"They are excellent. I am a truck driver and not home very much. I needed my pipes winterized so they wouldn't freeze. The antifreeze is non-toxic. They drained my hot water heaters, put the antifreeze in. He turned off the water and made sure that it was winterized. I could turn the heat off. I thought it was high until, I realized they used two cases of antifreeze, and it is expensive. They were professional, courteous, and no issues. The price was good. I have no complaints with anything they did. I had to make an appointment, because they are busy. It took a while for them to come out on time and they showed up on time. Everything was good. They provided a good quality service at a reasonable price."

Heating and Air Conditioning questions, answered by experts

Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a local air duct cleaner to clean and inspect them.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

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.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

It depends on the size of the space you’re cooling down. If you’re looking for the most affordable way to cool an entire house over a long period of time, then central air will be more cost-effective. But when it comes to cooling down a couple of rooms or one floor, a window unit may be the cheaper option, with both a lower cost to install and less energy used to run.
