Furnace Diagnostic

The first step in any furnace repair is determining what the problem is. Our qualified technicians will run a full diagnostic on your furnace, including safety check, in order to properly assess the situation. If your furnace is experiencing a problem that can be resolved quickly, we will identify and fix the problem without delay.

Furnace Maintenance

You can prevent your furnace repairs and ensure efficiency by getting seasonal maintenance & cleaning your furnace every year. It's best to schedule maintenance prior to the heating season. You might also hook up a carbon monoxide alarm in your house and change out the furnace filter routinely. When dirt is clogging your air filter, your furnace has to work harder to circulate air. Failure to clean out your filter will result in dust settling around your home. You'll also want to keep combustibles (paint thinners, gasoline, etc.) away from your furnace to douse any possibility of a fire starting. Improper maintenance is one of the main reasons we get called out for repair.

Customer Reviews


Just had the annual heating system tune-up carried out by Sergio Ruano from Stewart Heating and Air. Sergio provided the professional, high quality service that the company prides themselves for. Sergio arrived in plenty of time for the scheduled appointment and got straight to the task at hand. Sergio took time out to answer any questions I had as well as explaining some of the inner-workings of the heater system... tips on things to look out for, etc. I highly recommend Sergio as well as Stewart Heating & Air.
