Homes in Mount Dora range from older properties with original duct systems and equipment that has run for decades to newer construction where the hardware is more current but the humidity load is just as demanding. A town this size generates a particular kind of HVAC work: systems that have not been serviced in years, additions where the ductwork never quite reached the far room, and equipment that keeps getting repaired when replacement would be the more practical answer. We handle all of it, for homeowners, for landlords managing a few rentals, and for small commercial properties where a system failure affects tenants or customers directly.
Whether the call is about a unit that stopped cooling overnight or a property owner planning a full replacement before summer peaks, the process starts the same way. Someone who knows the trade answers the phone, scopes the job, and confirms the price before anything is scheduled. We are open every day from 8:00 AM to 8:00 PM.

The housing stock here leans toward single-family homes, and a meaningful share of them are sitting on equipment that is well past the age where efficiency and reliability start to diverge. Heat pumps handle both heating and cooling for most properties in this part of Lake County, and when one of them develops a fault, the whole house loses comfort in both directions. Older homes often have duct systems that were installed before current sizing standards, and those ducts are working harder than they should to move air through rooms that were added or modified over the years.
For smaller commercial properties in town, the stakes are different. A retail space or office that loses cooling in July cannot stay open comfortably, and the repair-versus-replacement question carries a cost-of-downtime element that a homeowner's situation does not. We work across both, and the diagnostic process is the same either way: find the actual fault before quoting anything.
This is one of the most common calls in this region, and the cause is rarely obvious from the outside. A unit that runs continuously but cannot bring the temperature down is usually dealing with a refrigerant issue, a coil problem, or an airflow restriction somewhere between the air handler and the registers. In a climate where the AC runs for most of the year, those faults develop gradually and then become noticeable all at once on the first genuinely hot day.
These are the electrical components that tell the compressor and fan motors when to run and how hard to work. A failing capacitor is one of the more common single-component failures on an AC system, and it often shows up as a unit that hums but will not start, or one that starts slowly and then trips the breaker. A contactor that is worn or pitted causes similar symptoms. Control board faults are less common but harder to diagnose without working through the rest of the system first.
A system that runs without cycling off is either undersized for the space, working against a duct leak that is dumping conditioned air somewhere it cannot do any good, or fighting a refrigerant charge that is off. In humid conditions, a system that never cycles properly also fails to remove moisture from the air the way it should, which makes the space feel warmer than the thermostat reading suggests.
A burning smell on startup usually points to dust burning off a heat element that has not run in months, but it can also indicate an electrical fault in the blower motor or control board. A musty smell is almost always a moisture problem, either standing water in the drain pan, a blocked condensate line, or mold growth on the evaporator coil. Both are worth investigating before the system runs another season.
In this region, the more common need is dehumidification rather than humidification. A whole-home dehumidifier works independently of the cooling cycle, pulling moisture from the air on mild days when the AC does not run long enough to manage humidity on its own. For properties where indoor air quality is a persistent concern, it is one of the more practical upgrades available.
The price for any job comes from the diagnosis, not from a general range. A repair call covers the visit and the diagnostic, and the quote for the repair itself is given after the fault is identified. For a replacement or installation, the quote follows a load calculation and accounts for what the job actually involves: the equipment, the access, and whether the existing ductwork can support the new system or needs attention first.
What moves a quote in one direction or another is the nature of the fault, what has to be reached to fix it, and whether a repair makes sense relative to the age and condition of the equipment. A system still running on R-22 refrigerant, for example, faces a different repair calculation than a system on current refrigerant. We go through those factors on the call and confirm the price before anything is scheduled.
A price agreed before each visit. Clear scheduling each visit. Code-compliant every time.
A ductless mini-split is the right answer in a number of situations that come up regularly in older homes and smaller commercial properties. A room addition that was built without connecting to the existing duct system, a converted garage, a detached workspace, or a historic property where running new ductwork through the walls would be destructive or impractical: all of these are candidates for a dedicated ductless unit.
A multi-zone mini-split installation lets different rooms or spaces run at different temperatures independently, which matters when a home has occupants with different comfort needs or when a commercial property has spaces with very different heat loads. Each indoor unit is controlled separately, so one zone running does not require all of them to run. We handle both single-zone and multi-zone ductless systems, from selecting the right capacity to completing the installation.
