When the furnace goes out or the air conditioner stops keeping up, you want a straight answer about what the system needs and what it will cost to fix it. When you call us, someone who knows the trade picks up, listens to what the system is doing, and scopes the job on the phone. You get the rate for the visit and a clear picture of what the call covers before anything is put on the calendar. That is where every job starts.
We handle the full range of residential and commercial heating and cooling work in London and across Madison County. Repair, maintenance, installation, and full system replacement are all part of what we do. We are available every day from 9:00 AM to 11:00 PM, including weekends.
Whether the heat went out overnight or the AC has been struggling for a week, call (380) 979-9289 and we will get it on the schedule.
A town London's size carries a lot of housing stock that has been around for a while. Systems that have been running for many years without a tune-up, ductwork that was sized for a floor plan that has since been changed, and thermostats that have never been upgraded are all common starting points for a call. None of that makes a job harder to scope. It does mean the diagnostic has to account for more than just the symptom in front of us.
Older equipment often shows wear in ways that are easy to miss if you are not looking for them. A furnace that still fires but takes longer to reach the set temperature, or an air conditioner that cools the main floor but leaves the upstairs warm, can point to issues with the heat exchanger, the blower, the refrigerant charge, or the duct system. We check all of those before any repair is quoted.
Properties in the outlying areas around London, including homes in Deer Creek Township, Somerford Township, and Choctaw Lake, sometimes have equipment configurations that differ from a straightforward residential install. A detached garage with its own mini-split, a basement unit serving an addition that was never properly tied into the main duct run, or a heat pump that was installed without adequate airflow planning are all situations we see. The visit covers what is actually there, not what a standard install would look like.
When you call, the scheduling conversation happens on the same call as the diagnostic scope. We confirm what the visit covers, give you the rate, and find a time that works for your property. For no-heat and no-cool calls, emergency service is taken seriously and handled as a priority. If the furnace is out in the middle of a cold stretch or the AC has stopped running during a heat wave, that is not a situation to leave on hold.
For rental properties and homes with tenants, we work around the occupant's schedule. The visit does not require the property owner to be present if the tenant can provide access, and the scope and pricing are confirmed before anyone comes out so there are no decisions that have to be made on the spot.
A commercial property that cannot close for the day needs a different approach to scheduling. We talk through what the system is doing, what the space requires, and what can be handled in a window that does not interrupt operations. That conversation happens on the call, not after a site visit that leads to a second appointment.
Pricing for any HVAC job is shaped by what the system turns out to need once it has been assessed. A diagnostic visit establishes the starting point. From there, the cost depends on what the fault turns out to be, what has to be accessed to reach it, and whether a repair is the right answer or whether replacement makes more practical sense.
A refrigerant leak paired with a worn compressor is a different conversation from a failed capacitor on an otherwise sound unit. A duct system that has lost significant airflow through leaks at the joints adds to the scope of a replacement job. Those variables are explained after the diagnostic, before any work is authorized.
You get the rate for the visit when you call. You get the repair or replacement price after the system has been assessed and before anything is scheduled. Nothing moves forward until the cost is agreed. You get answers on the call, not after a callback.
The visit starts with a look at what the system is doing in its current state. We do not power the equipment down before checking it, because a system that has been shut off loses diagnostic information that is often the clearest indicator of the root cause.
The person doing the work goes through the components most likely to cause the symptom: refrigerant charge and coil condition for a cooling problem, heat exchanger and igniter condition for a heating problem, and airflow and duct condition when the issue is uneven temperatures or a system that cannot keep up. Electrical connections on the unit, thermostat calibration, and blower performance are part of that check regardless of the presenting symptom.
Once the assessment is complete, the findings are explained before any repair is authorized. The cost for the repair is confirmed at that point, and the system is tested before the visit ends. If the diagnostic finds something that changes the scope, that is discussed before any additional work begins.
A retail space, a medical office, or any commercial property where comfort affects customers or operations has a different tolerance for a system failure than a private home. A furnace that stops working in January or an AC that fails during a busy summer week is not a problem that can wait for a standard appointment slot.
When you call about a commercial property in London, the scheduling conversation accounts for what the business needs. Work that can be staged across a quiet period, a weekend, or early morning hours before the space opens is something we discuss on the call. Some jobs can be completed in a single visit. Others, like a full system replacement or a ductwork overhaul, may need to be broken into phases. We talk through what the timeline looks like before anything is committed.
Seasonal maintenance scheduled before the peak heating or cooling season is the most reliable way to avoid an emergency call in the first place. A tune-up visit in the fall catches problems before the furnace is under full load, and a spring check covers the AC before the first hot stretch.
A system that has been repaired multiple times in a short stretch, runs longer and longer to reach the set temperature, or leaves parts of the home consistently uncomfortable is usually telling you that repair is no longer the right answer. A replacement assessment starts with a load calculation to make sure the new equipment is sized correctly for the space. An oversized unit short-cycles and leaves humidity problems behind. An undersized one runs constantly without satisfying the set point. Getting the sizing right matters as much as the equipment choice itself.
A banging, grinding, or rattling sound from a furnace or air conditioner usually means something mechanical is loose or failing. Running the system through that kind of noise turns a moderate repair into a larger one. A squealing sound from the blower motor, a clicking that does not stop after startup, or a rumbling from the outdoor unit all point to specific components. The diagnostic identifies which one before any parts are ordered.
