Appointments That Fit Your Schedule

Blue Dot values your time. We know you are busy, which is why we will strive to offer you multiple options for an appointment, whether you need service during the day or after the sun has set. What’s more, we’ll call before the technicians are about to arrive, so you can make better use of your waiting time.

No Extra Charges, Service Available 7 Days/Week

When your air conditioner or furnace breaks down, it’s essential to get it back up and running as soon as possible for the comfort and safety of your family. You can rest assured that Blue Dot will not require you to pay an extra surcharge simply because you need work done after our regular hours. You can depend on Blue Dot to come through for you during an emergency, even if it’s late at night. Emergency HVAC services are no problem!

Before Work Starts, We’ll Give You a Free Estimate

You won’t get caught off-guard with an unexpected bill. Your Comfort Consultant or technician will go through all the details of the pricing for the work they recommend on your system.*This applies only to the installation of new equipment.

Background Checked Professionals

For the peace of mind of our customers, Blue Dot will background check and drug test each Comfort Consultant and technician. We hire only the most talented and knowledgeable technicians, who continue to receive ongoing training. This way, you’ll know our professionals are following HVAC-industry best practices for the work they do in your home.

Your Satisfaction Is Guaranteed

We won’t be satisfied with the work our HVAC maintenance company does until you are happy with the results. So, within the first year after service, if you happen to be disappointed with any of the work we did, we will strive to meet your expectations. Otherwise, we will be happy to remove the equipment when applicable and issue a full refund.

We Offer Outstanding Blue Carpet Service to All Customers

The team at Blue Dot will give you and your home the respect you deserve. Each of our well-mannered, polite service technicians is motivated to get the job done on time and within the budget we established in your estimate. Going the extra mile is second nature to each member of our crew. For example, it’s not uncommon for our technicians to notice a light bulb has burnt out during a furnace repair job, which they can change for you.

I cannot do justice to the overall quality of the service, but I also want to pay homage to the kindness and the generous treatment that I received, in turn, from Adam, Glenn, Justin and Will. It is my pleasure and indeed my responsibility to commend each of them and Blue Dot for having such reputable competent and committed employees.
