Alex is super friendly, and was super helpful in assessing why our boiler stopped working. It was the coldest day of the year and he made sure we were not left without heat. Very knowledgable and careful to repair what was at the root cause. I will hire him again and recommend him to those looking for an honest pro. He also does appliance repairs, and he’ll be my first call when something goes wrong.

Alex did a good brazing job in my condo. I loved that Alex collects good information before the start of the work and gives you a cost estimate, which is very rare among other HVAC and plumbing professionals I have seen. Pricing is very reasonable. He is very responsive and on-time.

Had a condenser break, Alex was very quick and professional with getting my cold air back and running. Fair prices too, he’s the only guy I’ll ever call for my hvac needs.

Cepheus are amazing, they did ductwork and AC installation for me. Alex and Andrew are a pleasure to hire They are very knowledgeable and capable, as well as being friendly and easy to work with. I couldn't be happier. I will use them in the future. To be honest, they can fix and install almost any system, and give good quotes, so just ask. Thanks guys!

The guys did an awesome job - extremely efficient and honestly quite flexible for the schedule we were on. Had to get the team to revisit us when we ran into a difficulty on our side and they were able to accommodate well. Our premises had multiple access points and they required a bunch of residential and commercial acces. They acted extremely professionally with everyone involved. Will be using again