When dust, allergens, or persistent odors are a problem in the home, the HVAC system is usually the right place to address it. A whole-home air filtration or purification system integrates with the existing equipment and treats the air across every room the system serves, not just in one space. Humidity control works the same way. A whole-home dehumidifier handles the moisture that a standard air conditioner leaves behind on humid summer days, and it does it across the whole house rather than one room at a time.
Leaking ductwork pushes conditioned air into wall cavities and attic spaces instead of into the rooms where it belongs. The result is a system that runs longer, uses more energy, and still leaves parts of the home uncomfortable. Airflow and uneven-temperature troubleshooting often leads back to the duct system, particularly in homes where additions were made without properly extending the original duct run. Sealing and repair addresses those losses at the source.
A system that turns on and shuts off before completing a full heating or cooling cycle is usually dealing with one of a few specific problems: an oversized unit that satisfies the thermostat too quickly, a refrigerant charge that is off, a dirty coil that is causing the system to trip on a safety limit, or a thermostat that is reading the temperature incorrectly. Short cycling puts extra wear on the compressor and the blower motor, so it is worth diagnosing before it leads to a larger failure. Smart thermostat installation sometimes resolves the issue when the control itself is the root cause.
We serve London and the communities around it across Madison County. That includes Union Township, Lafayette, Deer Creek Township, Choctaw Lake, and Somerford Township. Residential homes, rental properties, and commercial spaces throughout the area are all covered.
If you are not sure whether your address falls within our service area, call and ask. We will give you a straight answer on the phone. If you would rather read than call, the HVAC services page has the detail.
A system that moves air without conditioning it is usually experiencing a failure in the heating or cooling component rather than the air handler. For a furnace, that points to the burner, igniter, or heat exchanger. For an air conditioner, it points to the refrigerant circuit, the compressor, or the outdoor condenser. The air handler is doing its job, but the heat exchange is not happening.
Faults that appear only after the system has been running for a period, such as a component that overheats before failing or a refrigerant issue that only shows under load, are approached by running the system through a full cycle during the diagnostic visit. We note what conditions produce the symptom and work backward from there rather than making a guess based on a cold system.
Whether a previously installed part stays in place depends on whether it is compatible with the repair or the new equipment and whether it is in good condition. We assess what is already there during the diagnostic visit and explain the recommendation before any work is authorized.
When the existing ductwork is aging or was not properly sized for the current floor plan, a replacement assessment includes a look at the duct system alongside the equipment. If the ducts are leaking significantly or restricting airflow, addressing them as part of the replacement job produces better results than installing new equipment in a compromised system. The scope and cost of any duct work is explained before anything is authorized.
Ductwork problems are identified through a combination of airflow testing, visual inspection of accessible sections, and in some cases pressure testing. Rooms that are consistently the wrong temperature, high energy use relative to the set point, and visible gaps or disconnections at accessible joints are all starting points for the assessment.
Yes. If the diagnostic finds problems on both sides, or if a tune-up is scheduled to cover the full system before a season change, both are addressed in the same visit. The scope is confirmed on the call so the visit is planned for what the system actually needs rather than a single component.
Zoning systems that divide a home into independently controlled areas can be added to some existing setups, depending on the ductwork configuration and the equipment already in place. Whether it is practical for a specific property is something we assess on the call and confirm during a visit. Not every existing system is a good candidate, and we say so when it is not.
The diagnostic process is the same regardless of where the property sits. The visit covers the system, the symptom, and what the equipment needs. Properties in Deer Creek Township, Somerford Township, or Choctaw Lake are covered the same as a call from within London.
When the heat or the AC is not working, the answer is a phone call, not a form submission and a wait.
Call (380) 979-9289 and someone who knows the trade picks up, scopes the job, and gives you a price before anything is scheduled.
We are available every day from 9:00 AM to 11:00 PM. There is no callback queue to sit in before the system gets looked at.
Close by, we also take heating and cooling work in: West Jefferson, Lake Darby, Pleasant Township, Prairie Township, Galloway. See the whole of our coverage list.
Heating and cooling work covers a wide range of jobs, and knowing what each service involves helps you call with confidence. Below is a plain-language look at what we handle for homes and businesses in London and across Madison County. Every row reflects work we take on regularly, and every job starts the same way: a clear explanation of what the system needs before anything is authorized.
| Service | What It Covers | When You Need It | Helpful Details |
|---|---|---|---|
| Emergency HVAC Service |
| Any home or property where the heating or cooling system has stopped working entirely | We take emergency calls every day from 9:00 AM to 11:00 PM. A no-heat or no-cool call is not treated as a low-priority item. |
| Full System Installation & Replacement |
| Homeowners replacing aging or repeatedly failing equipment, or adding HVAC to a new space | Pairing a new furnace with a new AC unit at the same time is common in this area and often makes sense on both cost and efficiency grounds. |
| Seasonal Maintenance & Tune-Ups |
| Homeowners who want the system checked before peak heating or cooling season | Seasonal maintenance is scheduled around your calendar. Calling before the peak season means the system is ready before it is under full demand. |
