"This was a disaster that left me so angry I was literally Shaking! This company was sent by HSA Home Warranty another disaster look them up before you sign up. Anyway Simco was supposed to inspect the hot water heater for a leak to be replaced under the home warranty. The guy right off made a backhanded threat that he wouldn't condemn us and then became accusatory about the insulation on the water pipes saying what are you hiding here...the insulation was on the hot water side and was there when we bought the home this past November then he started nosing around and making other ******** comments. I worked in the trades myself and got very alarmed as he constantly was looking at gas pipes etc. This home had an engineer performed and certified inspection last November. I cant imagine what would have happened with an elderly and or female client. When I started questioning him he became very defensive and when I left to get my phone to record him in action he decided to leave!! Thank god for that!!! This is the worst experience of my 60 years."

Heating and Air Conditioning questions, answered by experts

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

While personal preferences widely vary, sleep experts say the best temperature for sleeping is between 60 and 67 degrees Fahrenheit rather than 78. If you do choose to sleep with your AC unit tuned to 78 degrees, you might want to use only a sheet or light blanket rather than a comforter. You might also consider installing a window unit in your bedroom so that you can be cooler in bed without wasting energy cooling the whole house.

While it is possible to add Freon to your AC unit yourself, it is not recommended. In fact, the U.S. Environmental Protection Agency (EPA) prohibits the handling of Freon without a license. Freon is a dangerous gas that can cause irreversible damage to your AC or yourself if not installed correctly. It is worthwhile to hire a professional to add Freon to your AC.

Modern AC leak sealants work as a temporary measure to stop refrigerant leaks. You can purchase them at most home improvement stores or on online. When using an AC leak sealant, keep in mind that it’s only a temporary solution, so you’ll still need to hire a pro to install a replacement part as soon as possible.
