Heating and Furnace Services

Blue Dot of Maryland keeps you comfortable in the winter, in more ways than one. Whether you need heating repair, maintenance or new installation, Blue Dot is ready to provide you with exceptional service.  And as always, estimates are always complimentary for your new heating and cooling system installation! Your calls are answered by an empathetic, knowledgeable human on the other end, rather than an answering service. We provide 24/7 Emergency Service, with staff members on call during and after business hours to better serve your heating & furnace repair needs in Baltimore, Forest Hill, MD and surrounding areas.

You can also call 410-809-2124 for immediate and emergency service!


  • Heating Repair: Need heating repair in Baltimore, Columbia, Annapolis, or Bel Air, MD? Blue Dot of Maryland is proficient in providing superior heating repair service. Schedule a heating service call today. For emergencies, call us at 410-809-2124.
  • Heating Installation: When you need a heating system, we sell and install heating and furnace systems from leading manufacturers. We stand behind our work with great parts and labor warranties.
  •  Maintenance: A properly maintained air conditioning system can actually lower your heating bills by as much as 35%. Get our AC System Check to make sure your unit is performing as efficiently as it can be, or consider a Preventive Maintenance Plan to keep you covered all year long.

You will appreciate the fact that our technicians and service team are polite and will go above and beyond the call of duty. For example, if a customer also needs a light bulb changed, our Blue Dot service team has been known to do that.

Blue Dot provides all of our customers with quality services, such as our seasonal 24-point furnace, heat pump, or air conditioner inspection. We pride ourselves on responsiveness and close attention to each customer’s needs. When the temperature drops, our concern for you rises. We deliver industry-leading systems and services, with Professional Comfort Consultants, to prevent you from getting caught in the cold.

Everything with Blue Dot has been great. The installation today was quicker than they estimated and our install technicians were friendly and helpful. I will definitely use Blue Dot for future services. They were great!
