Report
We got a quote at the end of 2019 for an entire heating system, forced air furnace, A/C, and all ductwork in a 1960's bungalow to replace the electric heating. Due to Covid we had to delay the project, the system was installed in April 2021.
Brian honoured the origanl price quoted and only asked us to pay the cost increase of some of the materials (that only added a couple hundred dollars to the price). The crew was very respectful and professional and the quality of the work is outstanding. I highly recommend Paterson-Lange Heating and Air.

Another company was going to charge us $1500.00 to repair our air conditioner and after waiting for two weeks in extreme heat they still hadn't shown up to do the work. We called Patterson Lange in the morning and they came out a few hours later and repaired it for only $300.00. Appreciate the honesty, quality of work and blazing fast response from these guys.

Deplorable! This business is around the corner from me and they could not be bothered accepting the work I was offering them because it was small potatoes.
