Westerville HVAC Company handles heating and cooling repair, service, installation, and replacement for homes and commercial properties across Westerville and Franklin County. Whether the furnace stopped working at midnight or the AC is blowing warm air on the hottest day of the year, we take those calls seriously.
Reach us every day from 5:30 AM to 11:00 PM at (380) 288-9789.
We check the furnace. We check the AC. We leave it running right. Emergency no-heat and no-cool calls are answered within those hours, and the fault gets scoped before anything is scheduled. Call and we'll get your heat or AC back on.
HVAC work like this is the bulk of what a season brings, and the calls tend to follow a pattern. The AC blows warm air when the refrigerant level drops or the condenser coil is fouled. The furnace blows cold when the igniter fails or the heat exchanger trips a safety. The heat pump runs but barely keeps up when the reversing valve sticks or refrigerant charge is off. The thermostat stops responding when wiring corrodes or the control board faults out.
When the technician who comes out runs a diagnostic, the job is to find the actual cause, not the nearest replacement part. That means checking airflow, testing the blower motor and air handler, and tracing a refrigerant leak before quoting a repair. The reason for a fault is explained, not just the fix, so you understand what failed and why before you decide anything. We'll get the fault identified and the work priced.
From aging systems to brand-new installs, replacement work covers the full range: central AC installation, furnace installation, heat pump installation, and ductless mini-split systems for spaces that don't have existing ductwork. When a system has reached the end of its useful life, a full replacement often makes more sense than continuing to repair it, and we can walk through both options on the call.
Every installation job comes with a written scope so you know exactly what the work covers before anyone shows up. The price is confirmed before the visit is scheduled, not after the equipment is already on the truck. If you've already been quoted a replacement by another company and want a second opinion, that is a normal request and we welcome it. Let us handle the install and the permits.
Every home's heating and cooling setup tells a different story, and so does every commercial property. For residential customers, that means seasonal tune-ups, thermostat and smart-control installation, ductwork repair and sealing, indoor air quality and air filtration, and whole-home humidifier or dehumidifier installation. For commercial customers and property managers, it means keeping heating and cooling running across rental units, office buildings, and multi-tenant spaces where a system failure affects more than one person.
Component-level work falls under the same umbrella: condenser and compressor service, evaporator coil cleaning, air handler repair, and duct sealing for systems that are losing conditioned air before it reaches the room. Nobody books a visit before you know what it covers. The scope and the price are settled on the call, so you can decide whether to schedule before committing to anything. We'll get the fault identified and the work priced.
If you've never hired an HVAC company before, a seasonal tune-up is the most straightforward place to start. A standard maintenance visit covers airflow checks, coil condition, refrigerant level, thermostat calibration, and blower motor inspection. The goal is to find a small problem before it becomes a no-heat call in January or a no-cool call in the middle of a July heat stretch in central Ohio.
A fault caught during a scheduled tune-up costs a fraction of what an emergency call costs, and the system runs more efficiently heading into the season it has to work hardest. We're available every day from 5:30 AM to 11:00 PM, so scheduling around a work day or a property visit is straightforward. Call in the morning. Ask what it involves. Decide in your own time.
Getting your comfort back is easier than you think, even when the situation feels urgent. Two calls make up most of the emergency volume: no heat in winter and no cool in summer. A furnace that stops working in January in Ohio is not a wait-until-Monday problem. Neither is an AC that quits during a humid August stretch when the overnight low stays above 70 degrees.
We take those calls every day from 5:30 AM to 11:00 PM. When you call, the fault gets scoped on the phone and a price is given before anything is booked. Emergency no-heat and no-cool calls are treated as the priority they are. We'll get the fault identified and the work priced.
Franklin County runs through all four seasons with real force. Cold winters put sustained load on heating equipment, and hot, humid summers load both the cooling system and the moisture levels inside the home. The services below come up regularly here because the climate calls for them.
