Jeffersonville is a city with a real mix of property types: older homes on established streets, newer construction closer to the commercial corridors, and a range of small businesses and multi-unit buildings that each carry their own equipment. The housing stock here spans decades, which means the systems inside it span decades too. Some properties are running original equipment that has held on well past its expected life. Others have been partially updated, with a newer furnace paired to an aging coil, or a replacement AC connected to ductwork that was never properly sized. Seward Heating and Cooling Systems handles all of it, residential and commercial, repair and replacement, routine and urgent.
Landlords managing rentals, business owners keeping a commercial space comfortable, and homeowners dealing with a system that stopped working on a bad day all call for different reasons, but the process is the same. You get a rate on the phone before anything is scheduled, and a qualified HVAC technician handles the work. Same-day service is available, and we take calls every day from 8:00 AM to 8:00 PM.
Sizing a replacement system to match what was there before is a starting point, not an answer. A unit that ran the property for fifteen years was sized for conditions that may have changed. Additions, finished basements, new windows, and even changes in how the space is used all affect what the load calculation comes out to. Putting in the same tonnage as the old system skips that step.
An oversized system short-cycles, which means it reaches temperature quickly, shuts off, and never runs long enough to pull humidity out of the air. An undersized system runs constantly and still cannot keep up on the hardest days. Neither one performs the way a correctly sized system does. When we scope a full HVAC system replacement, the equipment recommendation follows the property, not the label on the old unit.
Energy-efficiency upgrades are a natural part of that conversation. A new system installed correctly and sized properly uses less energy to hold a comfortable temperature than an aging unit running at reduced capacity ever could.
This region's summers bring persistent humidity that a central air conditioner manages only partially. A whole-home dehumidifier connects to the existing HVAC system and maintains a consistent indoor humidity level regardless of what the air outside is doing. Whole-home humidifiers address the other side of the problem in winter, when forced-air heating dries the air out. Both are installed as part of the HVAC system, not as standalone appliances.
A dirty evaporator coil is one of the more common reasons an AC system loses cooling capacity without any obvious mechanical failure. The coil sits inside the air handler and picks up dust and debris over time, which insulates it and reduces heat transfer. Cleaning restores performance. Where the coil itself is damaged or leaking refrigerant, repair or replacement is the path forward, and we handle both.
A grinding, banging, rattling, or squealing sound from a furnace, air handler, or outdoor unit is the system telling you something has changed. It is not always a failure in progress, but it is always worth diagnosing before it becomes one. Blower motor bearings, loose panels, debris in the outdoor unit, and failing capacitors are among the common causes. We identify the source and explain what the fix involves before any work begins.
Ductless mini-split systems solve a specific problem: a space that needs heating and cooling but has no practical way to connect to central ductwork. Additions, detached garages, older homes where running new duct is not feasible, and commercial spaces with isolated zones are all good candidates. Installation involves mounting the indoor head unit, placing the outdoor compressor, and running the refrigerant lines between them. No ductwork is required.
A thermostat that reads temperature incorrectly, fails to communicate with the system, or simply lacks the programming options a property needs is worth replacing. A smart thermostat upgrade gives better scheduling control and can reduce energy use when the space is unoccupied. We confirm compatibility with the existing system before installation and test the connection before we leave.
This part of the region sits in the transition zone where heat pump performance is strong enough to handle both heating and cooling through most of the year. A heat pump installation replaces separate heating and cooling equipment with a single system. For properties already on a heat pump that has reached the end of its service life, replacement follows the same process: load calculation, equipment selection, and installation by qualified HVAC technicians. Call us and we'll walk you through your options.
The sooner you call, the sooner your comfort is back, and that is especially true when there is no heating or no cooling in a property at all. Same-day service is available for Jeffersonville and the surrounding area. Emergency calls are handled the same way as scheduled ones: you get a rate on the phone, a technician comes to the property, and the work is explained before it starts.
For tenants in a rental, the process works the same way. For a business that has to stay open, we work around the hours that matter. The technician who works on your home runs this area every week, which means the response is practical rather than theoretical.
If a property has no heat in winter or no cooling in summer, do not wait to see if the system comes back on its own. Call (502) 826-9787 and we will confirm what is available on the schedule.
The rate is explained on the phone before anything is scheduled. What moves a quote is what the fault turns out to be, what has to be reached to get at it, and whether a repair or a replacement is the better answer once the system is in front of a technician.
A repair on a straightforward fault is a different conversation from a full HVAC system replacement. A system that is accessible and easy to diagnose is a different conversation from one buried in a crawl space or a commercial ceiling. We do not start work until you have agreed to the price.
For a replacement, the quote covers the equipment and the installation. If the ductwork needs attention as part of the job, that is identified during the assessment and included in the scope before anything is confirmed. Call us and we'll walk you through your options.
