How do I know if I need furnace replacement or repair?

Furnace replacement may be worth considering if your system is more than 15 years old, needs frequent repairs, has rising energy costs, or struggles to maintain a consistent temperature. As furnaces age, they lose efficiency and cycle through parts more often. Even if individual repairs seem minor, over time, repeated repairs may make replacement the better long-term option. A few signs that point toward replacement: repair costs that keep adding up, energy bills that have risen without a change in usage, and a furnace that struggles to maintain a consistent temperature. If your system is under 10 years old and well-maintained, a repair may be all you need. An Aire Serv service professional can evaluate your current system and provide a clear recommendation based on your system, home, budget, and comfort needs. Contact your local Aire Serv to schedule an assessment.

How long does furnace installation take?

Many standard furnace installation appointments are completed in four to eight hours. A straightforward swap of a same-size, same-fuel-type system is often finished in a half-day. The timeline depends on several factors, including the type of furnace being installed, the condition of your existing ductwork, and whether any code-required modifications are needed. If the job requires ductwork changes, new venting, or an electrical upgrade, the project may run into a full day or require a follow-up visit. Your service professional will walk you through the expected scope before work begins. To get an accurate timeline for your home, contact your local Aire Serv for an on-site assessment before scheduling the installation.

What size furnace does my home need?

Furnace size is measured in BTUs (British Thermal Units), and the right size depends on your home’s square footage, ceiling height, insulation level, window area, and local climate. A furnace that is too small will struggle on the coldest days, while one that is too large will cycle on and off too quickly, which wastes energy and puts extra wear on the equipment. Aire Serv service professionals use a heat load calculation, called Manual J, to determine the right furnace size for your specific home. This calculation accounts for all the variables that affect your heating needs. Reach out to your local Aire Serv for a proper sizing assessment before purchasing a new system. Proper sizing can help support better efficiency, comfort, and long-term system performance.

How can I extend the life of my new furnace?

Routine maintenance is the most effective way to keep your new furnace running efficiently and extend its service life. Annual professional tune-ups can help reduce breakdown risk, support efficient performance, and promote longer equipment life. Between professional visits, change the air filter every one to three months, keep vents and registers clear of furniture or obstructions, and call for service if you notice unusual sounds, smells, or a sudden change in heating performance. Ask your local Aire Serv about a maintenance plan that helps keep your furnace running efficiently year after year.

Signs It’s Time for Furnace Replacement

Many furnaces last 15 to 20 years with routine maintenance. If yours is approaching that age and repairs are becoming more frequent or costly, furnace replacement may be the smarter investment. Other signs include rising energy bills, uneven heating throughout your home, or a unit that keeps shutting off before reaching your thermostat setting.

If repair costs are approaching the cost of a new system, furnace replacement may help reduce energy use, improve comfort, and limit the need for ongoing service calls. An Aire Serv service professional can assess your current system and give you an honest recommendation.

Proper furnace installation starts before the equipment arrives. Our service professionals evaluate your home’s square footage, insulation, ductwork condition, and fuel source to identify the right system size. An oversized or undersized furnace won’t heat your home efficiently, and it wears out faster.

On installation day, your service professional will remove the old equipment, install the new system, test all connections, and perform a full startup check. Before the job is complete, we’ll walk you through basic operation so you know what to expect from your new furnace. Explore the complete range of Aire Serv heating services to find the right solution for your home.
