❄️🔥 Another Home Ready for Winter!

MJM Heating & Cooling recently installed a steam humidifier to help maintain comfortable indoor humidity levels throughout the colder months.

We also installed two coil access panels to make future cleaning and maintenance easier, along with a UV light system to help reduce microbial growth on the coil and support better indoor air quality.

Another HVAC Upgrade Completed!

Removed the existing air handler and AC system and upgraded the home with a new Goodman heat pump and air handler with electric heat.

We also sealed and rewrapped the existing ductwork, installed a new drain pan with safety switches, and cleaned up the exterior lineset for a cleaner finished look.

Another quality installation completed by MJM Heating & Cooling. The customer was very happy with the upgrade!
