frequantly asked questions

What Makes A Furnace Malfunction?

There’s no one answer, but there are a few areas to quickly check. For example, head to your circuit breaker box and see if it accidentally tripped. Next, check your air filter. A dirty air filter can cause problems for you. Lastly, see if the battery in your thermostat is working, and make sure it’s properly turned on.

Before I Call You, Are There Things I Can Do If My Furnace Isn’t Working?

Step 1. One thing to check is your thermostat. Make sure it’s set to “heat” and turned on.

Step 2. You’ll also want to check the furnace switch. Is it set to the “on” position?

Step 3. Check the circuit breaker. Has the furnace one been tripped?

Step 4. Have you checked that the furnace filter isn’t clogged? It might be time for a new filter.

Step 5. Is the front panel of the furnace securely closed?

Step 6. Check the gas valve. Be sure it’s set to the “on” position.

Step 7. Check to see if the air ducts are blocked.

Step 8. Is your unit still not working? It’s time to call a professional.

How Many Years Does A Furnace Last?

Depending on the type of unit you have, and the way you take care of it will alter the lifespan of your furnace. In general, an oil furnace will see about 15-25 years of life while a gas furnace gets about 15-20 years of use.

How Do You Decided When It’s Time To Replace Your Unit?

The age of your system is an important factor. You should also consider the cost of the ongoing repairs, along with the frequency of repairs. Using the $5000 rule, what we do is multiply the age by the cost of repair per year and if that is less than $5000, we recommend that you repair the unit. For example, if your furnace is 12 years old, and the repair will cost $500, multiply 12X500=6000, which is greater than 5000. In this scenario, it’s better to replace than repair.

How Much Is An Average Furnace Repair Bill?

An average bill depends on many factors. You need to consider things like labor, parts, if it’s under warranty, and what type of unit it is. That being said, an average repair bill runs right around $300. We find $170 to $500 is the range we notice the most but be aware a repair bill can run anywhere from $100 to $1200 depending on the situation.

When Should I Do My Furnace Maintenance?

Yearly, right before it’s cold. We recommend you do this to both extend the life of your furnace and to help it run more efficiently. Also, your manufacturer’s warranty may require a yearly inspection and maintenance for them to pay for any issues that arise later.