A repair call starts with a symptom: no cooling, no heat, a system that runs but does not hold temperature, or something that sounds wrong. The technician diagnoses the fault, explains what was found, and gives you a price before any repair begins. The HVAC work done properly, start to finish, means the fix addresses the actual fault rather than the nearest accessible component.
A system that is running does not always mean a system that is running well. Annual maintenance catches small problems before they become failures. A spring AC tune-up and a fall furnace inspection are the two visits that matter most in a four-season climate. We check refrigerant levels, inspect the heat exchanger, test ignition and safety controls, and confirm airflow is where it should be. Code-compliant HVAC work on every job applies to maintenance visits as much as it does to repairs and installations.
When a system has been repaired repeatedly and efficiency has dropped to the point where running it costs more than replacing it, the replacement conversation is the right one. We scope the job, confirm the right equipment for the property, and handle the installation. The service page carries the full breakdown of what each type of replacement involves. Give us a call and we'll get the comfort back.
Filtration, humidity control, and air quality are not separate from heating and cooling. They are part of what the system does, or fails to do, depending on how it is set up. A whole-home air filtration system works with the existing air handler to reduce airborne particles throughout the property. A whole-home humidifier or dehumidifier ties into the same system and maintains moisture levels that a thermostat alone cannot address.
For Jeffersonville properties dealing with humid summers, a dehumidifier installation is one of the more practical improvements a homeowner or property manager can make. High indoor humidity makes a space feel warmer than the thermostat reads and creates conditions that affect air quality over time. Whole-home humidity control handles the problem at the source rather than room by room.
We install and service air purifiers, filtration upgrades, and humidity control equipment as part of the broader HVAC scope. Pick up the phone and we'll handle the system.
We serve Jeffersonville and the surrounding area throughout Clark County, including Utica, Glenview, Clarksville, Indian Hills, and Riverwood. Residential and commercial calls are covered across the area. If you are not sure whether your address falls within our service area, call us and we will confirm.
Affordable rates. Flexible timing. Reliable comfort.
Homeowners in Jeffersonville often read the system service rundown before getting in touch.
It does, and it shapes the assessment before anything else. Older homes often have ductwork that was never sized for modern equipment, and putting a new system on undersized ducts limits what the equipment can do. Newer construction tends to be tighter and better insulated, which changes the load calculation. We assess the property before recommending equipment, not after.
Call (502) 826-9787 and give us your address. We will confirm whether the location falls within the area we cover. Properties in unincorporated areas or on town boundaries are handled the same way as any other address. If we cover it, we will schedule the visit.
A spike in heating or cooling costs without a change in how the system is being used often points to a loss of efficiency somewhere in the system. Common causes include a dirty coil, refrigerant loss, duct leaks, or a component that is working harder than it should because something else has failed. A diagnostic visit is the right way to find out which one applies to your system.
Yes. We work on heating and cooling equipment regardless of who installed it. The make, model, and installation history do not affect whether we can service the system. If you have documentation on the equipment, it is useful to have on hand, but it is not required to book a call.
Yes. A thermostat upgrade does not have to be tied to a larger repair or installation. If your current control is not reading temperatures accurately, not communicating with the system reliably, or simply too old to program effectively, a standalone thermostat installation is a straightforward job that can make a real difference in how the system performs.
We do. Commercial buildings, rental properties, and multi-unit residential calls are all part of what we handle across Jeffersonville and Clark County. Property managers and business owners call for the same reasons homeowners do, and the process works the same way: a rate on the phone, a qualified technician on site, and work explained before it starts. Call (502) 826-9787 and we will confirm availability.
We take calls every day from 8:00 AM to 8:00 PM, including weekends. If the system goes down outside those hours, the safest step is to use supplemental heat or move to the coolest part of the home, avoid repeatedly resetting the system, and call us as soon as we open. Same-day service is often available for the first available slot, and we will confirm what is on the schedule when you call.
A repair that fails quickly usually means the root cause was not fully addressed, a replacement part was not the right fit, or there is an underlying issue that the first repair did not account for. When we diagnose a system that has been worked on recently, we look at what was done and what the system is doing now to determine what actually needs to be fixed.
Filter replacement is something most homeowners can handle on their own, and we are happy to walk you through it on the phone. Thermostat adjustments that involve reprogramming or replacing the control typically require a technician on site. If you are not sure whether a problem can be resolved without a visit, call (502) 826-9787 and we will help you figure out the right next step.
If the initial diagnostic does not turn up a clear cause, the technician explains what was checked and what the next steps are. Some faults are intermittent and harder to catch in a single visit. We keep working through the likely causes until the problem is identified and resolved.
When a property in Jeffersonville has no heating or no cooling, the window for waiting is short.

We handle the full range of heating and cooling work for homes and businesses in Jeffersonville and across Clark 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 |
| Jeffersonville homeowners with older systems that have declined in efficiency or been repaired multiple times | Jeffersonville'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 | Clark 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 | Clark 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 |
| Jeffersonville 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 Clark 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 Clark 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. |
