American Mechanical Systems is an Armstrong Air Authorized Dealer serving Naperville and the surrounding communities. As a factory authorized dealer, we install the complete Armstrong Air line of gas furnaces, air conditioners, air handlers, and indoor air quality products, all backed by our own workmanship guarantee.
Every Armstrong Air furnace is built with EHX Technology, a patented heat exchanger design engineered to eliminate hot spots that shorten furnace life and to put more air in contact with the heat exchanger surface for stronger, more efficient heat transfer. It is one of the reasons we stand behind this equipment for the homes and businesses we serve throughout Naperville.
Pair an Armstrong Air furnace with a matching Pro Series air conditioner or heat pump and a Comfort Sync thermostat, and you get a fully coordinated system built to work together instead of a mismatched collection of parts.
The Armstrong Air Pro Series furnace lineup covers a range of budgets and comfort goals, from dependable single-stage models to fully modulating, whisper-quiet systems.
The A802VK is the Pro Series model we install most often in this tier. It carries an 80% AFUE rating, a Comfort Sync enabled control board, and a proprietary motor design that separates the blower motor from its control unit, so a future repair only means swapping the failed part instead of the whole assembly. That keeps long-term service costs down for Naperville homeowners who want a simple, dependable furnace.
The A972VK carries a 97% AFUE rating and ENERGY STAR certification, and it can run in a dual-fuel setup alongside an all-climate heat pump, automatically switching between gas and electric heat depending on the outdoor temperature. It is the model we recommend most for Naperville households that want noticeably steadier comfort without moving all the way up to a fully modulating furnace.
The A98MVK is Armstrong Air's top-tier furnace, using a modulating gas valve that adjusts heat output in increments as small as 5% rather than firing at full capacity on every cycle. Combined with a fully variable-speed blower, it is ENERGY STAR certified and built to pair with an all-climate heat pump for maximum dual-fuel savings, a strong fit for larger Naperville homes that run heat hard through the winter.
Whether you run your air conditioner around the clock all summer or only on the hottest days, there is an Armstrong Air system sized and staged to match how you actually live.
The A7AC13F is rated at 13.4 SEER2 and up, built around a single-stage scroll compressor with Omniguard corrosion protection on the outdoor coil and a heavy-duty compressor blanket that keeps operating noise down. It is a straightforward entry point for homeowners replacing an aging unit on a tighter budget.
The A7AC14F reaches 14.3 SEER2 and up and uses the same MHT Technology found across the Armstrong Air lineup, with lanced coil fins and rifled tubing that improve heat transfer at the coil. When it is matched with a variable-speed furnace or air handler, the combined system can, in many cases, reach an even higher SEER rating than the outdoor unit carries on its own.
The A7AC22V uses a true variable-capacity, inverter-driven compressor that reaches up to 22 SEER2, adjusting output gradually instead of switching abruptly on and off. That gives roughly 50% lower noise levels than a 10 SEER single-stage unit and noticeably better humidity control through Naperville's muggy summer stretches, especially when paired with the Comfort Sync A3 Thermostat for remote access and an away mode that saves energy while you are out of the house.
For homes with electric heat, heat pump systems, or a furnace-free setup, Armstrong Air handlers pair a variable-speed or constant-torque blower with Omniguard corrosion protection to move conditioned air efficiently and quietly throughout your home. We size and install the model that best matches your equipment and budget.
The 7AH1AE uses a constant-torque blower motor that holds airflow steady where a standard single-speed motor would taper off as static pressure builds, which keeps comfort more even from room to room. It carries Omniguard Total Corrosion Protection Technology, an anti-microbial drain pan, and MHT Technology coils with rifled tubing for better heat transfer, plus a 10-year limited parts warranty. It is the option we recommend most for Naperville homeowners who want a reliable, budget-conscious air handler to pair with a heat pump or electric furnace.
The 7AH1AV steps up from the 7AH1AE with a fully variable-speed blower motor that ramps airflow up and down to hold temperature and humidity steadier throughout the day, while still fitting in the same compact single-piece cabinet. It adds an insulated cabinet for lower motor noise, the same Omniguard corrosion protection and anti-microbial drain pan, and supports dealer-installed heat strips for supplemental heat on the coldest days, backed by a 10-year limited parts warranty.
The 7AH2AV is built around the same variable-speed motor as the 7AH1AV but adds a stronger two-piece cabinet for greater structural rigidity, Comfort Sync A3 thermostat compatibility for remote access and five-day weather alerts, and Pro Series pairing with a matched heat pump or air conditioner. It is the air handler we install most often for larger Naperville homes that want a fully coordinated, app-controlled comfort system rather than a standalone blower.
Armstrong Air furnaces are backed by a limited lifetime warranty on the aluminized steel heat exchanger, giving you long-term protection on one of the most important components in your system.

It depends on budget and how hard you run cooling through the summer. The A7AC13F and A7AC14F are single-stage units built for straightforward, economical cooling, while the A7AC22V's variable-capacity compressor is worth the extra upfront cost for homes that want quieter operation and tighter humidity control during long stretches of hot weather. Our AC installation team can size the right unit for your home during a free estimate.
