Refrigerant, commonly referred to as freon, is the substance that makes air conditioning possible. The four main components of an air conditioning system, the compressor, the condenser, the expansion valve, and the evaporator, convert refrigerant, circulate it throughout the system, to output cooling air through the vents and into your living spaces.


We offer residential and commercial central air conditioning installation, repair, service, tune ups and maintenance year-round. Maintain your central air conditioning system.


No matter the time of the year, if you have a project that requires AC service, we can help! If your unit has R12 refrigerant (dichlorodifluoromethane, CCl2F2, or CFC-12) contact us today! We are experts in handling R12, a refrigerant that has been phased out.

AIR CONDITIONING

Q & A

  • Do you suspect that your central air conditioning system needs a recharge?

    We are HVAC professionals. We can remove the existing refrigerant, inspect your system for leaks, and complete the ac recharge with new refrigerant.

  • Is your AC unit blowing warm air?

    Your air conditioner may be blowing out warm air because the unit may be leaking refrigerant.

  • Does it look like your air conditioner unit may be leaking?

    If there is noticeable frost buildup around your unit, it can be a sign of leaking. You may see some frostiness around the coils of your unit at times, however, if the unit does not seem to be cooling your home, then there may be an issue that needs to be addressed.

  • Is your AC compressor failing?

    Your air conditioning compressor is perhaps the most important AC component. There are several signs that can potentially indicate an issue with the compressor. Contact us today!
