Sometimes the problem is one part: a component that wore out while the rest of the system has years left in it. Other times the whole unit has run its course and the honest answer is a replacement. Seward Heating and Cooling Systems handles both ends of that call for homes and businesses in St. Matthews. Whether a technician is swapping a faulty control board or pulling out an aging furnace-and-AC pair and starting fresh, the work is handled by qualified HVAC technicians who know what they are looking at.
St. Matthews is a small city where the housing stock runs the full range: compact older homes, larger renovated properties, and commercial spaces that each have their own setup and their own demands. Property managers and business owners call us alongside homeowners, and the work varies accordingly. Same-day service is available, and you get a price on the phone before anything is scheduled.
Not every heating and cooling call looks the same, and the work that comes out of a place this size reflects that variety. Some calls are about a system that stopped working. Others are about a system that is working but not well. And some are about equipment that has simply reached the end of what it can reasonably do.
A furnace that will not ignite, an air conditioner that runs but blows warm air, a heat pump that has lost its ability to hold temperature on either end: these are the calls that need a fast response. The diagnostic visit identifies the fault, whether that is a refrigerant leak, a failed component, or an airflow problem the system has been fighting for a while. You get a clear explanation of what was found before any repair begins.
Uneven temperatures, a unit that runs constantly without satisfying the thermostat, or a space that never quite reaches comfort on the worst days of the season: these symptoms are worth taking seriously. They often point to something that can be corrected, whether that is an evaporator coil that needs cleaning, a duct that is leaking conditioned air into the wrong space, or a thermostat that is not communicating accurately with the equipment. Zoning and comfort-control systems come up in this conversation too, especially in homes where one area is consistently harder to manage than the rest.
Full system replacement is a different kind of call. When a furnace or central AC unit has been repaired multiple times and efficiency has dropped, the better investment is often a new system sized and installed correctly for the home. The service page carries the full breakdown of what replacement involves and what the scope typically looks like. Call us and we'll walk you through your options.
The sooner you call, the sooner your comfort is back, but some problems turn out to be something simple. Before picking up the phone, it is worth running through a few things that resolve a surprising number of calls.
Check the thermostat first. Confirm it is set to the right mode and that the temperature setting is actually where you think it is. A thermostat that was bumped, drained its batteries, or lost its programming can make a perfectly functional system appear broken. Smart controls and programmable thermostats occasionally lose their settings after a power interruption, and restoring them takes less than a minute.
Check the filter. A filter that has not been changed in several months can restrict airflow enough to cause the system to overheat and shut down, or to run without moving enough air to satisfy the thermostat. Pull it out and hold it to the light. If you cannot see through it, that is the place to start.
Check the supply switch and the circuit. HVAC systems have a dedicated supply switch, often mounted near the unit and easy to mistake for a light switch. If it was turned off accidentally, the system will not respond. A tripped breaker is worth checking as well, though if the breaker trips again immediately after being reset, stop there and call us rather than resetting it a second time.
Every job has a few things that move the number: what the fault actually turns out to be, how accessible the equipment is, and whether a repair makes sense or whether replacement is the better answer. Those are the things that shape a quote, and none of them can be settled before a technician has seen the system.
When you call, we explain the rate on the phone based on what you have described. The diagnostic visit confirms the scope, and you get a clear price for the repair or the replacement before any work begins. If the diagnosis changes what the job involves, that gets explained before anything proceeds. The HVAC work done properly, start to finish, means no work starts until you have agreed to what it covers.
What would change a quote from the initial estimate: a fault that turns out to be deeper in the system than the symptoms suggested, equipment that needs additional components to bring it up to current standards, or a situation where repair and replacement are genuinely close in cost and the better path needs a real conversation. We walk through that with you. Call us and we'll walk you through your options.
Annual maintenance is the most reliable way to catch a problem before it becomes a breakdown. A pre-season check on the AC in spring and a furnace inspection in fall cover the components most likely to fail under load: ignition systems, heat exchangers, refrigerant charge, coil condition, and airflow. For property managers overseeing multiple units in St. Matthews, scheduled maintenance across a portfolio is something we can plan around your calendar.
