HVAC Company Serving Ellisville, MO

Ellisville grew steadily through the 1970s, 1980s, and 1990s, which means its housing stock is genuinely mixed: ranch homes near Kiefer Creek Road and Hutchinson Road sitting alongside newer two-story builds in subdivisions like Regal Pines Meadows and Clayton Trails. That spread matters for HVAC work, because a system built for a 1978 ranch does not age or fail the same way as equipment installed in a 2005 colonial, and neither gets a useful answer from a one-size-fits-all repair quote.

Martin-Jetco Heating and Air Conditioning has served West County homes since 1964, family-owned and operated through six decades. Licensed, NATE-certified technicians handle every visit, and the recommendation you get is tailored to your home’s needs.

What HVAC Replacement Costs in Ellisville

The majority of residential replacements in Ellisville fall into two ranges:

• Air Conditioner & Evaporator Coil Replacement: approximately $5,500 to $9,200
• Complete HVAC System Replacement: approximately $8,450 to $22,990+

What moves a project toward the higher end:

• Larger or multi-level floor plans that require more tonnage
• Ductwork that needs repair, sealing, or replacement
• High-efficiency, variable-speed equipment with a strong SEER2 rating
• Zoning systems for homes where different areas need separate temperature control
• Electrical or code updates required before installation
• Indoor air quality upgrades added to the project
• Tight or difficult equipment access

For Ellisville homeowners, an AC replacement typically runs approximately $5,500 to $9,200 for the air conditioner and evaporator coil, while a complete system replacement generally ranges from approximately $8,450 to $22,990 or more. Homes that have grown through finished basements, attic conversions, or additions often have ductwork that no longer matches the home's actual layout, which can shift projects toward the higher range.

An in-home evaluation is the only way to get a number tied to what your home actually calls for. Book one online or call (636) 205-1631.

What Common Repairs Cost: A Reference

If you are weighing a repair estimate against replacement, here are the typical ranges for the most common HVAC fixes:

• Capacitor: $150 to $450
• Thermostat: $100 to $600
• Ignitor replacement: $180 to $350
• Flame sensor: $180 to $340
• Furnace capacitor: $150 to $350
• Blower motor: $500 to $1,400+
• Evaporator coil: $600 to $2,000
• Control board: $700 to $1,650
• Heat exchanger: $2,000 to $4,000
• Compressor-related failures: well over $1,000

A repair that approaches a third of what a new system costs rarely makes financial sense over the next few years. When the numbers point that direction, our NATE-certified technicians will say so directly.

Why Ellisville's Housing Mix Creates Distinct HVAC Problems

Ellisville's growth across multiple decades produced a city where the HVAC challenges vary by neighborhood and by era of construction:

• 1970s and 1980s homes with original ductwork still in place. Metal duct joints from this era have gone through decades of thermal cycling and frequently develop gaps where conditioned air escapes into attic spaces before reaching living areas. The system compensates by running longer, which accelerates component wear and drives up energy bills.
• Late 1980s and 1990s homes with equipment that is decades overdue. Many Ellisville properties from this period have systems that are 25 to 30 years old. At that age, a repair estimate almost always tips the decision toward replacement. The cost of fixing aging equipment rarely justifies itself when the unit has that many years and that many miles on it.
• Condenser units working harder than the thermostat suggests. Ellisville's established neighborhoods and significant tree cover keep ambient humidity elevated around outdoor equipment during summer. A condenser unit surrounded by dense plantings or heavy shade operates in conditions harder than what the indoor reading implies.
• Additions and finished lower levels outside the original duct design. As Ellisville homes have been updated over the decades, finished basements and rear additions have added living space without always adding ductwork. These areas rely on whatever conditioned air drifts their way, which is rarely enough.
• Upper-floor heat accumulation in newer two-story builds. Homes in Regal Pines Meadows, Clayton Trails, and comparable developments tend toward open floor plans and two-story layouts where upper levels accumulate heat all summer. Ductwork that was sized for a simpler layout often cannot deliver enough supply air to the second floor to close the gap.
• Short-cycling and indoor humidity. A system that starts and stops too frequently never runs long enough to pull moisture out of the air. The house reads cool but feels damp.

