HVAC Company Serving Creve Coeur, MO

Many of Creve Coeur’s homes were built in the 1970s, which puts many of them at a turning point for HVAC service. Some still have original ductwork or older electrical panels, while others have systems that have already been replaced once and may be nearing the end of their service life.

Newer condos along Olive Boulevard and later-built gated communities bring a different set of HVAC concerns, from equipment access to comfort control in larger or more complex layouts. Martin-Jetco Heating and Air Conditioning has served Creve Coeur and the surrounding St. Louis area since 1964, and our family-owned team takes the time to look at the home, the system, and the layout before recommending a repair, replacement, or upgrade.

If a system in your home is running poorly or simply aging out, the right starting point is a clear diagnosis from a licensed, NATE-certified technician. Call (636) 205-1631 or contact us online.

HVAC Replacement Cost Ranges

Two price ranges cover most residential HVAC replacements in Creve Coeur:

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

What drives a project toward the upper range:

• Larger single-family homes or properties with additions and finished lower levels
• Ductwork that requires sealing, resizing, or full replacement
• High-efficiency, variable-speed equipment chosen for long-term energy savings
• Zoning systems that allow different areas of the home to be controlled separately
• Electrical or code updates needed before modern equipment can be installed
• Indoor air quality equipment added to the project scope
• Tight access points that make installation more involved

For Creve Coeur homeowners, an AC replacement with an evaporator coil typically runs approximately $5,500 to $9,200, while a complete HVAC system replacement generally falls in the $8,450 to $22,990 range or higher. 

In this city specifically, 1970s-era homes often need ductwork attention alongside the equipment itself, and condo buildings have their own installation variables that single-family estimates do not account for. Only a visit to the property produces a number you can rely on. Schedule an evaluation online or call (636) 205-1631.

What Repairs Cost: Numbers to Know Before You Decide

In our experience, these are the kinds of repair ranges homeowners often see once a technician has diagnosed the problem. The exact number depends on the system, the part, access to the equipment, and whether the issue is isolated or tied to a larger failure.

Common repair ranges include:

• 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 (Over $1,000)

A repair is worth doing when the cost is reasonable relative to the system's remaining life. When a single repair runs close to a third of what a new system costs, putting that money toward a replacement usually makes more financial sense over the next several years. Martin-Jetco Heating and Air Conditioning walks through the math with you before recommending anything.

What Creve Coeur Homes Often Need from HVAC Service

Creve Coeur has a wide mix of homes, and many were built or expanded during decades when HVAC equipment, ductwork standards, and comfort expectations looked different than they do now. That does not automatically mean the system needs to be replaced. It does mean the home deserves a closer look before anyone recommends a repair, upgrade, or new installation.

Here are a few things our technicians often look for in Creve Coeur homes:

• Ductwork that may not match newer equipment. Many homes still rely on duct systems designed around older furnaces and air conditioners. When newer high-efficiency equipment is connected to undersized, leaky, or aging ducts, the system may not deliver the comfort or efficiency homeowners expected. 
• New equipment paired with old air distribution. It is common to see a furnace or AC that has been replaced while the ductwork was left untouched. The equipment may be the right size on paper, but the home can still have uneven rooms, weak airflow, or longer run times if the ductwork was never evaluated. 
• Condo and townhome installation limits. Creve Coeur condos and townhomes can bring different HVAC concerns than freestanding homes. Limited mechanical space, HOA requirements, shared building conditions, and access limitations can all affect how repairs or replacements are planned. 
• Humidity and indoor air comfort. Homes from the 1970s often sit between older draftier construction and newer tighter construction. That can contribute to summer humidity, winter dryness, or indoor air that feels stale when the HVAC system is not sized, balanced, or maintained well. 
• Homes that have changed over time. Additions, finished lower levels, and remodeled layouts can change what the HVAC system needs to handle. A system sized for the original floor plan may struggle once the home has more finished space or a different layout. 

If one of these sounds familiar, our NATE-certified technicians can take a closer look and explain what is happening in your home. Call (636) 205-1631 or schedule an HVAC evaluation online.

Ways to Make a New HVAC System More Manageable

A replacement estimate should show more than the equipment price. During your in-home evaluation, Martin-Jetco Heating and Air Conditioning looks at the programs that may help reduce the amount you pay upfront or spread the cost out over time.

Depending on the project, that may include:

• Financing for qualifying projects, so the cost can be divided into monthly payments without added interest 
• Spire rebates submitted for you when eligible equipment is installed 
• Federal energy-efficiency tax credits for qualifying heat pumps, furnaces, and AC systems 
• Seasonal offers that may be available at the time of your estimate 

Before you decide, you will see the full project cost, any payment options, and the savings that may apply to your system.