A system that runs for long stretches without bringing the space to temperature is not just uncomfortable. It is a sign that something is working against the equipment: a refrigerant problem, a coil that has not been cleaned, a duct that is losing conditioned air before it reaches the room, or a system that was never quite sized right for the space. Refrigerant leak diagnosis and evaporator coil cleaning and repair are part of how we work through this kind of call.
When the furnace and AC are both aging and one of them fails, replacing the pair together often makes more practical sense than repairing one and leaving the other on borrowed time. Full HVAC system replacement means the new equipment is matched, installed to code, and tested before the technician leaves. Heat pump installation is part of this conversation too. The regional climate sits in the transition zone where heat pumps handle both heating and cooling efficiently, and a growing number of St. Matthews homeowners are making that switch when the old system reaches the end of its life.
These are among the most common component failures in residential HVAC equipment. A capacitor that has failed will prevent a motor from starting. A worn contactor interrupts the electrical signal that tells the compressor or fan to run. A control board fault can produce symptoms that look like something larger. Each of these is a repair, not a replacement, when the rest of the system is in reasonable shape. The diagnostic visit tells us which it is.
Homes in St. Matthews that were built or renovated before central air was standard sometimes run on window units or have a heating system with no cooling side at all. Central air installation adds a full cooling system tied to the existing ductwork, or we assess whether the duct layout supports it and what the right path forward looks like if it does not. Call for a quote and we will explain what the installation involves for your specific home.
Whole-home air filtration, air purifiers, and humidity control systems all connect to the existing HVAC equipment and address what the heating and cooling system alone does not handle. In this part of Kentucky, whole-home dehumidification is one of the most practical upgrades a homeowner can make. Humid summer air that a central AC cannot fully wring out makes the space feel warmer than the thermostat reads and can create ongoing air quality problems. We install whole-home dehumidifiers as part of the broader indoor air quality work we do alongside the heating and cooling equipment.
Same-day service. Upfront pricing. Qualified technicians.
Booking an HVAC service call is simple. Call during our hours, describe what the system is doing, and we give you a rate on the phone. Same-day service is available for both repair and emergency calls in St. Matthews. We take no-heat and no-cool calls every day from 8:00 AM to 8:00 PM.
The technician who works on your home runs this area every week. For tenants in a rental property, we work around occupancy so the space does not have to be vacated. For a business that has to stay open, we plan the visit to minimize disruption. You get a call before the technician arrives, and the system is tested before the visit ends.
Affordable rates. Flexible timing. Reliable comfort.
We serve St. Matthews and the nearby communities of Richlawn, Norbourne Estates, Beechwood Village, Woodlawn Park, and Bellewood. The broader Jefferson County area is covered as well. If you are not sure whether your address falls within our service area, call us and we will confirm. Most calls in this part of Jefferson County are within our regular coverage.
If the scope is still open, the HVAC details page is the place to start.
Start with the basics: confirm the thermostat is set to the right mode and temperature, check that the circuit breaker for the HVAC equipment has not tripped, and make sure the filter is not completely blocked. If those are all fine and the system still is not responding, that is the right point to call (502) 826-9787 and get a technician out for a proper diagnostic.
It affects the conversation but not the process. The technician diagnoses the fault the same way regardless of age. On older equipment, we will give you an honest read on whether the repair makes sense relative to the system's remaining useful life, so you can make an informed decision before committing to the work.
It does, and it shows up in a specific way. A central air conditioner removes heat and some moisture from the air, but in a genuinely humid summer it often cannot keep indoor humidity at a comfortable level on its own. The system ends up running longer to maintain temperature while the space still feels clammy. A whole-home dehumidifier connected to the existing HVAC equipment addresses the moisture side of the problem directly, and we install those alongside the heating and cooling work we do throughout the area.
We can assess the situation and determine what is needed to complete the work correctly. Call (502) 826-9787 and describe what has been done so far. We will let you know whether we can step in and what finishing the installation would involve.
Someone with access to the property and the equipment needs to be available for the visit. That can be the tenant, the landlord, or a property manager. We work with whoever is on site. If you manage multiple rental properties and want to coordinate access for several addresses, call us and we will work through the scheduling with you.
Yes. Newer equipment benefits from regular maintenance just as older equipment does. Catching small issues early, keeping the coil and components clean, and confirming refrigerant levels are correct helps newer systems perform as designed and extends their working life. Skipping maintenance because the equipment is new is one of the more common ways problems develop before they should.
