Surprised but satisfied

Dor Mar sent someone out to us the next day after my request the prior evening. Although we didn’t expect to need new equipment which far exceed our budget, our tech, David explained everything in an easy to understand manor which made the decision to upgrade more palatable. I especially liked his knowledge of the AC system and his determination to offer discounts for the new system. I would certainly like to use him in the future for maintenance of the new system.

Can improve customer service better

Aaron Curry performed replacement of Limit switch and ran the HVAC and checked for any abnormalities. He also performed a preventative check on AC. He gave a clean chit to HVAC and AC. Appreciate his thoroughness. Dor-Mar Operations and Sales team could be more customer oriented and try to understand issues from customer perspective. They also need to revisit their policy of charging the customer, a labour charge every time they visit a unit even if it is a resolution of one single incident through two visits (one for diagnosis and one for replacement of a faulty item.)

Excellent service

Aaron Curry came for troubleshooting HVAC and did a detail check up and possible diagnosis. Though we still have not identified potential issue he was willing to give it a trial and narrow down the defect. He was also able to explain it to the customer where the issue could be. Appreciate his detail.

Reasonable pricing and quick service.

DOR MAR replaced a motherboard for my HVAC recently as part troubleshooting for HVAC failure. They were reasonably quick in getting the motherboard changed. I am happy with the service and reasonable pricing.

Excellent Service - HIGHLY RECOMMEND!

They came out same day at no extra charge and David was very informative and took the time to explain what was wrong. Even took the time to double check everything before informing me I needed a new thermostat.

Excellent customer service

Doug and Ryan are extremely professional and courteous. After our installation, they both made sure we did not have any questions and informed us how our new unit will perform, including the thermostat. I highly recommend Dor Mar.

Very thorough inspection, many improvements made

Brad was very detailed in going after and repairing leakages in the heating duct system. I feel he went above and beyond what was required. He gave many helpful suggestions as well relating to overall maintenance and safety. 10/10 great job.

This is a tankless tank system. Has a Rinnai tankless attached to the 40 gallon water heater. Bring vinegar for this flush, and flush sediment out of tank. Radon below 2 picocuries. Sump pump is new. Tank flushed great, tankless did as well. No failing parts, water pressure is between 40-80. Leaks on plumbing lines and dialectic nipple. Customer reports water comes out of the shower head orange. Would like lead plumbers oversight or a follow up with the customer.