An older thermostat that is not reading room temperature accurately, or one that cannot communicate properly with a modern heat pump, can make a well-functioning system behave erratically. Short cycling, failure to reach the set temperature, and inconsistent fan behavior are all symptoms that sometimes trace back to the control rather than the equipment. Replacing the thermostat resolves them without touching the system at all.
A programmable or smart thermostat gives better control over run cycles and can reduce how hard the system works during the long cooling season. For heat pumps, compatibility matters: not every smart thermostat is wired for a heat pump's reversing valve, and we confirm the wiring before recommending a control. The job is straightforward when it is set up correctly, and it is worth doing once rather than twice.
Uneven temperatures across a home are almost always a duct or airflow problem. The most common causes are a duct run that is undersized for the room it serves, a leak somewhere in the distribution system that is bleeding conditioned air into the attic or a wall cavity, or a damper that has failed in a closed position. Humidity, sun exposure and insulation all change how a system should be sized, and a room with a large south-facing window and poor insulation puts a different demand on the duct serving it than the rest of the house does.
A diagnostic visit for uneven temperatures works through airflow at each register, checks duct condition where it is accessible, and identifies where the distribution system is falling short. The fix might be sealing a duct leak, resizing a run, or in some cases adjusting the equipment itself. We confirm what the visit covers before it is booked. More of the detail sits on our services page.
When a system stops working entirely, whether there is no cooling in July or no heat on a cold January night, the call gets handled the same way as any other: the situation is scoped on the phone, the price is confirmed, and the visit is arranged. For rental properties and commercial spaces where the occupants cannot simply wait, we work through what the schedule allows and confirm availability on the call.
Appointments are confirmed before the visit. The technician who comes out arrives knowing what the likely fault is, based on what was discussed on the phone. Seasonal maintenance visits are worth booking before the peak of summer rather than during it, when demand is highest and scheduling takes longer. For a pre-season tune-up, the coil, drain line, refrigerant charge, and electrical connections are all checked before the system is under full load.
From a quick tune-up to a whole-system replacement, the diagnosis comes first. We are open every day from 8:00 AM to 8:00 PM. Call us and we'll walk you through your options.
We serve Mount Dora and the surrounding communities across Lake County, including Tangerine, Eustis, Sorrento, Mount Plymouth, and Zellwood.

We handle the full range of heating-and-cooling work, and the job is understood before anyone is scheduled.
A sharp rise in running cost without a change in usage usually means the system is working harder than it should to reach the set temperature. Common causes include a refrigerant loss, a dirty coil, a duct leak that is sending conditioned air somewhere it is not supposed to go, or a failing component that is drawing more power than normal. A diagnostic visit works through each of those possibilities.
Yes. When a property has to remain occupied or operational during the visit, we work through the access and timing on the call before anything is scheduled. The technician who comes out arrives knowing the constraints, and the scope of the visit is confirmed in advance so the work can be carried out with as little disruption as possible.
Older homes in this area often have duct systems that were sized and installed under different standards, and the equipment in them may not have been serviced regularly. That combination tends to produce airflow and uneven-temperature problems alongside the equipment faults themselves. When we scope a job in an older home, the duct condition is part of the diagnostic, not an afterthought.
In this region, a central air conditioner removes moisture as a byproduct of cooling, but it is not designed to manage humidity independently. On mild days when the AC does not run long or often, indoor humidity can stay high enough to cause discomfort and encourage mold growth. A whole-home dehumidifier operates on its own schedule and keeps humidity in check regardless of whether the cooling is running. For properties where clammy air or musty odors are a recurring issue, it addresses the root cause rather than the symptom.
A maintenance visit after a repair makes sense if the system has not had a full service recently. A repair addresses the specific fault, but a maintenance visit covers the coil, the drain line, the electrical connections, the blower, and the refrigerant charge as a whole. If those have not been looked at in a while, combining them is a practical approach.
The sooner a fault is diagnosed, the less it tends to cost. A capacitor that is failing does not announce itself far in advance, and a clogged drain line becomes a water-damage problem quickly in a Florida summer.
