There are several reasons why your ductwork is making a popping sound. The most common reason is when the metal sheet in the ducts expands to accommodate the change in air pressure. While this occurrence is not that detrimental to your system, sometimes, popping sounds from your ductwork also indicate that the duct system is undersized. If this is the case, we recommend that you contact Castle Home Comfort Heating, Cooling & Plumbing so we can analyze your ductwork system for proper design and recommend adjustments.

You may have heard about the phasing out of the R22 refrigerant as mandated by the Clean Air Act of the Environmental Protection Agency (EPA). Unfortunately, you can’t just switch from R22 refrigerants to the recommended chlorine-free R410 refrigerants. The new R410 is recommended only for those replacing or getting a new AC or heat pump. So if you’re worried about your R22 refrigerant on your existing AC or heat pump, the EPA ensures that this refrigerant will still be available until 2020. After that, recycled refrigerants will also be available.

There are several reasons why your air conditioner is freezing up, including:
