HVAC Company Serving Town & Country, MO

In a large Town & Country home, comfort is rarely a single-thermostat affair. Many estates here run on more than one heating and cooling system, splitting the main level, the upper floors, a finished lower level, a guest house, or a pool house into separate zones. When one of those systems starts to fade, the goal is even comfort throughout the whole property.

Family-owned and operated since 1964, Martin-Jetco Heating and Air Conditioning handles that, from a single repair to coordinating the replacement of several systems across one property, with licensed, NATE-certified technicians on every job.

Repair now, replace later, or stage the work over time — we’ll help you choose the practical path. Call (636) 205-1631 or message us onlineto schedule service.

How Much Does HVAC Replacement Cost in Town & Country?

When repair no longer makes sense, replacement in Town & Country generally falls into two ranges:

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

Factors that affect HVAC replacement pricing:

• Home square footage
• System tonnage requirements
• SEER2 efficiency rating
• Single-stage vs variable-speed equipment
• Existing ductwork condition
• Zoning systems
• Electrical or code upgrades
• Indoor air quality add-ons
• Accessibility of installation area

For Town & Country homeowners, an air conditioner and evaporator coil replacement typically runs approximately $5,500 to $9,200, while a complete HVAC system replacement generally ranges from approximately $8,450 to $22,990+. The final cost depends on the size of the home, the equipment selected, SEER2 efficiency, ductwork condition, zoning needs, electrical or code updates, indoor air quality upgrades, and how easy each system is to access.

In a home with more than one system, each is quoted separately, and replacing more than one at the same time can simplify scheduling and keep the equipment matched. Martin-Jetco Heating and Air Conditioning's NATE-certified technicians review available rebates, federal energy-efficiency tax credits, and financing during the visit, so the full cost and any savings are clear before you decide.

What Larger Town & Country Properties Often Need

Town & Country's larger custom homes and multi-level estates place more demand on heating and cooling equipment than a standard single-system setup can comfortably handle. When Martin-Jetco Heating and Air Conditioning evaluates a property here, the focus is the whole home, not one unit in isolation. Common needs include:

• Multiple HVAC systems. Many estates run two, three, or more systems, each responsible for a separate wing, level, or structure. Keeping those systems matched in age, efficiency, and capacity matters for even comfort across the whole property.
• Staged replacements. When systems are aging at different rates, replacing everything at once is not always the practical or financially sensible choice. Martin-Jetco Heating and Air Conditioning helps homeowners plan a phased approach that addresses the most urgent system first while accounting for what comes next.
• Zoning and airflow balancing. Larger floor plans, high ceilings, and open layouts can create temperature inconsistencies from one area to the next. Zoning systems and smart thermostats give each level or wing its own schedule, and variable-speed equipment holds steadier temperatures with less noise.
• Finished lower levels. A finished basement or walkout lower level often has different comfort needs than the main living area above it, and an undersized or poorly zoned system can leave it consistently warmer or cooler than the rest of the house.
• Guest houses and pool houses. Detached structures are often best served by a ductless mini-split that heats and cools the space independently, without extending the main home's duct system into a separate building.
• Detached garages and workshops. Like guest houses, these spaces need their own comfort solution, especially when they are finished, heated, or used as a home office or studio.
• Whole-home humidity control. Missouri summers bring heavy humidity indoors, and winters bring dry air that affects comfort, woodwork, and indoor air quality. A whole-home humidifier or dehumidifier integrated with the HVAC system keeps levels consistent throughout the year.
• Advanced filtration and air purification. In a larger home with a higher volume of air moving through the system, whole-home filtration and air purification can meaningfully improve indoor air quality, reducing allergens, dust, and airborne particles across every room.