Ohio winters test heating equipment hard. A furnace that struggles to hold temperature in January, runs constantly without reaching setpoint, or trips the heat exchanger safety repeatedly is signaling that another repair may not be the answer. Full system replacement means removing the old equipment, installing a matched heating and cooling setup, and confirming the new system performs before the job is closed out. Every replacement comes with a written scope so the work is defined before it starts, and the price is confirmed before the visit is scheduled.
A heat pump handles both heating and cooling from a single outdoor unit, which suits Westerville's four-season climate well. Rather than generating heat by burning fuel, a heat pump moves heat from outside air into the home in winter and reverses the process in summer. Installation involves setting the outdoor unit, connecting the air handler, running refrigerant lines, and pairing the system with a compatible thermostat. How a heat pump performs during a hard Ohio cold snap is worth a direct conversation on the call, since supplemental heat and system sizing both factor into the answer.
Franklin County summers are humid, and excess indoor moisture creates problems that a standard AC cannot fully address on its own. Air that holds too much moisture feels warmer than the thermostat reads, and condensation on surfaces and window frames is a sign the system is working harder than it should. A whole-home dehumidifier installs in line with the HVAC system and pulls moisture from the air in every room, not just the space where a portable unit sits. The counterpart in winter is a whole-home humidifier: Ohio heating seasons dry indoor air significantly, and low humidity affects comfort as well as wood floors, trim, and furniture.
Getting your comfort back is easier than you think, and it starts with a phone call. When you call, the job gets scoped on the phone and a price is given before anything is booked. If a diagnostic visit is needed, the fee for that visit is explained before you confirm it. There is no point in sending someone out before you know what the call covers.
What affects the final cost varies by job. A repair on a single component costs differently from a full system replacement. System size, equipment brand, and the scope of ductwork involved all factor in. Second opinions on replacement quotes are welcomed. If you have a quote in hand and want to compare, call and we can work through what it covers. We'll get the fault identified and the work priced.

A furnace nearing the end of its useful life tends to show a pattern of symptoms rather than a single fault: short cycling, where the system kicks on and off without completing a full heat cycle, is one of the most common. Uneven heat distribution, a heat exchanger that trips a safety repeatedly, or a system that runs continuously without reaching the set temperature all point in the same direction. Any of those symptoms is worth a diagnostic call before the system fails completely on a cold night in January.
Warm air from the vents when the thermostat is set to cool is the most common sign, and it usually points to a refrigerant issue or a fouled condenser coil. Ice forming on the outdoor unit or the evaporator coil, short cycling, or a system that runs continuously without dropping the indoor temperature are all diagnostic indicators. Water pooling near the air handler is another sign, typically from a clogged condensate drain or a coil that has frozen and thawed.
Cold air from a furnace that is running usually means the heat exchanger has tripped a safety, the igniter has failed, or the flame sensor is too dirty to hold the burner on. Short cycling, where the furnace fires and then shuts off before completing a full heat cycle, can come from an overheating limit switch, a blocked flue, or a dirty filter restricting airflow. Both symptoms get traced to the actual cause on the diagnostic visit rather than addressed with a parts swap.
A frozen evaporator coil blocks airflow through the air handler, which means conditioned air cannot reach the supply registers even when the compressor is running. The symptom is warm air from the vents combined with reduced airflow, sometimes with ice visible on the refrigerant lines near the air handler. The underlying cause is usually low refrigerant charge, a dirty coil, or a failing blower motor, and the diagnostic visit identifies which one applies.
If the furnace is out in winter, close off unused rooms and use any available supplemental heat to keep pipes from freezing. If the AC is out in summer, close blinds on sun-facing windows to reduce heat gain and move to the coolest part of the home. Do not attempt to reset the system repeatedly if it is tripping a safety, as that can mask the fault and make the diagnostic harder.
Clear access to the furnace, air handler, and outdoor unit before the visit. That means moving storage away from the equipment in the utility room or basement, making sure the outdoor condenser is accessible, and locating the thermostat so the technician can test the system through a full cycle. If there is a filter access panel that is difficult to reach, knowing where it is ahead of time speeds up the diagnostic.
