First Class HVAC has over 40 years of experience in furnace installation, repair, and maintenance. We provide furnace repair services to many Delaware and Maryland residents. Gas, oil or electricity generates heat which the furnace duct system circulates warm air inside the home. A fault in such a system can be hard to find. You may or may not be familiar with the internal workings of your heating system, but our highly skilled HVAC team has the experience needed to troubleshoot any issues you may have with your furnace and get it back up and running in no time. Whatever the issue that needs repairing, our experienced technicians can quickly ascertain what is wrong and get your heating system back on track. There is no need for your family to suffer the cold as long as First Class HVAC is in business!


Most furnace heating systems break down because of a lack of maintenance and not necessarily because of a major fault. To ensure your heating system does not break down right in the middle of the winter season, make sure you have your furnace inspected maintenance before winter sets in. Our technicians will do a thorough inspection of your furnace and fix any issues they may find. Even if your furnace seems to be working just right at the moment, don’t be caught off guard in the dead of winter. Your furnace is also bound to be less efficient as it ages. Regular furnace maintenance carried out by one of our expert technicians will help to extend the life of your furnace so it continues to work at an optimal level.


We install and service all types and brands of furnaces and will have no problem getting your new system installed and running for the first time or getting your old system repaired and back on track again. We offer comprehensive furnace repair services, whether it’s an emergency repair or a maintenance program you wish to setup. Look no further! First Class HVAC is your one-stop shop for all your furnace installation, maintenance and repair service needs in Delaware and Maryland.
