying for two weeks! We will hire him again!"

I’m Ally, and I started NN a few years ago when I became the sole provider for my two kiddos. I genuinely love what I do for my clients, and hold myself to a very high standard. I pride myself on my attention to details. And love when I get the chance to learn a home, and establish a routine that works for the family living in it. I also enjoy helping those who are moving, I have experience in cleaning Air BNBs and staging them for the next group of folks coming to make memories within them.

Heating and Air Conditioning questions, answered by experts

Yes, but they don’t feel the same as an AC-cooled room. You’ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren’t as capable of quickly cooling large spaces or circulating cold air.

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

During the summer, it’s best to set your AC to 78 degrees when you’re home and awake, according to the Department of Energy (DOE). For better energy efficiency, raise the temperature slightly to 85 degrees while you’re out of the house. The National Sleep Foundation advises lowering your thermostat to between 60 and 67 degrees when you’re asleep.

The cost of R32 refrigerant is about the same as the cost of R410A refrigerant, the most widely available type of refrigerant today. However, R32 systems use about 20% less refrigerant than R410A systems, making the refrigerant less expensive overall.
