When a heat pump stops heating or an AC stops cooling in the middle of a Lake County summer, the call comes in fast. That is the most common reason someone in Clermont reaches out, and it is the job we are set up to handle. We cover the full range of heating-and-cooling work for homes and properties across this city: AC repair and service, heat pump repair and installation, ductwork repair and sealing, thermostat and smart-control upgrades, indoor air quality, whole-home dehumidification, and full system replacement when the equipment has reached the end of its useful life.
Clermont has a mix of newer construction and older homes where the original equipment has been running hard for years. Some of those systems are overdue for a tune-up or a closer look at the ductwork. Others are candidates for a high-efficiency replacement that would make a real difference over a long cooling season. Whatever the situation, we scope the job on the phone before anything is scheduled.
Call (321) 241-3235 to get started.
Most HVAC calls come down to a gap between what the system is set to do and what it is actually delivering. The section below covers the specific situations that account for the majority of the work we do in Clermont and the surrounding area.
A system that starts, runs for a minute or two, and then shuts off before the house reaches temperature is short cycling. It puts stress on the compressor, raises energy costs, and leaves the space uncomfortable. The cause is usually an oversized unit, a refrigerant problem, a dirty evaporator coil, or a control fault. A diagnostic visit works through each of those possibilities before any repair is recommended.
Banging or clanking from the outdoor unit points toward a loose or broken component inside the compressor or a failing fan blade. A squealing sound from the air handler usually means a worn blower motor bearing. Rattling can be loose sheet metal in the duct system or debris that has made its way into the outdoor unit. Any of these is worth diagnosing before the fault develops into something more expensive.
Heat pumps are the dominant heating-and-cooling system across this region, and they handle both seasons in one unit. When a heat pump is not heating, is blowing air that barely differs from room temperature, or has stopped switching modes, the reversing valve, refrigerant charge, or defrost controls are the likely starting points. We diagnose and repair heat pump faults and handle replacement when the system has reached the point where repair is no longer the practical answer.
For the smaller share of Clermont properties with gas heating equipment, a system that starts and then shuts down, or that will not ignite at all, often traces back to a dirty or failing flame sensor or an ignition control issue. These faults are worth addressing promptly, because a system that fails to ignite reliably tends to get worse rather than better with use.
A thermostat that is not reading the room temperature correctly, or that has lost communication with the air handler, can make a perfectly functional system behave as though something is wrong. Upgrading to a programmable or smart control improves comfort and can reduce how hard the system works across a long cooling season. Compatibility with heat pumps and multi-stage systems is checked before any control is recommended.
Conditioned air that escapes into an attic before it reaches the living space is wasted energy and a direct cause of rooms that will not cool down. Duct sealing closes those gaps. Where sections of ductwork are damaged or have deteriorated over time, we replace what needs replacing. Airflow testing and uneven-temperature troubleshooting are part of the same diagnostic visit.
Before calling for a service visit, a few checks are worth doing. They will not fix every fault, but they account for a meaningful share of calls that turn out to be something simple.
Check the thermostat first. Confirm it is set to the correct mode, that the temperature is set where you expect, and that the display is responding. A thermostat that has lost its settings after a power interruption, or that has a dead battery, can stop the system from running at all.
Check the filter next. A filter that has not been changed in several months can restrict airflow enough to cause the evaporator coil to freeze, which stops cooling entirely and can eventually damage the blower motor. A clogged filter is one of the more common causes of a system that runs but does not cool the space down.
Check that the supply switch at the air handler is in the on position, and that the breaker serving the outdoor unit has not tripped. A tripped breaker that resets and trips again is a sign of a fault that needs a diagnostic visit. One that stays on after a single reset may be a temporary interruption. If the system still does not perform correctly after these checks, that is the point to call.
Duct problems are one of the more common reasons a home in this area has persistent comfort issues that a straightforward repair does not fix. In homes with attic air handlers, ducts run through spaces that reach extreme temperatures in summer. Joints that were not properly sealed at installation, or that have separated over time, allow conditioned air to escape before it reaches the registers.
The result is a system that runs longer than it should, energy bills that do not match how the house feels, and rooms at the end of the duct run that stay warmer than the rest of the house. Duct sealing and repair address the distribution problem directly. In some cases, the issue is not leakage but undersized duct runs that restrict airflow regardless of how well they are sealed.
Humidity, sun exposure and insulation all change how a system should be sized. A duct system that was adequate for the original equipment may not support a replacement unit that moves air differently. We check duct condition and airflow as part of any system replacement, not as an afterthought. Take a look at the page covering our heating and cooling services to see what else is covered.
The price for a repair call depends on what the diagnostic finds. The fault itself, the parts involved, and what it takes to reach the component all affect the final figure. A compressor that is accessible from the top of the outdoor unit is a different job from one that requires pulling the unit apart. A refrigerant charge that needs a leak traced before it is refilled takes longer than one that does not.
For a replacement or new installation, the quote is based on a load calculation for the specific property. Square footage, ceiling height, window area, insulation, and duct condition all factor into what size equipment the space actually needs. A unit that is oversized for the home will short cycle and leave humidity behind. One that is undersized will run continuously without reaching temperature.
The rate is confirmed on the call before anything is scheduled. If the diagnostic uncovers a fault that changes the scope of the work, that is discussed before anything additional is carried out. We'll go through what the service covers before it is booked.
