Thank you to Ivan and his team for the great job in the total refurbishing/ replacement of our 25 year old oil heating and air conditioning system at our cottage in Mount Gretna. From identifying the need during the annual check up through the quoting, ordering process and installation, everything was done very professionally and expediently. These old Mount Gretna cottages can be a real challenge, but, they worked through it and everything is functioning perfectly.

I've been a client of Modern Comfort for nearly 20 years... I've never been disappointed with their service. Just had another great service call by 'Scotty' who was able to resolve my problem with minimal fuss. Great service, Scotty!

The techs that work for MOC are SUPER GREAT! All are very knowledgeable, professional and really care that I understand how my system works and, if needed, why a repair is required. In addition, the customer service reps are very friendly and helpful when I call to make/change an an appointment. The phone is answered quickly and the technician arrives on a timely basis. I've been with the company for more years than I can remember.
