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If you experience uneven temperatures, excessive dust buildup, or rising energy costs, your ductwork may be damaged or outdated.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.

    Performed blower motor replacement and provided a complimentary blower wheel cleaning per (Heather). After completing the repairs, I tested system operation and verified proper cooling performance, with a temperature split of 19°F. The blower motor amperage is within the acceptable range. During the inspection, I noticed that the return air grille appeared clean from the outside but was restricted by dust buildup on the backside. I removed the accumulated dust from the back of the grille, rinsed the front grille, and reinstalled it. This restriction could contribute to increased static pressure, especially when the air handler closet door is closed, potentially placing additional strain on the blower motor and contributing to premature motor failure. At this time, the system is cooling and operating properly.

    Performed a diagnostic on the downstairs 1.5-ton Lennox unit and found the blower motor not operating. I tested the blower motor using a motor tester and determined that the motor may be damaged. The air filter is brand new, and upon inspection, I found the blower wheel heavily compacted with debris. I recommended blower wheel cleaning to the property management. I contacted the property management, and Zach approved ordering the replacement blower motor. The motor is covered under the manufacturer’s warranty; however, labor is not covered. The unit is temporarily down until the replacement motor can be installed. We are scheduled to return tomorrow to replace the blower motor, although the exact arrival time has not yet been determined. Current Status: Unit temporarily down pending blower motor replacement.

    Performed a diagnostic and found an error code on the thermostat indicating a drain line clog. Upon inspection, the system drain line was extremely clogged, and the drain pan had black mildew buildup. I informed the customer of the findings and provided a quote for drain line cleaning. The customer approved the repair. The customer mentioned that she is currently selling the house, so she does not want to enroll in a maintenance agreement at this time. I cleaned and cleared the drain line and applied Viper treatment to the drain system. I also replaced the system air filter at the customer’s request. After completing the service, I tested the system operation and verified that the drain line is flowing properly. The system is running and draining properly at this time.

    Performed a diagnostic on a Ducane air conditioning system located in the attic. Found the flow switch tripped due to a severely clogged primary drain line. Quoted the customer for drain cleaning, and the customer approved the repair. Due to the severe blockage, I cut out the existing drain trap, which was heavily clogged and in poor condition, and remade the trap. I ran a drain snake through the primary drain line until it cleared completely. After clearing the blockage, I flushed approximately six gallons of hot water through the drain line until the water was flowing clear. I also applied drain salt to help treat the line. Reassembled the drain system and treated the drain pan and primary drain line with Viper treatment. Reset the flow switch and tested the system in full cooling mode. The unit is cooling and draining properly at this time. Customer was completely satisfied with the completed work.

    Performed a diagnostic on the downstairs left unit#2. Upon arrival, the thermostat had no display. I checked the system voltage and found 120 volts on each leg, with 240 volts across the system. I checked the low-voltage fuse and found it blown. Further troubleshooting to determine the cause of the blown fuse found the contactor shorted, measuring approximately 0.94 ohms. I explained the findings and recommended replacing the contactor and low-voltage fuse. The customer approved the repairs. I replaced the contactor and fuse, then tested the system operation. After repairs, I checked system pressures, subcooling, superheat, temperature split, and overall operation. The system is now running and draining properly at this time.

    Performed a diagnostic on a 2.5-ton Carrier system and found the drain line clogged. I presented the customer with an option for drain cleaning and also explained the Arctic Membership. The customer accepted the Arctic Membership, and I completed the summer tune-up. I cleaned the drain system using a drain snake and flushed approximately six gallons of hot water through the drain line. I vacuumed the secondary drain pan and cleaned the primary drain pan and drain line. I also added Viper treatment to the drain system. After cleaning, I checked the system temperature split and replaced the air filter. The customer provided a new filter, which I installed and dated. During the inspection, I found the evaporator coil heavily compacted with debris and badly corroded. The customer is aware that the system is old and mentioned that he may sell the apartment. I also checked access to the roof. Security advised that the roof hatch is completely closed and they do not have a key to open it.

    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. I could not be happier with the service provided and highly recommend this company. The communication from the time I booked the appointment until after the job was completed was top notch.
