Extremely disappointed with my experience with Blue Dot. From the very beginning, the technician arrived late?even outside the scheduled appointment window. When they finally showed up, they misdiagnosed the issue with my AC unit, which led to further delays and frustration. To make matters worse, there was zero communication after the visit. I was left in the dark with no updates or follow-up on next steps, and the issue remains unresolved. For a company that claims to offer professional HVAC service, this experience was anything but that. I expected better accountability, accuracy, and basic customer service. I won?t be using them again and do not recommend them to others.

Central A/C Installation
I called a few HVAC companies on a Saturday morning, due to my A/C only blowing cool to warm air. After speaking with a couple of other companies that advertised as providing 24/7 service, Blue Dot was the only company that would come out on that Saturday. The technician that came out was named Dwight ("DJ"). DJ was exceptional! He took the time to explain what he was doing and why it was necessary. He also provided tips on how to maintain the a/c unit to keep it running efficiently. He was courteous, professional, and patient with answering my questions with a positive attitude. He repaired the unit during the visit. DJ turned a stressful situation (worrying about the possible repair) into a smooth and reassuring experience with his expertise and positive attitude.

The tech Blue Dot sent is a pro who’s been here before and did the quality semi-annual maintenance I expected on my HVAC system.

They accepted a job and refused to start work because of a "safety issue" they "didn't find" until after we'd signed a contract and I paid them $7500. It's been two weeks and they were happy to keep my money while they made me fix it at my own time and expense. Several professionals have since been by to look at the issue and all have confirmed there was never any danger. I have no choice but to continue to work with blue dot, but if you're not in that situation I beg you to look elsewhere.

Both technicians were outstanding. Mark Green did the annual tune-up and took the time to explain the details. I replaced a condensate pump later that day and accidentally tripped the secret circuit breaker located behind the bolted panel which is behind the outside panel. Paul was the 2nd technician who knew exactly what was wrong and reset the breaker and the flow of cool air again was magnificent.

Heat Pump Installation and Replacement
$12,000
Salesman promised top tier, best trained installation technicians. I got the worst installation experience I could imagine. A 1 day promised install of water heater and heat pump took two full days over 4 elapsed week days (7 days if include weekend). At the end of both days here, they left trash, old system parts, unused hardware, sawdust & brick-dust from cutting plus left some tools behind. I would visit them periodically and ask how it was going, technicians NEVER gave any feedback or asked my preference on any option of positioning items, location of new outlets - or even an alert that new holes in walls and new outlets and circuit boxes and wire runs would be installed in new locations - even through exterior walls! Weren?t truthful about when would return to finish. Charged for thermostat didn?t install. Left without even walking us through the new equipment or any explanation of how to use it. Sloppy, unprofessional work manner leaving site dirty, not picked up.

The tech pro was very efficient and knowledgeable. He did the Inspection and maintenance required and informed me of optional improvements that can be added to the AC system.

The tech, Cory, came for a semiannual maintenance check when he diagnosed a problem. Parts were ordered, arrived and Cory returned to complete the repair. Each time, he was knowledgeable, as expected. What made him exceptional was his kindness, patience and communications about the repair and what to expect during the lengthy repair. Upon leaving, he clearly explained what to look for to insure proper workings. I hope Cory is my rep in the future.
