How Often Should Furnaces Be Cleaned in Sudbury?

As a general rule, property owners should have their heating system properly maintained at least once per year by a certified and experienced HVAC company. We recommend scheduling your service appointment in the fall season. This will allow you to have your furnace restored and functioning efficiently before you need it to warm up your home during the winter. On the other hand, scheduling your service appointment in the early autumn will provide you with sufficient time to address any issues that arise throughout your appointment.

Despite this, if you haven’t had your home’s furnace expertly maintained in quite a while, house owners should schedule an appointment to make sure their heating unit is operating at peak efficiency. This will not only provide you with reassurance until your next appointment, but it will also assist you in saving money over the long term by avoiding costly repairs that are inconvenient to deal with later on.

Is it time to service your home’s heating system? If you answered yes, the crew at 669-Heat is here to help! 669-Heat is available around the clock, 365 days a year. If homeowners need a repair, maintenance, or installation appointment after normal office hours, on weekends, or on holidays, there will be no added cost.

Furthermore, Sudbury, Ontario residents who work with the team at 669-Heat to remove their current heating system will also have access to our business’s variety of payment plans with options of up to $3000 in savings, that include no expenses for 12 months at 0% interest. As an outcome, you can put in a new heating system without paying any costs during the first year. Furthermore, if you need a new furnace throughout a severe winter, the 669-Heat service tech team is happy to provide property owners with same-day or next-day installations on all heating systems in emergency situations.

How often should furnace filters be changed in Sudbury?

In general, homeowners should aim to have their furnace filters cleaned once every three months. This is because as you use your furnace throughout the year, it collects dust, hair, dirt, and other debris that can not only cause damage to your overall equipment but also cause your home to be very dusty.

As such, you may experience prolonged allergy-like symptoms and other respiratory illnesses. At the same time, if you have a larger family and pets, you may wish to replace or clean your furnace filter more frequently as the amount of hair and other debris that is collected will be heightened.

When was the last time you cleaned or replaced your furnace filter? If you can’t remember, we recommend homeowners book a maintenance appointment with the team at 669-Heat! We’ll have a technician come to your home and ensure your furnace system is back up and running optimally for you and your heating needs in no time!

Furnace Maintenance FAQs

Furnace maintenance is an important part of preparing for fall & winter.

Getting ready for the chillier months (not to mention the downright frozen ones) means making sure your home’s heating system is ready to run at top quality to keep you comfortable from autumn until April.

A tune-up is essential because it allows our HVAC technicians to check for any issues with core components of your furnace – heat exchanger, igniter & pilot lights, burners, gas valve, thermocouple, flame sensor, draft inducer motor, pressure switch, blower motor & return air filter.

Any issues that may hinder your furnace’s performance can then be addressed, ensuring there are no interruptions to your home comfort throughout the colder months.

The proactive nature of furnace maintenance also means you can avoid nasty, expensive, middle-of-the-night repairs during a classic Canadian cold snap, giving you peace of mind all winter long.

Furnace maintenance can help you identify any potential problems with your home’s heating system before they cause a breakdown, which means you’ll avoid the cost of any future repairs that may have resulted from letting the problem persist.

These potential savings are a main reason it’s a good idea to get a furnace tune-up in the late summer or early fall months: act now so you don’t have to pay more later.
