System is 12 to 15+ years old and losing efficiency
Repairs are needed more than once a cooling season
Recent repair estimates are approaching the cost of a new unit
Uneven cooling persists even after past repairs
Energy bills keep climbing as the equipment ages
The system still runs on older R-22 refrigerant
Current unit is undersized or oversized for your home's square footage
A new addition, finished basement, or renovation needs added cooling capacity

3 weeks agoA clogged drain that backed-up that couldn't be solved ourselves required a professional! So glad I contacted ZyNex Plumbing and HVAC! A quoted time slot was provided, and no wait, they were at my home within 30 minutes! Ethan and Jose were friendly, efficient and professional! Definitely recommend!

1 month agoZyNex Plumbing and HVAC did a great job in resolving the plumbing issues at my property. Brian, Ethan, and Blake provided same day service and I wouldn't hesitate to recommend their services.

2 months agoMike, Ethan, Jose, and Bradley were a fantastic group of guys to work with. They made getting rid of a leaking water heater a breeze even though they had little to no room to work in. They also installed a brand new tankless water heater system. They were able to get the job done in a single day! 100% will be calling ZyNex for any future plumbing needs.
