Frequently Asked Questions
What is the average life expectancy of a gas furnace?
The average life of a furnace is around 15 to 30 years. As long as you have scheduled annual furnace maintenance, it should easily last over 20 years.
How often should I change my furnace filter?
Many factors contribute to how often you change your furnace filters. Generally, you should change your air filter at least every three months. During the winter, when you rely on your heating system more, you want to increase that frequency to once per month.
Why is my furnace blowing cold air?
If you experience a furnace blowing cold air, we can help inspect and service the issue.
Can I convert from electric heating to a gas furnace?
Yes. Converting from electric heat could save you money and energy. We can remove your electric system and install a gas furnace with the necessary ductwork. You can talk to one of our team members to get started on converting to gas.
Do you do emergency furnace repair?
Yes. We are available 24/7. No matter when you call us you will speak to a real person. We have staff on call for emergency furnace repair in London & surrounding areas.
