To those looking for a professional and trusted HVAC installer, look no further.
My furnace exhaust fan failed during winter of this year and after searching my local area, I found Mount Joy Heating & Cooling. They were able to identify the problem and fix the issue the next day. During the visit, they offered us their portable electric heater and made sure our gas fireplace that we rarely use was being vented properly and passed their carbon monoxide tester. I also learned the owner was a genuine HVAC professional for both residential and commercial properties.
After that great experience, I did not hesitate to ask them to install a Vanee HRV and Rinnai tankless water heater. They sent proper quotes and receipt for each unit. It was installed according to code within the day and the system is working great.
I highly recommend Mount Joy Heating & Cooling.
