HVAC Company Serving Maplewood, MO

Maplewood has a lot of older homes packed into a small city, and that can make HVAC work more complicated than it looks from the outside. Victorian homes, brick bungalows, Arts and Crafts houses, and newer townhomes all show up within the same 1.56 square miles. Some have older ductwork, some were updated in stages, and others had heating or cooling added long after the home was built.

Martin-Jetco Heating and Air Conditioning brings decades of hands-on experience with older St. Louis County homes, including systems that have been repaired, replaced, expanded, or reworked over time. That history helps the team look beyond the unit itself and recommend HVAC solutions that fit the home’s layout, age, airflow, and long-term needs.

What Does It Cost to Replace an HVAC System in Maplewood?

Two categories cover most residential replacements: 

• AC Replacement with evaporator coil: approximately $5,500 to $9,200
• Complete HVAC system (furnace and AC): approximately $8,450 to $22,990 or more

What affects where a Maplewood project lands:

• Square footage and system tonnage required
• Whether existing ductwork is usable or needs sealing, modification, or replacement
• High-efficiency variable-speed equipment versus standard equipment
• Zoning needs for homes where different floors or additions need independent control
• Electrical or code updates before installation can begin
• Indoor air quality components added to the project
• Access in tight construction, finished historic interiors, or constrained outdoor equipment spaces

In Maplewood, ductwork often significantly determines the final cost, because so much of it was added after original construction and has never been fully assessed. An AC replacement with evaporator coil typically runs approximately $5,500 to $9,200, while a complete HVAC replacement ranges from $8,450 to $22,990 or more, but the spread is wider here because of what a technician might find inside the walls. 

An in-home evaluation is the only reliable way to price the actual project. Schedule one online or call (636) 205-1631.

How Much Does It Cost to Fix an AC or Furnace?

When your AC or furnace breaks down, the cost depends on what failed and how much life the system has left. These common repair ranges can help you know what to expect before a technician confirms the issue:

• 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

After diagnosing the system, our NATE-certified technician gives you a firm cost and explains how it compares to AC Replacement or furnace replacement, so the decision is based on real numbers. Call (636) 205-1631 if you want a straight answer on whether the repair is worth it.

Making HVAC Replacement More Affordable

Most homeowners who call about a system replacement ask the same question first: is there a way to pay for this without a large upfront payment? The answer is usually yes, and Martin-Jetco Heating and Air Conditioning reviews every applicable option during your in-home evaluation.

• Financing is available for qualifying projects, converting the full cost into a fixed monthly payment.
• Utility rebates apply to eligible higher-efficiency equipment and are submitted by our team on your behalf at installation. You do not track them separately.
• Federal energy-efficiency tax credits are available on qualifying heat pumps and high-efficiency furnaces. The amount depends on the equipment and the tax year.
• Current seasonal promotions are worth asking about when you call (636) 205-1631, since they vary by time of year.

All of this gets reviewed alongside the equipment cost during your evaluation, so you see the full financial picture before making a decision.

Maintenance That Keeps Older Systems Running

In an older Maplewood Victorian or bungalow, seasonal maintenance can catch problems tied to aging equipment, added ductwork, limited access, or an unclear service history. A pre-season inspection helps find those issues before they turn into an emergency during the first cold week of November or the hottest stretch of July.

The Martin-Jetco Heating and Air Conditioning Home Comfort Agreement puts that inspection on a schedule that runs ahead of both peak seasons:

• Pre-season visits before cooling and heating demand arrive
• Full safety and performance check at each visit
• 20% off parts and labor on repair work between visits
• No extra charge for after-hours or weekend calls
• Priority scheduling when an unplanned issue comes up
• Reduced diagnostic fee on calls during regular business hours
• Service documentation satisfying most manufacturer warranty requirements

Why Maplewood Homes Present Specific HVAC Challenges

Maplewood homes can be harder to diagnose than newer homes because the heating and cooling setup is often layered onto older construction. A licensed, NATE-certified Martin-Jetco Heating and Air Conditioning technician looks at the full property before making a recommendation, including the age of the home, the ductwork, the equipment location, and any renovations that may have changed how the system performs.

