Sounds like you have an internal heater box issue. Possibly one on the mode door motors quit or you have a broken door inside heater box. To access heater box, you have to remove entire dashboard assembly. This is not too simple of a task.

It is likely you have a heat pump. A type of air conditioning system which heats as well as cools. If there is cold air coming from the outdoor fan, you are in the heating mode.

The Rewards of Heating Jobs?

There are many jobs that offer a sense of accomplishment along with the gratitude of the company's clients. One job that offers satisfaction and pride is a heating job. When you start working in the heating and cooling industry, you take on several layers of responsibility. You have a responsibility to the company to maintain your technical skill set and customer service skills, you have a responsibility to the product manufacturers to properly represent the products and your customers rely on you to provide important heating and cooling services.CertificationsWhen you see a commercial for a heating and cooling company that mentions certified technicians, that is a very important statement. Heating jobs require constant training on the products themselves, how to install the products, product maintenance, troubleshooting and product safety.There is a tremendous feeling of pride knowing that you are able to maintain your heating certifications while also performing your regular job duties. As the technology in the heating and cooling industry changes, it is your job to keep up with it. The more you learn, the better you become at your job and the more satisfaction you get. Customer SatisfactionIn many cases, customers call a heating company in a emergency. Having a certified heating technician come out on a weekend, holiday or late at night often costs the consumer a premium on top of the regular price. When you arrive, the customer is feeling helpless and frustrated.Your job as a heating technician is to make the customer feel at ease, solve the problem and then explain how the billing works. The customer expects you to be honest, knowledgeable and understanding. If you can bring those skills together and develop a good customer service rapport with clients then you will enjoy a long and successful career in the heating business.People either bring in a heating company to give an estimate on a new build or they call in an emergency to have the furnace repaired in the dead of winter. As a heating employee, you are expected to give good advice and solve the problem. It can be one of the more rewarding careers you could ever have.
