Bob and Tim have arrived at a customer’s house that uses fuel oil for heat. This is a “no heat” call — the customer called first thing this morning and said that the oil furnace was not coming on, and the house was cold. When they arrived, they talked to the customer, and the customer said that he had made several tries to get the furnace to operate but with no luck.

Bob and Tim were at a customer’s house doing a seasonal checkup on a condensing gas furnace. This was routine service carried out every year on this customer’s equipment per a service agreement. But when they tried to operate the furnace, the burner would not light.

It was the first really cold day of the winter and Bob and Tim were on the way to a service call on an oil burner. The customer said that they had no heat. It was about 15°F outside so they were in a rush to get there.

Frozen condensate occurs when condensation and exhaust gases generated from the heating process are discharged outside via a vent pipe and freeze in the cold air. If ice continues to build up, the vent pipe can become blocked, causing the furnace to shut down. 

Bob and Tim were on their first service call of the winter season. A customer wanted them to perform service on their furnace to make sure that the unit was in good working order for the winter. 

Bob and Tim were on their way to a no heat call for a gas furnace. Tim asked, “What do you think we need to look out for on this call?” Bob said, “It could be any number of things. We will start by talking to the homeowner and see what she knows.”

Bob and Tim were doing a routine seasonal service call on a high-efficiency furnace. Tim asked, “Why were the older furnaces so inefficient compared to the more modern furnaces?”

There is no question there are some chilly months ahead, and homeowners will expect their expensive condensing furnaces to operate without fail, even on the coldest days. 

Bob and Tim were on their way to do routine annual service on a customer’s gas furnace and humidifier. Tim asked, “What are the things that we should look for that may cause problems on a gas furnace?”