Frequently Asked Questions

What zip codes does Martin-Jetco Heating and Air Conditioning serve in Ellisville?

All of Ellisville, including the 63011 and 63021 zip codes, plus the neighboring West County communities.

How much does a new HVAC system cost in Ellisville?

An AC replacement with evaporator coil typically runs $5,500 to $9,200. A complete system — furnace, air conditioner, and coil — runs $8,450 to $22,990 or more. Ductwork condition, home size, efficiency level, and installation complexity are the main variables. Request an estimate online or call (636) 205-1631 for a number tied to your specific home.

My Ellisville home was built in the 1970s or 1980s. What should I plan for?

Homes from that period commonly have ductwork that has never been sealed or balanced, electrical panels that may need updating before new equipment can be installed, and insulation that falls short of what modern high-efficiency systems are designed to work with. The evaluation identifies all of that before the project is priced so the estimate reflects the actual scope.

How much does AC repair typically cost in Ellisville?

Minor AC repairs such as capacitors ($150 to $450) and thermostats ($100 to $600) fall on the lower end. Blower motors run $500 to $1,400 or more, evaporator coil repairs $600 to $2,000, and compressor-related failures can exceed $1,000 by a wide margin. Martin-Jetco Heating and Air Conditioning explains the repair cost and how it compares to a replacement before any work is authorized. Call (636) 205-1631 to book a service visit.

How much does furnace repair typically cost in Ellisville?

Ignitor replacement runs $180 to $350, flame sensor cleaning $180 to $340, and a furnace capacitor $150 to $350. Blower motors are $500 to $1,400 or more, control boards $700 to $1,650, and heat exchangers $2,000 to $4,000. Repairs in the control board or heat exchanger range are usually worth comparing directly against a furnace replacement. Call (636) 205-1631 and a NATE-certified technician will walk you through the options after diagnosing the problem.

My AC is running but the house is not cooling. What is going on?

Possible causes include a dirty filter, low refrigerant, a frozen evaporator coil, a failing capacitor, a clogged outdoor condenser, ductwork leaks or gaps, thermostat issues, or a system too old to handle Missouri summer humidity. In Ellisville, condenser units surrounded by dense landscaping can also be working against elevated heat and humidity that the indoor thermostat does not reflect. 

What causes a furnace to blow cold air?

Cold air from a running furnace typically points to a dirty filter, thermostat problem, ignition failure, flame sensor fault, gas supply issue, tripped limit switch, or control board fault. The blower can continue running after the burners shut down, which is why the air feels cold even when the system appears to be on. Because these involve gas and combustion components, call (636) 205-1631 rather than resetting and waiting. A technician will identify the fault and confirm the system is safe before returning it to service.

Do heat pumps hold up in Missouri winters?

Modern heat pumps are built to perform in climates like Missouri's, and the technology has improved significantly from older designs. They work well through mild and moderate winter temperatures, and some newer models handle colder stretches better than previous generations did. For Ellisville homes with higher peak heating loads, a dual-fuel pairing may be the better configuration. Martin-Jetco Heating and Air Conditioning evaluates ductwork, insulation, energy use, and comfort goals before pointing in either direction.

What does an HVAC maintenance schedule look like?

Two visits per year is the baseline: one in spring to prepare the cooling side and one in fall to ready the furnace. Documented HVAC Maintenance also satisfies most manufacturers' warranty requirements. In Ellisville, where older homes with aging ductwork and dense tree cover tend to put more than average demand on equipment, staying on a consistent schedule tends to show measurable benefits.

How long does a replacement installation take?

Most single-system replacements are completed in one day. Ductwork corrections, zoning additions, or electrical work can extend the timeline, and Martin-Jetco Heating and Air Conditioning gives a clear estimate of how long before any work starts. Contact us online or call (636) 205-1631 to schedule.