These are some of the issues our technicians look for in local homes and buildings:

• Victorian and bungalow homes built before modern cooling existed. A significant share of Maplewood’s residential stock predates central air conditioning, which means the ductwork, if any exists, was added after the fact. Routing through original plaster construction and period woodwork limits the options and affects both the cost and the approach. 
• Ductwork pieced together over multiple renovation cycles. Many homes have had systems updated, expanded, or partially replaced at different points by different contractors. That can leave behind a duct system that works inconsistently.
• Tight urban lots with constrained outdoor equipment placement. Maplewood’s density leaves little room for outdoor condenser units. Units placed too close to structures, fences, or neighboring properties can run hot, cycle inefficiently, and wear components faster than a unit with adequate clearance. 
• Multi-family and mixed-use buildings throughout the commercial corridor. Properties along Manchester Road and the Greenwood Historic District often mix residential and commercial use, each with its own HVAC requirements, access limitations, and sometimes historic preservation considerations that affect where equipment can be placed. 
• Systems due for replacement in recently renovated homes. Maplewood’s real estate market has been active, with many properties renovated and resold over the past decade. A home that looks updated may still be running an older system that was never part of the renovation scope.

What zip code does Martin-Jetco Heating and Air Conditioning serve in Maplewood?

Martin-Jetco Heating and Air Conditioning serves all of Maplewood and the 63143 zip code, along with neighboring communities including Brentwood, Richmond Heights, and Webster Groves.

My home was built around 1910 or 1920. What does adding central air actually involve?

Homes from that era were built for natural ventilation and radiator heat, not central air. Adding AC usually means choosing between new ductwork, when attic or crawl space routing allows it, or ductless mini-splits, which cool rooms independently with minimal disruption to plaster walls and original woodwork. An in-home evaluation shows which option fits the property.

My Maplewood home has been renovated, but the HVAC system looks original. How do I know if it needs replacing?

Age alone is not the only answer, but it is a starting point. A system from the 1990s that has never been serviced consistently is in a different place than a 1990s system that has been maintained. Our in-home evaluation looks at the equipment's actual condition, its efficiency, whether it is producing the right airflow, and whether any components are showing signs of wear that indicate declining performance.

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

Replacement costs fall into two ranges:

• AC with evaporator coil: approximately $5,500 to $9,200
• Complete system (furnace and AC): approximately $8,450 to $22,990 or more

In Maplewood, where ductwork condition and equipment access vary considerably from one home to the next, the actual figure can move significantly within those ranges. Call (636) 205-1631 or request an estimate online.

How much does AC repair typically cost in Maplewood?

Component-level repair ranges:

• Capacitors, thermostats: $150 to $600
• Blower motors, evaporator coils: $500 to $2,000
• Compressor failures, control boards, heat exchangers: $700 to well over $1,000

Our NATE-certified technician confirms the exact cost after diagnosing the specific failure, then compares it against AC replacement before any work starts.

How much does furnace repair typically cost in Maplewood?

Common repair cost ranges:

• Ignitor and flame sensor: $180 to $350
• Furnace capacitor: $150 to $350
• Blower motor: $500 to $1,400+
• Control board: $700 to $1,650
• Heat exchanger: $2,000 to $4,000

At the control board and heat exchanger level, furnace replacement deserves a direct comparison before committing to the repair. Call (636) 205-1631 for a diagnostic visit.

Certain rooms in my home never reach the right temperature. What causes that in an older home?

In a home where ductwork was added after original construction, the routing often reflects what was possible at the time rather than what was optimal for the floor plan. Runs that are too long, too narrow, or that make unnecessary turns can leave specific rooms consistently underserved. It can also come from gaps and separations at duct joints that have developed over years of seasonal expansion and contraction. A technician should measure airflow at each register and trace the duct layout before recommending whether the fix is a repair, a rebalancing, or a zoning change.

My furnace heats for a few minutes, then shuts off before the house reaches temperature. What is happening?

A furnace that starts and stops short of completing a full heating cycle is almost always reacting to a safety shutdown. The most likely cause is a dirty or clogged filter restricting enough airflow that the heat exchanger overheats and trips the limit switch. Replacing the filter and letting the system cool down resolves it if that is the only issue. If the short-cycling continues after a filter change, the limit switch itself may be failing, the heat exchanger may have a crack, or a control board fault may be interrupting the cycle. A cracked heat exchanger is a safety concern, not just a performance issue, so call (636) 205-1631 if the problem persists.

Are heat pumps a good option for Maplewood homes?

Modern heat pumps handle Missouri winters considerably better than older heat pump models. The question is whether the existing ductwork can distribute conditioned air effectively enough for a heat pump to perform at its rated efficiency. Homes where ducts were informally added or never balanced may have distribution gaps that limit the benefit.

How often should HVAC systems in Maplewood be serviced?

Twice a year: before cooling season and before heating season. In Maplewood specifically, where homes can have ductwork from different eras, equipment that has changed hands multiple times, and construction that makes access more involved than in newer homes, pre-season inspections tend to surface problems earlier than they would in a more standard environment.

Is financing available for HVAC work in Maplewood?

Yes. Financing is available for qualifying projects. Our evaluation also covers rebates, applicable federal energy-efficiency tax credits, and any current seasonal promotions. You have the full cost picture before deciding.