Comfort & Air-Quality Upgrades Worth Considering

A replacement is also a good moment to improve how the whole home feels, not only how warm or cool it runs. Options that suit local homes include:

• Variable-speed equipment that runs quietly and holds steadier temperatures than single-stage units
• Zoning and smart thermostats that give each level or wing its own schedule
• Whole-home humidifiers to ease the dry air that comes with Missouri winters
• Advanced filtration and air purification for cleaner air across a large floor plan

Protect Your Investment with the Home Comfort Agreement

A larger home with multiple systems has more to maintain, and the Martin-Jetco Heating and Air Conditioning Home Comfort Agreement keeps every unit on a consistent schedule without putting the burden on you to track it. The plan covers a spring tune-up before cooling season and a fall tune-up before heating season for each system, plus:

• Priority scheduling when you need service
• A discounted diagnostic fee on office-hours service calls
• 20% off parts and labor on service repairs
• No overtime fees
• A full safety and performance check at every visit
• Documented HVAC maintenance that satisfies most manufacturers' warranty requirements

For a property with two or three systems running year-round, staying ahead of seasonal maintenance is the most reliable way to avoid the kind of breakdown that leaves part of the house uncomfortable while the rest runs fine.

A Team That Knows Complex Home Comfort

Larger homes need more than a box-for-box equipment swap. They need a team that understands how each system interacts with the rest of the property. Martin-Jetco Heating and Air Conditioning has served St. Louis-area homeowners since 1964 and remains family-owned and operated, with extensive experience serving Town & Country homeowners specifically.

Every visit is handled by licensed, NATE-certified technicians. The team installs York, Goodman, Daikin, Carrier, and Trane, making it easier to match new equipment to existing systems or recommend the right replacement when one unit is ready to retire before the others. No high-pressure sales tactics come with any of it, and if something needs a second look after the job is done, the team comes back and makes it right.

More than 1,000 five-star Google reviews, an A+ rating with the Better Business Bureau, six Angie's List Super Service Awards, and recognition as a York Dealer of the Year many years running — the record is there to check.

Frequently Asked Questions

What zip codes do you serve in Town & Country? 

Martin-Jetco Heating and Air Conditioning serves all of Town & Country, including the 63017, 63131, and 63141 zip codes.

My home has more than one HVAC system. Do I have to replace them all at once?

No. If one system is failing and the others are in good shape, Martin-Jetco Heating and Air Conditioning can replace just that one and help plan for the rest over time. The main consideration is matching: pairing new equipment with the systems you keep helps the home perform more consistently, especially when each unit serves a different level, wing, or finished space.

Do you service the brand of equipment already in my home?

In most cases, yes. Martin-Jetco Heating and Air Conditioning services a wide range of equipment and installs York, Goodman, Daikin, Carrier, and Trane. When replacement makes sense, the technician can recommend equipment that works alongside the home's existing systems where that approach is practical.

Do you install HVAC for a guest house, pool house, or detached structure?

Yes. Detached spaces are often a strong fit for a ductless mini-split, which heats and cools the structure independently without extending the main home's system. Martin-Jetco Heating and Air Conditioning can also review other options depending on the structure, insulation, electrical capacity, and how the space is used.

How much does HVAC replacement cost in Town & Country?

An air conditioner and evaporator coil replacement runs approximately $5,500 to $9,200, while a complete HVAC system replacement runs approximately $8,450 to $22,990+. Home size, number of systems, tonnage, SEER2 efficiency, equipment type, ductwork condition, zoning needs, electrical or code updates, indoor air quality add-ons, and installation accessibility all affect where the estimate lands. In homes with more than one system, each is quoted separately.

How much does AC repair cost in Town & Country, MO?

AC repair costs vary depending on the problem. Minor repairs such as capacitors ($150 to $450), contactors, or thermostats ($100 to $600) usually fall on the lower end. More involved repairs, including refrigerant leaks, evaporator coil problems ($600 to $2,000), or compressor-related failures, can run well over $1,000. In homes with multiple systems, the technician also reviews whether a pattern of repairs across one unit points toward replacement rather than continued service. Call (636) 205-1631 to ask about estimates.

How much does furnace repair cost in Town & Country, MO?