The diagnostic starts with what the system is doing and what it is not doing, based on what was described on the call. The person who comes out checks the full system, not just the most obvious component, before quoting a repair. That means testing the blower, the controls, the refrigerant circuit, and the heat exchanger or coil depending on the equipment, so the quote reflects what the system actually needs.
The age of the system changes the answer, and that gets said on the call. A system that is still within its useful life and has a single, isolated fault is usually worth repairing. A system that has been repaired repeatedly or is old enough that parts availability is becoming a problem is a replacement conversation. A heat pump installation makes sense when the goal is consolidating heating and cooling into one system, and the call is the right place to work through what that involves for your specific setup.
A straightforward diagnostic and repair, like a capacitor replacement or a thermostat swap, can be completed in under two hours. A more involved repair, like a blower motor replacement or a refrigerant recharge with leak detection, takes longer depending on what the diagnostic turns up. Full system installation and replacement is a multi-hour job and gets scoped in advance so you know what the timeline looks like before the visit is booked.
The system gets tested through a full cycle before the visit is closed out, so you can confirm the fault is resolved and the equipment is performing correctly. The technician walks through what was done and what was found, so you understand the repair before anyone leaves. If the diagnostic turned up a secondary issue that was not part of the original scope, that gets noted and you can decide whether to address it on the same visit or schedule a follow-up.
The system runs through a complete cycle with the technician present, which means the heating or cooling output gets verified at the supply registers and the controls are tested for correct operation. On installation jobs, the new equipment is commissioned and checked against the written scope before the visit is closed out. Any issues that come up during the final check get addressed before the technician leaves the property.
A system that is losing efficiency, whether from a dirty coil, low refrigerant charge, a failing blower motor, or a heat exchanger that is not transferring heat correctly, runs longer to reach the set temperature. Longer run times mean higher energy use, and the increase shows up on the bill before the system fails completely. A diagnostic visit that catches the underlying fault usually costs less than several months of inflated energy bills.
A repair that addresses the symptom without finding the cause puts the system back into service with the underlying fault still present. That means the same symptom returns, often at a worse time and with more damage to surrounding components. A proper diagnostic takes longer on the front end and costs more than a parts swap, but it produces a repair that actually holds.
Older homes in Westerville often have original ductwork that has developed leaks or disconnected sections over decades of use, which shows up as uneven temperatures from room to room or one side of the house that never reaches the set temperature. Dated equipment running at reduced efficiency struggles more during the coldest and hottest weeks of the year. A diagnostic visit can identify whether the problem is in the equipment, the duct system, or both, and the repair or replacement recommendation follows from what the inspection actually finds.

How often should a heating or cooling system be tuned up?
Once a year is the standard starting point for most systems. A furnace or heat pump benefits from a check before the heating season, and the cooling side benefits from a check before summer. If the system is older or has had repeated faults, two visits a year gives you a better picture of where it is headed. The call is the right place to talk through what makes sense for your specific equipment and how it has been running.
How do ductwork leaks raise energy bills?
When supply ducts leak, conditioned air escapes into unconditioned spaces like attics, crawlspaces, or wall cavities before it reaches the room. The system has to run longer to compensate, which drives up energy use without improving comfort. Return duct leaks pull unconditioned air into the system, which makes the equipment work harder to heat or cool it. Sealing those leaks reduces run time and brings the energy use back in line with what the system was designed to deliver.
What does a thermostat or smart-control upgrade actually involve?
The existing thermostat is removed and the wiring is checked for compatibility with the new control. Smart thermostats require a common wire in many installations, and not every older system has one wired in, so that gets confirmed before anything is ordered. The new thermostat is wired, configured, and tested through a full heating and cooling cycle before the visit is closed out. If the system is a heat pump with auxiliary heat, compatibility is a more involved check and gets addressed directly on the call.
Diagnosis Explained Before Any Repair
When the technician who comes out identifies the fault, the reason for it gets explained before a repair is quoted. You understand what failed and why before you decide anything.
