In 2017 I purchased an AC and heating system from DD Mech. I had about 3 issues with the AC unit not functioning properly during the summer. They came and addressed the issues but 3 months ago, I was told that the 10 year warranty provider was bankrupt. Therefore if I need parts and service, I'll be charged because I have no coverage. I was also told that they are seeking a new warranty provider and that they will inform me when they found one. There are no legimite excuses for this. I am still waiting for a new warranty provider. BEWARE of this company!

The heater quit working and started blowing just cool air I had 3 quotes to see what was going on get this. 1st quote (not disclosing company) said the company who makes our furnace and ac unit went out of business in 09 and parts for it will be nearly impossible to come by and that we should replace the entire unit and furnace as well as there is so much rust build up and if a hole pops through the rust it will leak carbon monoxide. Quoting $8000 for whole replacement and labor. 2nd quote (not disclosing company) said older stuff works better your ac unit is in great shape.

For your furnace we would just have to search really hard for some parts to fix it quoting $1500 3rd quote DD mechanical services said your furnace wasn't getting the correct voltage on the ignition module, one of the switches is open, they replaced the switch and our Heater is now working for less than $300 Not sure how all 3 companies had something different to say but what matters is I will continue to use DD mechanical services. They did not try to get a whole bunch of money out of us, they came and fixed it with no problems. Moral of the story always get multiple quotes, dont go with your first choice.
