Baltimore HVAC Repair, Installation & Maintenance

High-Quality Heating & AC Services in Baltimore, MD

Think back to the last time your HVAC required servicing. Did your previous service provider perform the job and educate you about what was done? Did they ensure you understood how to keep your HVAC running smoothly and provide an honest price on the spot? Our team at One Hour Air Conditioning & Heating® of Baltimore will always make sure you’re a part of the repair, installation, or maintenance process. This is how we build your trust in our heating and AC services and make life easier for you.

Our highly trained technicians provide long-lasting repairs and reliable installations that are 100% guaranteed for 2 years from your service date. This means that if something goes wrong or you’re unsatisfied, we’ll come back to your home at no cost to make sure you’re happy. Just as important, we only hire personnel with high standards of ethics. We ensure each of our technicians is background-checked and drug-tested, so you know your technician is trustworthy.

Not only do we employ the best of the best, but we strive to provide that to our customers as well. Each customer is promised on-time arrival or your service is entirely free! We live by our motto, “Always On Time...Or You Don’t Pay a Dime! ®” and it conveys how serious we are about providing best-in-class AC repair, installation, and maintenance services every time.
