Frequently Asked Questions
Below, you’ll find some frequently asked questions about our range of services in Davenport.
Regular maintenance is key to keeping your AC running efficiently. We recommend scheduling a professional inspection at least once per year to catch potential issues early. This helps your system operate at peak performance, reduces energy consumption, and extends the unit’s lifespan.
Ductless air conditioning provides a flexible cooling solution, especially for homes without existing ductwork. These systems allow for customized temperature control in different rooms, improving energy efficiency and comfort. Their sleek design and quiet operation make them a popular alternative to traditional HVAC systems.
Maintaining good indoor air quality involves several steps. Keeping your HVAC system clean and replacing filters regularly can help reduce dust and allergens. Installing air purifiers or using UV air sanitizers can further eliminate airborne contaminants, creating a fresher and healthier environment.
Choosing the right furnace involves selecting a unit that matches your home’s heating needs. A properly sized and energy-efficient system will provide reliable warmth while keeping utility costs in check. Professional installation ensures safe operation and compliance with local building codes.
If you experience weak airflow, temperature inconsistencies, or a sudden rise in energy bills, your ductwork might be the culprit. Damaged or outdated ducts can allow air leaks, making your HVAC system work harder than necessary. A professional assessment can determine if repairs or a full replacement would improve efficiency and indoor comfort.
A pool heater lets you enjoy swimming in comfortable water temperatures year-round. It extends your pool’s usability beyond summer, allowing for more relaxation and entertainment options. With gas and electric models available, you can select an option that best suits your home’s energy needs and budget.
Excess moisture in the air can make your home feel damp, encourage mold growth, and create an uncomfortable living environment. A dehumidifier removes excess humidity, helping to maintain balanced indoor air conditions. This not only enhances comfort but also protects your home from moisture-related damage.
If your home has poor airflow, strange noises coming from your system, or uneven cooling and heating, your air handler might need attention. An inefficient air handler can reduce your HVAC system’s overall performance and increase energy costs. Professional repair or replacement can restore airflow and improve home comfort.
Indoor air quality testing helps identify harmful pollutants like dust, mold, and allergens that could be affecting your health. Poor air quality can lead to allergy symptoms, respiratory issues, and general discomfort. A professional assessment can determine the best solutions to improve your home’s air, such as advanced filtration systems or better ventilation.

Performed maintenance on a 2021 Goodman heat pump system. Completed full system maintenance including checking amperage and temperature, cleaning the drain pan, vacuuming and flushing the drain lines, and rinsing the condenser coil. During inspection, the contactor was found to be pitted. The customer approved replacement, and the contactor was replaced today. Surge Protection was recommended for the indoor air handler. Customer approved, and the surge protector was installed at the indoor unit. System is operating properly at this time.
Performed a full unit inspection on a 27-year-old 3-ton Trane heat pump system. At the time of inspection, the system was operating in cooling mode; however, after checking system pressures, subcooling, and superheat, I found the system is slightly low on refrigerant. This system uses R-22 refrigerant. I checked system pressures, subcooling, superheat, temperature split, compressor amperage, condenser fan motor amperage, blower motor amperage, and inspected all electrical components. During inspection, I found a burnt wire connection at the condenser capacitor that requires repair. I also found the condenser contactor badly pitted and in need of replacement. The electric heat strip contactor is also heavily pitted and should be replaced. Inside the air handler, I found heavy microbial growth throughout the cabinet, evaporator coil, and interior panels/covers. I performed a complimentary leak search and located a refrigerant leak at the evaporator suction line area. The evaporator c
Performed diagnostic on a 2.5-ton Goodman unit, approximately 10 years old. Upon arrival, found that the customer’s parent had been performing A/C maintenance and, after working on the blower, had placed a capacitor wire on the wrong terminal. This caused the blower motor to not operate properly. Corrected the wiring by relocating the wire to the proper capacitor terminal, then tested system operation. Blower started and ran properly after repair. Performed full system check, including system pressures, subcooling, superheat, blower motor amperage, condenser fan motor amperage, and compressor amperage. System is currently operating within normal range and cooling properly at this time. During unit inspection, observed that the condenser coil is heavily compacted with lint due to the dryer vent discharging too close to the condenser. Recommended condenser coil cleaning and rerouting or extending the dryer vent discharge away from the outdoor unit to prevent future airflow restriction
Underwood AC Installation (under previous homeowner) 2.5 Ton 14.3 SEER Goodman Split Heat Pump Condenser: GSZB403010A: 2301070673 Air Handler: AMST30BU14: 2301014444 T4 thermostat & 5 kw heat. Performed a diagnostic on the system due to a water leak complaint. Upon arrival, the customer advised that he had already attempted to clear the drain line by vacuuming it out, and the system was running at that time. After inspection, I found the return to be soaked and wet, confirming the drain line had been clogged. I presented the customer with options for drain line cleaning, a one-time maintenance service, or a service agreement. At this time, the customer chose to proceed with a one-time maintenance service. Since the customer had already successfully unclogged the drain line, I completed a full one-time maintenance on the system. Tested system operation in cooling mode and checked system pressures, subcooling, superheat, temperature split, compressor amps, condenser fan motor amps,
Performed a chemical cleaning of the condenser coil. Removed all condenser covers, thoroughly rinsed the coil, applied coil cleaner, and ensured all cleaner was fully washed off before reassembling the unit. Recommended removing and cleaning the blower wheel; customer approved. Pulled out the blower wheel, cleaned and sanitized it thoroughly. Applied microbial treatment and cleaned/sanitized the entire air handler cabinet, including the drain pan and accessible wiring. Installed a UV light system with a separate transformer. Tested UV operation and confirmed proper functionality. Tested full system operation, including: * System pressures * Subcooling and superheat * Temperature split * Compressor amperage * Fan motor amperage At this time, the system is operating properly. All components are clean, sanitized, and functioning within normal parameters.
Performed a diagnostic on a Boreal mini split system due to error code C0. Upon inspection, I checked system pressures and found the unit completely out of refrigerant, reading approximately 3 PSI. Based on the condition of the system, I recommended full equipment replacement. The customer agreed to receive a proposal. I contacted the office to submit the lead, and Kenneth provided the proposal to the customer. At this time, the unit is temporarily down and not operational.
Performed preventive maintenance on a package unit located in Franklin. Inspected and tested system operation in cooling mode. Checked system pressures and verified proper temperature split. Inspected electrical components including contactor and capacitor—both are operating within normal condition. Measured compressor amps, condenser fan motor amps, and blower motor amps; all readings are within manufacturer specifications. Cleaned and rinsed the condenser coil and removed debris from inside the condenser compartment to ensure proper airflow and efficiency. Cleaned the drain pan and flushed the drain line, then applied Viper treatment to help prevent buildup. Verified UV light is operational and functioning properly. Confirmed surge protector is installed and working as intended. At this time, the system is operating properly with no issues found.
Performed a diagnostic on a Tottukool air conditioning system due to the customer’s complaint that the air handler fan motor was running continuously. Upon inspection, I found that the customer had recently replaced the thermostat and wired it incorrectly. The electric heat wire (white wire) was connected to the wrong terminal (W1). Since this is a heat pump system, I relocated the white wire to the correct auxiliary heat (AUX) terminal. After correcting the wiring, the system began operating normally. I tested the system in cooling mode and checked system pressures, superheat, temperature split, compressor amperage, condenser fan motor amperage, and blower motor amperage. All readings were within normal operating range, and the system is running properly at this time. The customer expressed interest in a maintenance agreement. However, the property is co-owned with his brother, and he will need to discuss it with him before making a decision. The customer stated he may contact us i