Maintenance That Helps Protect the System You Paid For

A new HVAC system is a major investment, and seasonal maintenance helps keep it running the way it should. The Martin-Jetco Heating and Air Conditioning Home Comfort Agreement gives homeowners a simpler way to stay ahead of wear, breakdowns, and warranty concerns.

Membership includes:

• Two seasonal visits each year, timed before summer cooling demand and winter heating season 
• A full equipment inspection at each visit, with small issues identified and explained before they become larger repairs 
• 20% off parts and labor on repair work needed between scheduled visits 
• No added overtime rate for evening or weekend calls 
• Priority scheduling when an unplanned repair comes up 
• A reduced diagnostic fee for service calls during regular business hours 
• Maintenance records that satisfy most manufacturer warranty requirements 

For Creve Coeur homes, especially those with older ductwork, replaced equipment, or additions added over the years, routine inspections can be especially useful. A technician can catch airflow, wear, safety, and performance issues before the system is under peak seasonal demand.

Frequently Asked Questions

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

Martin-Jetco Heating and Air Conditioning serves all of Creve Coeur, including the 63141 and 63146 zip codes, along with neighboring mid-county communities.

My Creve Coeur home was built in the 1970s. What tends to come up on these projects?

The most common issues are ductwork that was never updated when the system was replaced, electrical panels that may need work before modern equipment can be installed, and insulation that falls short of what current high-efficiency systems are paired with. The evaluation identifies all of that before the project is scoped so the estimate you receive reflects the full picture, not just the equipment.

Do you work on condo and townhome HVAC systems?

Yes. Creve Coeur has a significant condo population, and the installation in those units are different from single-family work. Martin-Jetco Heating and Air Conditioning handles condo and townhome HVAC across the city, including communities like Old Ballas Village and others along the Olive Boulevard corridor. Contact us online or call (636) 205-1631 to talk through what your unit needs.

How much does it cost to replace an HVAC system in Creve Coeur?

An AC replacement with evaporator coil runs approximately $5,500 to $9,200. A complete system replacement runs approximately $8,450 to $22,990 or more. Ductwork condition, home size, equipment type, and installation complexity are the main variables. Call (636) 205-1631 or request an estimate online.

How much does AC repair typically cost in Creve Coeur?

Capacitor repairs run $150 to $450 and thermostat issues $100 to $600. Blower motor replacements run $500 to $1,400 or more, evaporator coil problems $600 to $2,000, and compressor failures can significantly exceed $1,000. Martin-Jetco Heating and Air Conditioning gives you the repair cost and a replacement comparison before any work starts. Call (636) 205-1631 to schedule an AC assessment.

How much does furnace repair typically cost in Creve Coeur?
Ignitor replacement runs $180 to $350, flame sensor cleaning $180 to $340, and a furnace capacitor $150 to $350. Blower motors run $500 to $1,400 or more, control boards $700 to $1,650, and heat exchangers $2,000 to $4,000. Repairs in the heat exchanger or control board range are usually worth comparing directly against a furnace replacement. Call (636) 205-1631 to request a furnace evaluation.

Why is my AC running but the house is not getting cooler?

Several possibilities: a dirty filter, low refrigerant, a frozen evaporator coil, a bad capacitor, a fouled outdoor condenser, duct leaks, or a thermostat fault. In Creve Coeur homes where ductwork has not been updated since the 1970s, escaped conditioned air is a more common culprit than most homeowners expect. A technician needs to check refrigerant levels, measure airflow at the registers, and inspect the coil and condenser before any AC repair is confirmed.

What makes a furnace blow cold air?

The blower fan can stay running after the burners shut down due to a limit switch trip, control board fault, or ignition failure, which is why cold air comes out even when the system appears to be running. Other causes include a dirty filter, thermostat error, flame sensor failure, or gas supply interruption. Call (636) 205-1631 rather than resetting and hoping. A technician will identify the fault and verify the system is operating safely before leaving the home.

Are heat pumps practical for Creve Coeur homes?

For many properties, yes. Martin-Jetco Heating and Air Conditioning offers heat pump services for homeowners who want a single efficient system for both heating and cooling. The technology has improved considerably for Missouri's climate, and newer models handle cold-weather performance better than earlier generations did.

How often does an HVAC system in a 1970s home need servicing?

Twice a year is the standard, but the condition of the ductwork and equipment in older Creve Coeur homes often makes that schedule more important than it is for newer construction. HVAC maintenance visits also satisfy most manufacturers' warranty documentation requirements, which matters when you have invested in new equipment. Twice a year, before each season, is the right cadence.

What financing options are available?

Martin-Jetco Heating and Air Conditioning offers financing options for qualifying projects, and the team reviews applicable Spire rebates, federal energy-efficiency tax credits, and current seasonal offers during the evaluation. You see the complete cost picture, including monthly payment options, before committing to anything.
