I got a next-day appointment for my broken AC unit, and the service tech arrived on time, completed the work in just a few hours, and charged what I consider a reasonable price. Would definitely recommend and use them again.

The pro was awesome. He troubleshooting did an eval of the entire system and the wiring and quickly found the issue called it to confirm the warranty and quickly took my service fee payment without hassle. He was professional, courteous, and very knowledgeable. The blue dot service technician was great.

Heat Pump Repair or Service
Anthony Aye was my service technician today. He was very polite and professional. He ensured he wore foot covers to protect the floors. He did an annual tuneup on my HVAC system and took his time and noted and thoroughly explained any potential issues to me. He gave me other available service/installation options to look into for the near future. Overall, he was very pleasant and respectful. I would recommend Anthony Aye to anyone who is looking for a true professional and is very knowledgeable about different systems.

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.

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.
