Hi, I had a ventilation system installed and was a good experience. Was a hard work as no one new I have unusual thick concrete walls, so was much more difficult work that they expected, and an additional specialist to cut the concrete. They did a great job, tidy up the place and the system works very well. I choose them as a friend of mine recommended them. They was by far more affordable than any other quotes I had and their system work with air extraction from inside roof cavity or outside air, which was and is a good feature, as most other companies are offering only roof air cavity which is also dusty and not always best option. From what I read on the government website guidelines. Very happy and thank you very much for all your hard work and extra effort to get the job done properly


We had a positive pressure ventilation system installed by MJ’s team from Pacific heating and cooling at our previous, 60 year old house a few years ago. The result was excellent, the morning condensation on the windows disappeared immediately, and the house felt dry and fresh. We then built a new house, where we had them install a balanced-pressure ventilation system, and heat pumps. Very happy with the results there also. For both projects we were able to have honest discussions with MJ to work out the best system for the house. His team then installed the systems quickly and professionally. And their ventilation systems are much, much cheaper than the big name brand like HRV and DVS.

Being long term customer of Pacific Heating and Cooling, I’ll say they have qualified professional staff and always do their job in timely manner. Communicate easily and clearly. They have installed different type of heating and cooling system for my parents and my house. We’re 100% happy with them.
