Stop Reacting.
Start Preventing.

You've probably heard the saying, "They don't make them like they used to." We'd be dishonest if we said there wasn't some truth to that.

Older furnaces were often built with heavier steel and had fewer moving parts. However, modern furnaces offer significant advantages in efficiency, performance, and safety. Today's systems include numerous safety features that older furnaces simply didn't have.

There isn't a single "right" answer when it comes to furnace lifespan. Some furnaces are still operating after 20, 30, or even 40 years. That said, we generally consider 20 years to be a reasonable life expectancy for most furnaces.

Once a furnace reaches that age, it is often no longer covered by any parts warranty, and repair costs can begin to add up. If your furnace is more than 20 years old, one of the most important services you can schedule is a professional inspection. This allows a technician to verify that the heat exchanger is still safe and that the furnace can continue operating safely and reliably.

The frequency of filter replacement depends on several factors:

• Is your HVAC system used year-round, or only during certain seasons?

• What size filter do you have? A 1-inch filter typically requires more frequent replacement than a 5-inch filter.

• Do you live on a dirt road?

• Do you have pets?

These and other environmental factors can cause filters to become dirty more quickly.

As a general guideline:

• 1-inch filters: Check monthly. If the filter appears relatively clean, you may be able to extend the replacement interval. However, under normal operating conditions, a 1-inch filter should not be used for more than 6 months.

• 5-inch filters: Check after 6 months. If the filter still appears clean, you may be able to extend the replacement interval. However, a 5-inch filter should not be used for more than 12 months.

Keeping your filter clean is important for the health and efficiency of your HVAC system. Dirty filters restrict airflow and increase the system's external static pressure. Modern furnaces with variable-speed blower motors will often increase motor speed to compensate for this restriction, resulting in higher energy consumption and additional wear on the equipment. Over time, this can contribute to premature blower motor failure and unnecessary repair costs.

Every plan is built around your specific equipment, so nothing gets overlooked. For homeowners, that means two seasonal tune-ups per year — one in the fall to prep your furnace for heating season, one in the spring before cooling season kicks in. Each visit includes a safety inspection, efficiency test, filter evaluation, and a written service report you can keep for your records. Commercial plans cover rooftop units, split systems, refrigeration, and ventilation systems, and are designed to meet warranty and regulatory requirements as well.

Yes. We have plans tailored for homeowners as well as business owners and property managers. The residential plan focuses on seasonal tune-ups and home comfort, while commercial agreements are structured to reduce downtime, satisfy warranty requirements, and produce the documented service history that regulatory inspections often require. Contact us and we'll walk you through which plan makes sense for your situation.

Plan members receive priority scheduling, so you move to the front of the line when you need a service call — especially valuable during peak seasons when demand is highest. You'll also receive discounts on any repairs or service calls needed between scheduled visits. Combined with the efficiency gains and extended equipment life that come with regular maintenance, most members find the plan pays for itself many times over.

Yes — and this is especially important for commercial properties. Many equipment manufacturers require documented annual maintenance to keep warranties valid. Regulatory and insurance inspections may also call for a verifiable service history. Our commercial maintenance agreements produce exactly that: clear, written records of every visit that protect your warranty coverage and keep you prepared for any inspection.
