Florida in summer gives you no margin for error with air conditioning. When outdoor temperatures hit 95°F with 80% humidity, an HVAC system running at 70% capacity isn’t enough to keep a home livable.
This isn’t abstract technical information. It’s the difference between a comfortable vacation and one where the entire group is sweating inside the house at 3 PM on day three.
At Top Stay properties, HVAC system maintenance is one of the protocols Home Vacation manages most rigorously. Here’s why and how.
Most residential homes and vacation villas in Orlando have central HVAC systems that manage the temperature of the entire house from one or two main units.
A typical system for a 4-6 bedroom villa includes an outdoor unit (the condenser, the part you see outside the house with the large fan) and an indoor unit (the air handler, generally in the garage or a utility closet), connected by refrigerant lines and distribution ductwork.
The system works by removing heat from the indoor air, transferring it outside, and recirculating the cooled air. In the process, it also dehumidifies the air, which in Florida is nearly as important as cooling it.
Vacation villas have a different usage pattern than a primary residence. They can sit empty for several days and then have 10-12 people using them simultaneously for a week.
That usage pattern has implications for the AC system:
During high occupancy, the system works harder than normal. More people generate more body heat, open and close doors more frequently, and use the kitchen and laundry more. A well-maintained system handles this without problems. One with dirty filters or low refrigerant can fail under that load.
During vacancy, the system is typically set to maintain a baseline temperature (usually 78-80°F) that prevents humidity damage and allows the house to reach a comfortable temperature quickly when new guests arrive.
HVAC filters capture dust, allergens, and particles from the air. When they become saturated, airflow drops, the system works harder to achieve the same result, and indoor air quality falls.
In Florida, where dust and seasonal allergens are more abundant than in dry climates, filters need to be changed more frequently than the standard recommendation for temperate climates.
Home Vacation changes filters in all Top Stay properties every 30 days during peak season (June-August) and every 60 days the rest of the year.
The evaporator coils (indoor) and condenser coils (outdoor) accumulate dirt over time. A condenser with dirty coils can’t dissipate heat efficiently, causing the system to work harder and consume more energy without better results.
In the Orlando area, outdoor condensers also accumulate leaves, pine seeds, and in communities with heavy vegetation, moss that can grow in Florida’s humidity.
Coil cleaning is a job for a certified technician. Home Vacation schedules it twice yearly for all properties: before peak summer season and before the winter-spring season.
Refrigerant is the fluid that makes heat transfer possible in the system. If there’s a leak (leaks are more common than you might think in systems with several years of use), the level drops and the system’s cooling capacity drops with it.
A system with low refrigerant doesn’t cool adequately, runs in longer cycles, and can eventually damage the compressor, which is the most expensive component in the system.
Refrigerant verification requires specialized equipment and a certified technician. Home Vacation performs this check annually as part of the general system review.
The air distribution ducts run through the attic, which in Florida can reach temperatures of 140°F in summer. If ducts have leaks or insulation has deteriorated, some of the cooled air is lost before it reaches the rooms.
This makes the system work harder and makes some rooms in the house harder to cool than others. Duct inspection isn’t a routine monthly task, but it’s part of the periodic reviews Home Vacation performs on properties with systems older than 5 years.
FlipWise has installed smart thermostats like Nest or Ecobee in most renovated properties in the Top Stay portfolio. These thermostats have two key advantages for managing a vacation villa:
Remote control: Home Vacation can adjust the property’s temperature remotely, setting the house to a comfortable temperature when guests are scheduled to arrive, without anyone being physically present.
Usage reports: Smart thermostats generate data about system behavior. If the time it takes to reach the target temperature increases significantly, that can indicate a maintenance issue before the guest reports it as a failure.
First, check the thermostat. The target temperature must be below the current room temperature for the system to run. In Florida, setting the thermostat to 72-74°F (22-23°C) is the standard comfortable range.
If the system is running but the house isn’t cooling down:
In the unlikely event of a complete system failure during a stay, Home Vacation’s protocol includes an HVAC technician within 4 hours and, if the repair takes longer, compensation or guest relocation.
This is the logic guiding Home Vacation’s investment in preventive maintenance:
A filter change costs $15-$30 in materials and 15 minutes of work.
A coil cleaning costs $150-$250 per technician visit.
A compressor replacement costs $1,500-$3,000 in parts and labor.
A system failure during a guest’s stay carries an additional cost: compensation, possible relocation, and the impact on the review. A negative review mentioning “the AC didn’t work” can cost more in future rates than any repair.
Preventive maintenance isn’t an expense. It’s protection of the property’s income.
What temperature should I set the thermostat to?
For comfort in Florida, between 72°F and 76°F is the most common range. Below 70°F may prevent the system from dehumidifying properly.
Is it normal for the system to run almost continuously in summer?
Yes, on hot days the system may run in longer and more frequent cycles. What isn’t normal is running continuously without reaching the target temperature.
Can I control the AC in my room independently?
Depends on the system. Some villas have independent zones. Others have a central system with one thermostat. Verify when booking if this is important for your group.
What do I do if one room isn’t cooling well?
Check that the vent in that room is open. If the problem persists, report it to Home Vacation for inspection.
