Simple project to install a bidet attachment on an existing toilet. I will find out more about it once my fiance arrives at the end of September.

We met with a few HVAC installers and Supreme Air quoted the lowest prices and gave us 3 options to choose from. No games, no pressure tactics, and no unexpected charges. They were very prompt, professional, and did a great job.

Horrible. Paid for annual maintenance contract on four units. Called when one unit wasn’t working and never heard back from them. After many attempts finally talked to office worker and scheduled appointment. I called the morning of the scheduled service to confirm timeframe and was assured they would show. When it was time for them to arrive received a call they had to reschedule. Very rude office support that could care less. Asked several times for the owner to contact me and still has not. Do yourself a favor and find another company.

I also needed a chimney and they coordinated with the chimney company which made this easier for us.

Paul was our plumber - very nice, professional and great conversationalist. He diagnosed the source of our stoppage, and was correct. Did the service in an hour, clearly told us the cost upfront, and then did the work to our -- and his -- satisfaction. Called when he left the shop, arrived exactly when he predicted, and got right to it. Very satisfied to have Supreme out again - I could not remember when they were here before, which Paul said was a good sign. Great service.

Supreme was polite, professional, and timely. They serviced the system and explained what items require repairs for long-term efficiency. I was very pleased and contacted them again for another system's servicing.
