Excellent service

Grenz crew arrived exactly on time to install a furnace. They estimated that total installation time would have them leaving the site by 2pm. However, every thing went well and they were finished up by 12:30pm.

This is the HVAC Team you want

This company is fantastic; they go above and beyond to do more than just sell an HVAC system but to make sure you get exactly what you need and are comfortable with the entire experience. Very friendly, professional and knowledgeable. We interviewed multiple companies before selecting Grenz and they were miles ahead of their competition on so many levels. Call them and give them a chance!
