Frequently Asked Questions

How long does a furnace typically last?

This varies depending on the type of heating installation and maintenance frequency. Gas furnaces usually last between 15 and 20 years, while electric furnaces can last 20 to 30 years.

Why is my furnace blowing cold air?

Reasons for this can include a clogged air filter, thermostat setting issues, or ignition failure. It may or may not require a professional furnace repair.

Can you help me decide between a furnace and a heat pump?

Yes. If electrification, rebates, comfort, or cooling are part of the conversation, we can compare furnace replacement with heat pump options instead of forcing one answer.

Should I shut the furnace off if I smell gas or burning?

If you smell gas, leave the home and call the gas utility or emergency services first. If there is an electrical or burning smell, shut the system off and call for service.

How long does furnace installation take?

Many straight furnace replacements can be completed in a day, but duct changes, access problems, venting corrections, or electrical and control updates can add time.

Will you check the ductwork too?

Yes. Duct problems can make a new furnace feel like an old one. Airflow and return air are part of a responsible heating replacement conversation.

Why isn’t my furnace producing enough heat?

Dirty or clogged air filters are the most common reasons for furnaces not producing enough heat. There also could be blocked vents preventing heat from adequately distributing through your home.

Why does my furnace keep shutting off?

The furnace might be shutting off and turning on, or short-cycling, because of a safety sensor shutting the system down. it is a good idea to have a professional inspect this issue.

Why is my furnace making unusual noises?

There could be loose parts, an electrical issue, restricted air flow, or a blower motor problem depending on the noise and most likely requires a heater repair service.
