Air Conditioner Blowing Hot Air – Hello Richard, my air conditioner is blowing hot air today and I am wondering what’s going on with it. It is mild weather here and still winter, but the temperature here got above 80° F today, and when I came home from work, I decided to turn the AC on to cool the place down a bit.
Cooler weather hits tonight when it’s going to be around 40° F according to the forecast. Is this something I need to worry about right now?

What do you do when the Air Conditioner Breaker Trips and it won’t reset? What to do if the breaker keeps tripping? Try to reset it. If that doesn’t work? What do you do when it trips again?

Sometimes the problem with the air conditioner breaker trips is simple. However, other times, they are complex and result in significant repair.
Here we’ll describe the two separate line voltage circuits for your split system air conditioner. Additionally, we will also describe the possible causes that will make your air conditioner trip the breaker. If you have a package unit, then you will have a single circuit for your air conditioner. Lastly, a package unit is an air conditioner or heat pump in one package (all in one air conditioner).

Hello, We need to ask you about water damage and how an air conditioner can cause this kind of damage. The whole ceiling in one of the rental properties just fell into the living room. All the drywall and insulation from the attic fell and caused damage to our tenant’s furniture. Thank God the tenants were not at home and injured when the ceiling fell in.
HVAC Tip - According to studies done by the Department of Energy, 50 percent of the heat loss experienced in the average home occurs through the ceiling. That makes a lot of sense since heat rises. You can reduce that heat loss (heat gain in the summer months) by adding another layer of insulation in the attic. That will hold more heat in our homes for a longer period of time which means the furnace will cycle less. That means you are going to save money. A lot more money than another layer of insulation costs. Additionally, having an attic fan controlled by a thermostat installed in your attic will remove a lot of heat in the summer. This will help you, in addition to having more insulation, reduce heat gain from the attic in the summer.