A price agreed before each visit. Clear scheduling each visit. Code-compliant every time.
Scheduling a service call starts on the phone. We are open every day from 8:00 AM to 8:00 PM, including weekends. When you call, someone who knows the trade answers, talks through what the system is doing, and confirms what the visit will cover and what it costs before anything is booked.
For emergency calls where a property has no cooling at all, we work to get a visit arranged as quickly as the schedule allows. A home without air conditioning in this region is not a comfortable place to wait, and we treat those calls accordingly.
For rental properties and commercial spaces where the system has to keep running, we work around what the situation requires. A tenant who needs to be present, a business that cannot close for a half-day, or a property where access has to be coordinated in advance are all situations we handle on the call. The more detail you can share when you book, the more smoothly the visit goes.
It helps to know the brand and approximate age of the equipment, what the system is doing or not doing, and whether the problem is with heating or cooling. If the system has had recent service, that is worth mentioning. The more the person on the phone understands about the situation, the more focused the visit will be.
Call us and we'll walk you through your options.

The housing mix across this part of Lake County covers newer subdivisions built in the last decade and older homes where the equipment has been running for fifteen or more years. Duct systems in older properties often reflect additions and modifications that the original layout never accounted for. Knowing what is common in this area shapes how a diagnostic visit goes and what the options look like.
It is the first thing worth checking, because a blocked filter is one of the most common causes of reduced airflow, a system that runs without cooling, and a unit that freezes up. If the filter is clogged, replace it and give the system a few minutes to recover before deciding whether to call.
Keep the filter clean and replace it on a regular schedule. Keep the area around the outdoor unit clear of vegetation and debris. Make sure supply and return vents inside the home are not blocked by furniture or drapes. These steps do not replace a maintenance visit, but they reduce the load on the system between professional service calls.
The answer depends on equipment availability and the current schedule. For a planned replacement where the existing system is still functional, calling ahead gives us time to confirm equipment and coordinate the visit properly. For a system that has failed entirely, we work through what is available as quickly as the schedule allows.
Call (321) 241-3235 and we will tell you what the timeline looks like.
Closing vents is generally not recommended and can work against the system. A central HVAC system is designed to move a specific volume of air through the duct system, and closing vents creates back pressure that can reduce airflow, cause the system to work harder, and in some cases lead to duct leaks. If certain rooms are consistently uncomfortable, the duct system or zoning is usually the better place to look.
Replacing only one half of a matched system is generally not recommended. The outdoor unit and the air handler are designed to work together, and mismatching them can reduce efficiency, affect refrigerant charge, and put the equipment manufacturer's coverage at risk. We go through the options on the call and explain what a full replacement versus a partial replacement involves.
Newer construction in this area tends to have equipment that is still within its serviceable life, though duct sealing and thermostat upgrades come up regularly. Older homes are more likely to have equipment approaching or past the point where repair costs start to approach replacement costs, and duct systems that have never been properly sealed or that were modified during additions without adjusting the airflow. The diagnostic visit accounts for both, and the options are explained before any work is scheduled.
High humidity puts more demand on the cooling system because the equipment is removing moisture from the air as well as lowering the temperature. A system that is working harder than it should, or that is not sized correctly for the humidity load, tends to develop faults sooner and run less efficiently over time. Keeping up with seasonal maintenance, particularly coil cleaning and drain line clearing, reduces the effect of that additional load on the equipment.
A tune-up is a scheduled maintenance visit that covers the coil, drain line, refrigerant level, electrical connections, blower, and thermostat calibration on a system that is functioning normally. A diagnostic visit is a targeted investigation of a specific fault or symptom. Both start with the technician working through the system, but the purpose and the scope are different.
A system that has been underperforming for a season or two, a room that has never cooled down properly, or equipment that keeps running without quite doing the job is not a situation that improves on its own. The diagnostic is where it starts. From there, the repair or replacement path becomes clear, and the work gets done.

Every heating and cooling job we handle in Clermont starts with a diagnosis, not a guess. The table below lays out what each service covers, who it fits best, and one practical detail worth knowing before you call. Use it to get oriented, then call us and we will scope the job on the phone before anything is booked.
| Service Type | What the Service Includes | Best For | Things to Know |
|---|---|---|---|
| Heat Pump Repair & Service | Refrigerant pressure and leak check, Reversing valve function test, Heating and cooling mode verification, Blower and air handler inspection | Any home or rental property with a heat pump that is not reaching set temperature | A heat pump that works in cooling but not heating often has a reversing valve fault, not a refrigerant problem. |
| High-Efficiency Central AC Replacement | Load calculation and equipment selection, R-22 system retirement and replacement, New unit installation and commissioning, Airflow and refrigerant verification after startup | Homeowners with a system over fifteen years old or one still running on R-22 refrigerant | R-22 refrigerant is no longer manufactured. Recharging a leaking R-22 system is expensive and temporary. Replacement is usually the more practical path. |
| Full System Installation & Replacement | Load calculation and equipment sizing, Removal of existing equipment, New system installation and commissioning, Thermostat compatibility and wiring check | Homeowners replacing an aging system, an R-22 unit, or equipment with repeated failures | Proper sizing matters more than brand. An oversized unit in Florida short-cycles and leaves humidity behind. |
