Report
Excellent service from the two technicians who came to my condo to address my heating issue. Turns out the issue was primarily with the thermostat (Nest) but they got it set up properly and working perfectly now. They even connected a c-wire so the Nest can draw power from the source rather than relying on batteries (which drain rapidly). Very friendly and professional service. Creative problem-solvers. Thanks!

I was billed $220 for a 5 minute job. Putting some water in my laundry room floor drain! Included was a Truck charge $50 when the truck was already there for the Condo building issue. When I called to get clarification, the woman on the other end was very rude and did not want to hear my concern. She stated pretty much , it was too bad and take it up somewhere else. The tech did not advise me there was going to be a fee, and really why would there be for 5 minutes! I would never recommend this service to anyone. Its truly taking advantage of someone. Well not me! It could have been different

I will never call you for your services since Saturday when one of your drivers in your clearly marked van tailgated me for several kilometers. There was hardly any traffic and i was doing the speed limit in the slow lane. What gives???

My mixing valve went out and I've been trying to get it fixed ASAP for obvious reasons. I called Optimum on 9/26 to see when they could get me in and they said it could be as soon as 10/1 and to look out for an estimate & confirmed appointment. On 9/30 I called again looking for the estimate and appointment and the woman on the phone told me to hang tight because they'd get back to me ASAP, but they never did. I wound up using John the Plumber instead and they were very responsive and kind. They came to my home within 2 days and I finally have hot water again!

Had them come in for a repair that ended up being quoted just way too high. Was told my whole unit had to change potentially, even quoted me at 5k for that.
Ended up going with another AC repair technician who quoted the same repair at 700$.