What are signs of a refrigerant or airflow problem?
Warm air from the vents when the system is set to cool is the most common sign of a refrigerant issue. Ice forming on the refrigerant lines or the outdoor unit, a system that runs continuously without dropping the indoor temperature, and reduced airflow from the supply registers all point in the same direction. Airflow problems often show up as one side of the home that stays warmer or cooler than the rest, or as a blower that sounds like it is working harder than it used to. Both types of fault get traced to the actual cause on the diagnostic visit.
What can strange noises from the unit mean?
A grinding or scraping sound from the air handler usually points to a blower motor bearing that is wearing out. A banging or clanking sound from the outdoor unit can indicate a loose component in the compressor or a failing fan blade. A high-pitched squealing sound often comes from a belt-drive blower on older equipment. Clicking that continues past startup can point to a faulty relay or control board. None of these should be ignored, because a fault that starts as a noise tends to progress to a complete failure if the underlying cause is not identified.
How does a dirty filter or coil hurt system performance?
A clogged filter restricts airflow through the air handler, which reduces how much conditioned air reaches the supply registers and forces the blower to work harder. Over time, restricted airflow causes the evaporator coil to freeze, which blocks airflow further and can damage the compressor if the system keeps running. A dirty condenser coil on the outdoor unit reduces the system's ability to release heat, which makes the compressor run hotter and longer than it should. Both problems show up as reduced cooling or heating capacity and higher energy use before they cause a component failure.
Emergency No-Heat and No-Cool Calls Handled
We take no-heat and no-cool calls every day from 5:30 AM to 11:00 PM. The fault gets scoped on the phone and a price is given before the visit is booked.
Do I need to be home for the HVAC work?
For a diagnostic visit or a repair, someone needs to be present to provide access to the equipment and to confirm the fault is resolved before the technician leaves. For installation work, someone needs to be available for the duration of the job since the scope gets walked through at the start and the finished system gets tested at the end. If you are coordinating access for a tenant or a rental property, that is a normal situation and the details get worked out on the call when the visit is scheduled.
How do estimates and pricing work for HVAC jobs?
The job gets scoped on the phone before anything is booked. For repair calls, a diagnostic fee covers the visit and the fault identification, and that fee is explained before you confirm the visit. The repair price follows from what the diagnostic finds, and you decide whether to proceed before any work starts. For installation and replacement jobs, a written scope is provided so the work is defined and the price is confirmed before the visit is scheduled. If you have questions about what a specific job covers, the call is the right place to ask.
Older Systems and New Installs Both Covered
Whether the job is a repair on a system that has been running for years or a full installation on new construction, we handle both and scope the work the same way before anything starts.
When does it make more sense to repair an older system than to replace it?
A system that is still within its useful life and has a single, isolated fault is usually worth repairing. A system that has needed multiple repairs in a short period, is old enough that parts are becoming difficult to source, or is running at significantly reduced efficiency is a replacement conversation. The age of the system changes the answer, and that gets said directly on the call rather than pushed toward one option or the other. If you already have a replacement quote and want to compare, that is a normal request and we work through what it covers.
What causes a system to short-cycle?
Short cycling, where the system fires up and shuts off before completing a full heating or cooling cycle, usually points to one of a few causes. On the heating side, an overheating limit switch, a blocked flue, or a dirty filter restricting airflow are the most common. On the cooling side, low refrigerant charge, a frozen evaporator coil, or an oversized system that cools the space too quickly before humidity is addressed all produce the same symptom. The diagnostic visit traces the actual cause rather than addressing the symptom with a reset.
How is indoor air quality improved through the HVAC system?
The most direct approach is upgrading the filtration on the existing air handler, either with a higher-efficiency filter media or a dedicated air filtration system that installs in line with the ductwork. A whole-home air purifier works the same way, treating air as it passes through the system rather than in a single room. For humidity, a whole-home dehumidifier handles excess moisture in summer and a whole-home humidifier replaces moisture lost to winter heating. All of these work through the existing duct system, so the improvement covers every room the system serves.