We plan visits around occupancy and work to minimize disruption for tenants who need to stay in the space. When you call, let us know it is a rental and we will confirm the appointment window with you so you can coordinate with the tenant. The technician arrives within the confirmed window, and the system is tested before the visit ends. For landlords managing multiple properties, we can plan maintenance visits across a portfolio rather than handling each one as a separate emergency.
When the appointment is confirmed, we will tell you what to expect about timing. We do not promise a specific arrival time, but we aim to give you enough information to plan your day. If you have specific constraints around availability, mention them when you call and we will do our best to work around them.
If your system has stopped working, or you are not sure whether a repair or a full replacement is the right answer, the place to start is a phone call. Seward Heating and Cooling Systems gives you a rate before anything is scheduled and a clear price before anything is replaced.
Call (502) 826-9787 and we will get started.

We handle the full range of heating and cooling work for homes and businesses in St. Matthews and across Jefferson County. The table below breaks down each service, what it covers, and who it fits best. If you have questions about a specific job or want to know what a service would cost for your situation, call us and we will walk you through your options.
| Service | What It Covers | When You Need It | Good to Know |
|---|---|---|---|
| Furnace & AC System Replacement |
| St. Matthews homeowners with older systems that have declined in efficiency or been repaired multiple times | St. Matthews's older housing stock means many systems are at or past their practical service life. Replacement is often the more cost-effective path when repair costs have been adding up. |
| Seasonal Maintenance & Tune-Ups |
| Any homeowner, landlord, or property manager who wants to reduce the likelihood of a mid-season breakdown | Two visits per year, one in spring and one in fall, cover both systems before each peak season and catch small issues before they become repairs. |
| Ductwork Repair & Sealing |
| Homes with uneven temperatures room to room or rising energy bills without an obvious cause | Leaking ducts lose conditioned air into attics and crawl spaces before it reaches the living area. Sealing them improves comfort and reduces equipment wear. |
| Emergency HVAC Service |
| Any situation where the heating or cooling system has stopped working and the home is becoming uncomfortable or unsafe | Emergency calls are accepted every day from 8:00 AM to 8:00 PM. Same-day service is often available depending on the schedule. |
| Indoor Air Quality & Air Filtration |
| Households dealing with dust, allergens, or humidity discomfort that a standard filter does not address | Jefferson County's humid summers make air quality upgrades especially practical. A filtration system works alongside the existing HVAC equipment. |
| Full System Installation & Replacement |
| Homeowners replacing an aging or repeatedly repaired furnace and AC combination | A correctly sized system uses less energy and holds temperature more evenly. Sizing is confirmed before any equipment is ordered. |
| Heat Pump Repair & Service |
| Homes with a heat pump that is struggling in either heating or cooling season | Jefferson County's climate is well suited to heat pumps. A system that loses efficiency in mild weather often has a fixable refrigerant or airflow issue. |
| Whole-Home Dehumidification & Humidity Control |
| St. Matthews homeowners whose home feels warmer than the thermostat reads or who have noticed moisture or air quality issues in summer | A central AC system is not always designed to fully manage Jefferson County's summer humidity on its own. A whole-home dehumidifier maintains consistent indoor humidity regardless of outdoor conditions. |
| AC Repair & Service |
| Homeowners or property managers with an AC that stopped cooling or is running inefficiently | Kentucky summers put heavy demand on cooling equipment. Calling early in the season avoids the busiest repair windows. |
| Thermostat & Smart-Control Installation |
| Homeowners who want better control over comfort and energy use, or whose existing thermostat is no longer reading correctly | A smart thermostat that reduces runtime during unoccupied hours can meaningfully lower the seasonal load on heating and cooling equipment. |
| Heat Pump Installation |
| Homeowners replacing both a furnace and AC with a single system, or adding cooling to a space that currently only has heating | Modern heat pumps handle temperatures well below freezing, making them a practical year-round solution for Jefferson County's climate rather than just a warm-weather option. |
| Heating & Furnace Repair |
| Any home or rental property that has lost heat or is producing inconsistent warmth | Fall is the best time to catch a developing furnace problem before cold weather turns it into an emergency call. |
