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

If your heater is under 10 years old and the repair cost is less than half the price of a new system, repair is usually the right call. For systems over 15 years old, heater replacement typically makes more financial and practical sense, especially after multiple repairs. Older systems also run less efficiently, meaning you may be paying more in energy costs each month than a newer unit would require. At some point, the ongoing expense of repairs and higher utility bills outweighs the cost of a new system. A few specific factors to weigh: the age and condition of your system, how often it has needed service in the past two seasons, whether replacement parts are still readily available, and whether your energy bills have been climbing without a change in usage. An Aire Serv service professional can walk you through a repair-versus-replacement comparison with clear, upfront pricing. Contact your local Aire Serv to schedule an on-site assessment before committing to either option.

What size heater do I need for my home?

The right heater size is determined by a professional load calculation, not just by square footage alone. A unit that’s too small won’t keep up during cold weather, leaving rooms uncomfortable. One that’s too large will short-cycle, switching on and off too frequently, which wastes energy and causes unnecessary wear on the system over time. Load calculations account for your home’s square footage, insulation quality, ceiling height, number of windows and doors, local climate, and sun exposure. Two homes with the same square footage can require significantly different systems based on these variables. Your local Aire Serv service professional will conduct this inspection before recommending any system, so your heater installation is sized correctly from the start. Contact your local Aire Serv to schedule a home evaluation.

How long does a heater installation take?

Many standard heater installation jobs can be completed in a single day, though timelines vary by system type, home setup, and installation requirements. The total time depends on the type of system being installed, whether ductwork or venting modifications are needed, and how accessible your existing equipment area is. More involved projects, such as switching from one system type to another or adding new ductwork in a home that didn’t previously have it, may take longer. Your service professional will review the full scope of work with you before the job begins. Once installation is complete, your Aire Serv service professional will walk you through how to operate the new system, test everything to confirm it’s running properly, and answer any questions you may have.

What should I do to prepare for heater replacement?

Before your scheduled heater replacement appointment, clear the area around your existing unit so the service professional has safe, unobstructed access to work. A little preparation helps the job go smoothly and can reduce the total time on site. It also gives you a chance to think through any questions or preferences before the service professional arrives. A few things to handle ahead of time: remove any items stored near your current unit, confirm the thermostat is accessible, note any performance issues you want to mention, and make sure children and pets are kept away from the work area during the installation. If you have a preferred system brand or energy efficiency rating in mind, let your local Aire Serv know in advance so we can confirm availability. After installation, your service professional will test the system, verify proper airflow and performance, and review warranty details with you.

Does Aire Serv offer financing for heater installation?

Yes. Many local Aire Serv franchises offer financing options to help make heater installation more manageable. Financing can help spread out that cost so you can get a reliable, efficient system installed now rather than delaying through another heating season with an aging unit. Available financing options, terms, and qualifying requirements vary by location, since each Aire Serv franchise is independently owned and operated. Some locations may also have access to manufacturer rebates or energy efficiency incentives that can further reduce the upfront cost. Contact your local Aire Serv to ask about financing options available in your area. Your service professional can also walk you through any applicable rebates or tax credits that may apply to your new system.

Most home heating systems last between 15 and 20 years. If yours is in that range and breaking down more often, heater replacement may be the more reliable and cost-effective path. An aging unit may lead to higher energy use, inconsistent comfort, and more frequent or costly repairs.

A service professional from your local Aire Serv can inspect your system and walk you through your options clearly. Common signs it may be time to replace: your heater struggles to reach your set temperature, energy bills have climbed without a change in usage, or you’ve needed repairs more than once this season.
A proper heater installation depends on accurate sizing, correct venting, and thorough testing. An undersized unit won’t heat your home effectively, and an oversized one will cycle on and off too often, wasting energy and wearing out the system ahead of schedule.

Aire Serv service professionals are trained to evaluate your home’s heating load, recommend the right system for your needs, and complete every heater installation to manufacturer specifications. Every job is backed by the Neighborly Done Right Promise®, so you can feel confident from the first call to the final test.
A new heater installation is worth protecting. Routine maintenance can help support efficient performance, catch small issues early, and promote longer equipment life. Ask your local Aire Serv service professional about Advantage Plan Membership options available in your area.
