HVAC Company Serving Brentwood, MO

Brentwood packs a lot into two square miles. Mid-century Cape Cods and ranch homes sit close to newer townhouse construction and condo communities like Brentwood Forest, all within walking distance of the Promenade retail corridor and a short drive from three different interstates. That density means HVAC work here looks different than it does in a sprawling suburb: tighter lots, shared walls in condo and townhome buildings, and a housing stock old enough that a meaningful share of homes are on their second or third system since original construction.

Martin-Jetco Heating and Air Conditioning has worked on homes and businesses throughout this part of St. Louis County since 1964 and remains family-owned. A licensed, NATE-certified technician evaluates the actual property in front of them before recommending repair, replacement, or maintenance, never the other way around.

How Much Does HVAC Replacement Cost in Brentwood?

Replacement costs in Brentwood generally fall into two categories, though where your specific project lands depends on the home:

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

Several factors move a project up or down within those ranges:

• The square footage and tonnage the property requires
• Whether the existing ductwork needs sealing, resizing, or replacement
• Standard-efficiency equipment versus variable-speed, higher SEER2-rated systems
• Zoning needs, particularly in homes with finished lower levels or additions
• Electrical or code updates required ahead of installation
• Indoor air quality components added to the project
• Equipment access, which in Brentwood often means navigating tighter lots, shared walls, or condo association requirements

Condo and townhome projects in particular tend to involve different logistics than a detached single-family home in Brentwood, sometimes requiring coordination with an HOA or building management before work begins. 

An in-home evaluation accounts for all of it and gives you a number specific to your property. Schedule one online or call (636) 205-1631.

What HVAC Repairs Typically Cost

A repair estimate is easier to evaluate when you know the general range. Here is what the most common HVAC repairs run:

• 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 or more
• 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 technician confirms your exact cost once the specific part and labor are identified, and explains clearly whether that repair is worth making or whether AC replacement or furnace replacement is the better long-term value.

Savings Opportunities for Financing a New System

Brentwood's housing prices and density mean a lot of homeowners here are weighing a major equipment purchase against other home investments. Martin-Jetco Heating and Air Conditioning makes that easier with a few options reviewed during every in-home evaluation:

• Financing for qualifying projects, spreading the total into fixed monthly payments
• Spire utility rebates, filed on your behalf once eligible equipment is installed
• Federal energy-efficiency tax credits for qualifying heat pumps and high-efficiency furnaces
• Seasonal promotions, when available at the time of your estimate

Every option gets laid out clearly before you commit to anything, so you are comparing real numbers rather than guessing at what might apply.

For Same-Day & After-Hours Emergency Service, Call (636) 205-1631

In a city as compact as Brentwood, Martin-Jetco Heating and Air Conditioning can often get a technician to your door faster than you'd expect. Our emergency HVAC service runs around the clock, including evenings, weekends, and holidays, calls made earlier in the day frequently result in same-day appointments.

Every emergency visit starts the same way: the technician diagnoses the actual problem on site rather than guessing, walks you through what failed in plain terms, and gives you a firm repair cost before any work begins. Most repairs are finished during that same visit. Anything requiring parts or a longer timeline is typically resolved within 24 to 48 hours.

HVAC Considerations Unique to Brentwood

• Mid-century Cape Cods and ranch homes with original ductwork. A significant share of Brentwood's single-family stock dates to the years right after incorporation in 1929 through the postwar building years. Ductwork from that era was sized for older equipment, and pairing it with a modern high-efficiency system without an assessment limits what the new equipment can actually deliver.
• Condo and townhome HVAC in dense, shared developments. Communities like Brentwood Forest involve mechanical considerations a detached home does not: limited equipment placement, shared walls affecting noise and vibration, and often a condo association process before any work can start.
• Small lots with limited outdoor equipment placement. Brentwood's density means outdoor condenser units sometimes sit closer to property lines, neighboring structures, or shared spaces than they would in a larger-lot suburb, which can affect both installation options and airflow clearance requirements.
• Aging systems on properties that have changed hands multiple times. With home values in Brentwood climbing steadily and turnover relatively brisk, it is common for a property's HVAC history to be unclear to a new owner. A full system evaluation early in ownership often catches problems before they become emergencies.
• Commercial HVAC demand near the Promenade. Retail, office, and restaurant space near Brentwood Promenade and the Eager Road corridor has different load and downtime considerations than residential properties, and a failed system during business hours has severe financial consequences.

Frequently Asked Questions

What areas does Martin-Jetco Heating and Air Conditioning serve near Brentwood?

Martin-Jetco Heating and Air Conditioning serves all of Brentwood, including the 63144 zip code, along with neighboring communities including Maplewood, Richmond Heights, and Rock Hill.

Do you handle HVAC for condos and townhomes in Brentwood?

Yes. Communities like Brentwood Forest involve different considerations than a detached single-family home, including shared walls, limited mechanical space, and sometimes coordination with a condo association before work begins. Martin-Jetco Heating and Air Conditioning handles these projects regularly and accounts for those factors when scoping and pricing the job.

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

An AC replacement with evaporator coil runs approximately $5,500 to $9,200. A complete HVAC replacement runs approximately $8,450 to $22,990 or more. Property size, ductwork condition, equipment efficiency, and installation access all affect where your project lands. Call (636) 205-1631 or request an estimate online for a figure specific to your home.

What does AC repair typically cost?

Smaller repairs like capacitors and thermostats generally run $150 to $600. A blower motor replacement runs $500 to $1,400 or more, and an evaporator coil repair falls between $600 and $2,000. Compressor-related failures tend to be the most expensive single repair, often well past $1,000. Martin-Jetco Heating and Air Conditioning explains the actual cost and compares it honestly against AC replacement before any work begins.

What does furnace repair typically cost?

An ignitor replacement runs $180 to $350, a flame sensor $180 to $340, and a furnace capacitor $150 to $350. Larger repairs cost more: a blower motor $500 to $1,400 or higher, a control board $700 to $1,650, and a heat exchanger $2,000 to $4,000. At the higher end of that range, comparing the repair cost against furnace replacement is worth the conversation.

My home is older and I'm not sure when the HVAC system was last replaced. What should I do?

Given how often Brentwood properties change hands, this is a common situation. A full system evaluation can tell you the age and condition of your current equipment, whether the ductwork matches modern standards, and whether you are looking at routine maintenance or something more significant. It is worth doing early in ownership rather than waiting for a breakdown to find out.

Why does my AC run constantly without cooling the house properly?

Common causes include a dirty filter, low refrigerant, a frozen evaporator coil, a failing capacitor, a fouled outdoor condenser, or ductwork leaking conditioned air before it reaches the rooms that need it. In Brentwood's older homes, original ductwork that was never resized for modern equipment is a frequent and often overlooked factor. A technician needs to check refrigerant levels and measure airflow before confirming whether the fix is a simple AC repair or something larger.

My furnace is running but only blowing cold air. What's happening?

This usually means the blower fan is operating while the burners are not producing heat, which can result from a tripped limit switch, a control board fault, an ignition failure, or a flame sensor too dirty to register correctly. A clogged filter can trigger the same response by causing the system to overheat and shut down the burners as a safety measure while the fan continues running. Because gas and combustion components are involved, call (636) 205-1631 rather than repeatedly resetting the system.

Are heat pumps a good option for Brentwood homes?

For many properties, yes. Heat pumps combine heating and cooling into a single system, and today's equipment performs significantly better in Missouri winters than older heat pump models. Whether a heat pump alone covers your needs or you would benefit from a dual-fuel setup with backup furnace heat depends on your home's insulation and ductwork, which the in-home evaluation covers.

How often should an HVAC system be serviced?

Twice a year covers most homes: once before cooling season, once before heating season. In a city like Brentwood, where housing stock spans several decades and system age can vary widely even between neighboring properties, staying consistent with that schedule helps catch problems before they become breakdowns. Documented HVAC maintenance also satisfies most manufacturer warranty requirements.

Is financing available for HVAC work in Brentwood?

Yes. Qualifying projects can be financed. During our in-home evaluation, we can also review Spire rebates, applicable federal tax credits, and any current seasonal offers.