Furnace repair costs depend on the part, system age, and complexity of the work. Minor issues such as ignitor replacement ($180 to $350), flame sensor cleaning ($180 to $340), or basic electrical repairs usually cost less. More involved repairs, including blower motors ($500 to $1400+), control boards ($700 to $1650), or heat exchangers ($2,000 to $4,000), cost more and may point toward furnace replacement as the better long-term path. In a multi-system home, we can also help determine whether to repair one furnace now or coordinate the work with other planned replacements. Call (636) 205-1631 to discuss your options. 

How long does a new HVAC system last?

With regular maintenance, a quality HVAC system typically lasts 12 to 15 years, and some systems can last longer when they are properly sized, installed, and serviced. Town & Country homes with larger layouts, multiple zones, finished lower levels, or detached structures may place different demands on each system. Spring AC tune-ups, fall heating inspections, regular filter changes, clean coils, and prompt attention to small issues all help extend equipment life, improve efficiency, reduce breakdowns, and protect manufacturer warranty coverage.

Should I repair or replace my air conditioner?

Repair is usually the right call for a newer air conditioner with a single, isolated issue and a reasonable repair cost. Replacement makes more sense once the unit is 12 to 15 years old, still runs on R-22 refrigerant, needs repairs repeatedly, struggles with humidity, or faces a repair bill that approaches a third of the cost of a new system. In a home with more than one unit, Martin-Jetco Heating and Air Conditioning can help determine whether to replace one now, coordinate multiple replacements, or phase the work over time.

Why is my AC running but not cooling my Town & Country home?

An air conditioner that runs but does not cool may have a dirty air filter, low refrigerant, a frozen evaporator coil, a failing capacitor, a dirty outdoor condenser coil, ductwork problems, thermostat issues, or an aging unit that can no longer manage Missouri humidity. In larger Town & Country homes, the issue may also involve zoning, long duct runs, multiple systems, finished lower levels, or equipment that was never correctly sized for the area it serves. A technician should inspect the system, check refrigerant levels, measure airflow, and determine whether the issue is a straightforward AC repair or part of a larger comfort problem.

Why is my furnace blowing cold air?

A furnace may blow cold air because of a dirty filter, thermostat setting issue, pilot or ignition problem, flame sensor issue, gas supply problem, overheating limit switch, or malfunctioning control board. In some cases, the blower keeps running even though the burners are not producing heat. Because furnace problems can involve gas, combustion, and safety components, homeowners should not ignore the issue. Martin-Jetco Heating and Air Conditioning can inspect the furnace, identify the cause, explain the repair options, and confirm the system is operating safely before returning it to regular use.

Are heat pumps effective during Missouri winters?

Yes, modern heat pump services can be effective in Missouri's climate because they provide both heating and cooling in one efficient system. Heat pumps work especially well during mild and moderate winter weather, and many newer systems perform better in colder temperatures than older models did. For some Town & Country homes, particularly larger estates with higher heating demands, a dual-fuel setup or supplemental heat source may be recommended for the coldest days of the year. Martin-Jetco Heating and Air Conditioning can evaluate the home, comfort goals, insulation, ductwork, zoning, and energy usage to determine whether a heat pump is the right fit.

How often should HVAC maintenance be performed?

Most homes should have HVAC maintenance performed twice a year: once in the spring for the air conditioning system and once in the fall for the heating system. Homes with more than one HVAC system should have each unit checked on the same seasonal schedule so the full property is ready before peak demand. Regular maintenance improves efficiency, reduces unexpected breakdowns, extends equipment life, protects warranty coverage, and identifies small issues before they become expensive repairs.

How quickly can you respond to a breakdown?

Emergency HVAC service is available, including evenings, weekends, and holidays. Timing depends on the schedule, weather, technician availability, and the repair itself, but calling earlier gives Martin-Jetco Heating and Air Conditioning the best chance of reaching your Town & Country home the same day. Call (636) 205-1631 any time.

Need a Plan for One System or the Whole Property?

Whether one unit is fading, several systems are aging at once, or a detached space needs its own comfort solution, Martin-Jetco Heating and Air Conditioning can help you map out the smartest next step. Call (636) 205-1631 or schedule your in-home evaluation online today.
