Furnace Maintenance

Why Is Furnace Maintenance Important?

Many furnaces break down because of lack of maintenance. Similar to how your car should get an oil change, your furnace should receive a tune-up once per year. When you schedule an annual heating tune-up, you could see:
Increased efficiency – As part of our inspection checklist, we will make sure your furnace is working at its peak performance levels to ensure it can reach maximum power efficiency.
Lower energy bills – One of the first signs your unit isn’t working properly is a spike in monthly energy bills. Annual maintenance ensures your unit is clean and not working harder than it needs to.
Longer lifespan – When you schedule annual maintenance, you can expect your unit to last longer with fewer major breakdowns.
Fewer breakdowns – Many common breakdowns can be avoided if the unit was properly taken care of. Avoid costly breakdowns and schedule annual maintenance.
