Frequently Asked Questions

Here are some commonly asked questions about our range of HVAC services in Kissimmee.

If your air conditioner isn’t cooling as it should, is making odd noises, or has an unexplained increase in energy usage, it may need servicing. You might also notice weak airflow, unpleasant smells, or the system cycling on and off too frequently. Addressing these issues early can help prevent bigger, more expensive problems down the road.

Furnaces can develop problems like ignition failure, malfunctioning thermostats, and clogged filters that restrict airflow. If your system is making loud or unusual noises, struggling to maintain a consistent temperature, or shutting off unexpectedly, it likely needs repair. Regular maintenance can help detect these problems early and keep your furnace running efficiently.

If your water heater takes longer to heat water, produces inconsistent temperatures, or has visible rust or leaks, it may be time for a replacement. Tanks that are over 10 to 15 years old often lose efficiency and may require more frequent repairs. Upgrading to a new unit can provide better performance, improve energy savings, and ensure a steady hot water supply.

Ductless air conditioners provide targeted cooling, allowing you to set different temperatures in individual rooms, which can improve comfort and efficiency. They don’t require ductwork, making installation easier and reducing energy loss associated with traditional HVAC systems. Additionally, they operate quietly and help improve air quality by reducing dust and allergens.

Choosing the right pool heater depends on factors like your pool’s size, local climate, and energy efficiency goals. Gas heaters warm water quickly and are great for colder areas, while heat pumps and solar heaters are more energy-efficient but may take longer to heat the pool. Understanding your usage habits and budget will help you determine the best system for your needs.

If you experience uneven temperatures, excessive dust buildup, or rising energy costs, your ductwork may be damaged or outdated. Leaks, poor insulation, or improper sizing can cause your HVAC system to work harder than necessary, leading to inefficiency. Replacing old ducts can improve airflow, enhance indoor comfort, and help reduce utility costs.

Air filtration systems help reduce indoor air pollutants such as dust, pet dander, and pollen, improving overall air quality. High-efficiency filters, like HEPA filters, can capture microscopic particles that trigger allergies and respiratory issues. Installing an air filtration system can also help extend the life of your HVAC unit by keeping dust and debris from clogging components.

Indoor air quality testing can identify pollutants like mold, carbon monoxide, and volatile organic compounds that can impact your health. Poor air quality may contribute to allergy symptoms, respiratory problems, and long-term health issues. Testing allows you to find and address specific contaminants, whether through air purifiers, dehumidifiers, or upgraded filtration systems.

Heat pumps provide both heating and cooling by transferring heat instead of generating it, making them more energy-efficient than conventional systems. They work best in moderate climates but can still function in colder areas with additional heating support. Because they use less electricity, heat pumps can lower energy costs while maintaining comfortable indoor temperatures year-round.

    Service call - 2017 Carrier - leaking thru ceiling - verified issue, water coming through ceiling from return. Drain completely clogged and float not functioning properly. Guests were set to arrive in less than hour, so had to make quick drain service. Snaked/flushed drain until flowing and cleaned as much water from return/platform as possible. Found float switch wired incorrectly, separated the wires correctly and float now working as designed. System now cooling and draining without issue. Unable to look over full system due to guests arriving, owner very happy we were able to come out and fix so fast

    Upon arrival, the customer had already vacuumed the condensate drain line, and the drain was clear. However, the thermostat had no power. During the inspection, I found that the customer had disconnected the safety float switch wiring and removed the entire float assembly. I reinstalled the safety float switch assembly and properly reconnected the wiring. Once everything was restored to its correct position, power was restored to the thermostat and the system started operating again. The safety float switch was empty and dry, confirming that the customer had already cleared the drain blockage. I offered the customer a maintenance agreement and explained the available membership options. The customer requested time to review the options and call back regarding enrollment. I proceeded with the first preventive maintenance visit today. Performed the following services: Cleaned the condensate drain line using a drain snake. Applied Viper drain treatment.

    Performed the first Polar preventive maintenance visit on the Carrier 2.5-ton system. The air handler is located inside the first-floor bathroom closet, and the outdoor condenser is located on the right side at the rear of the building. The system’s drain line is the one closest to the unit. This property has one main drain serving all three floors. Performed drain line cleaning, cleaned the drain pan, applied Viper treatment, and flushed the drain line with six gallons of hot water to ensure proper drainage. Checked system operating pressures, subcooling, superheat, temperature split, compressor amperage, outdoor fan motor amperage, and indoor blower motor amperage. During the inspection, I found bacterial growth inside the air handler cabinet. I also found the outdoor contactor badly pitted and the condenser fan capacitor slightly out of the manufacturer’s specified tolerance.

    Performed a diagnostic and found the condensate drain line clogged and the drain pan full of algae buildup. The customer has an active maintenance agreement. Performed a complete drain line cleaning by running the drain snake from outside to inside and inside to outside to remove the blockage. Cleaned the drain pan and applied Viper treatment to both the drain line and drain pan to help prevent future algae buildup. After completing the cleaning, I tested the system in cooling mode and checked the temperature split. The unit is cooling properly and draining correctly at this time. System operation is normal.

    Performed a Comfort Performance maintenance visit and completed a full system inspection. Upon inspecting the air handler, I found bacterial growth on the wiring and portions of the insulation inside the cabinet. The existing UV light is not operational. I recommended replacing the UV light to help prevent further bacterial growth inside the air handler cabinet and on the evaporator coil. Inspected the air filter and found it clean. The evaporator coil was also clean, with only a few localized areas of bacterial growth. The drain pan was slightly dirty, so I cleaned the pan and drain line and applied Viper treatment. Inspected the outdoor condenser and found the contactor slightly pitted. I recommended replacing the contactor as preventive maintenance. The capacitor tested within the manufacturer’s specifications. Checked system refrigerant pressures, cooling superheat, and temperature split. All operating readings were satisfactory, and the system is cooling properly at this time.

    Performed a diagnostic on the Rheem pool heat pump due to an H2 sensor failure error code. I checked the error code and performed multiple system inspections. I tested the sensor and confirmed it was reading properly. I also tested the pressure switch and verified that it was operating correctly. I continued troubleshooting by inspecting the water filter, which appeared clean. During the inspection of the pool area, I discovered a plastic cup obstructing water flow inside the skimmer basket. I removed the obstruction and coordinated with property management to restart the heat pump. After restoring operation, I checked the refrigerant pressures, measured the temperature split across the evaporator coil, and verified the temperature difference between the pool water inlet and outlet. The system started and operated properly, with all checked operating conditions appearing normal. Final Status: The pool heat pump is running and heating properly at this time.

    Performed a diagnostic on a 20-year-old Goodman system. Upon inspection, I found the system completely out of refrigerant and observed a significant amount of oil inside the condenser, indicating a potential refrigerant leak. I provided the customer with a quote for leak detection and one pound of refrigerant. I clearly explained that this service was intended to locate the leak and was not a repair or a permanent solution to restore the system to normal operation. Due to the age of the equipment and the condition of the system, the customer requested a proposal for a new system. I contacted the office to create a call for Kenneth to assist with the replacement proposal. Kenneth arrived at the job site, presented the proposal, and the customer signed the agreement for a new system installation. The system will remain out of operation until tomorrow, when the new equipment is scheduled to be installed. Diagnostic Fee: Waived. No diagnostic fee was charged because the customer procee

    Victor was our technician and provided excellent service. He was prompt with arriving at the time we requested. I was expecting the worst but was pleasantly surprised with the cost of the repair. Victor was honest and wasn’t trying to sell me something I didn’t want. He made several recommendations on a service plan.
