AC Tune Up in New Port Richey, FL
An AC tune up is the single most effective way to keep your cooling system reliable, efficient, and long-lasting, especially in a climate like ours. Here in New Port Richey, FL, air conditioners run hard for eight to nine months out of the year. That kind of demand wears down components faster than in most parts of the country.
R.J. Kielty Plumbing, Air, & Electric Inc. has been performing AC tune ups and full HVAC maintenance for homeowners and businesses across the region since 1973. We know what Florida humidity, salt air, and year-round heat do to cooling equipment. Our technicians inspect, clean, and optimize every part of your system, so it performs the way it should, before a small issue turns into an expensive emergency call.



What’s Included in Our New Port Richey AC Tune Up
Every AC tune up from R.J. Kielty follows a structured, multipoint process. We don’t cut corners or skip steps. Here’s exactly what our certified technicians do during each visit.
Complete System Inspection and Diagnostic Check
We start every AC tune up with a full visual and diagnostic inspection of your entire cooling system. This includes checking the indoor air handler, outdoor condenser unit, ductwork connections, and all mechanical components for signs of wear, damage, or buildup.
Our technicians use diagnostic tools to measure system performance against manufacturer specifications. If something’s off, a weak capacitor, a worn belt, an unusual vibration, we catch it here before it causes a failure. Early detection during a routine tune up saves our customers from costly mid-summer breakdowns.
Refrigerant Level Testing and Recharge
Low refrigerant means your AC has to work harder to cool the same space. That drives up energy costs and puts extra stress on the compressor, one of the most expensive components to replace.
During your tune up, we measure refrigerant pressure levels and compare them to the manufacturer’s recommended charge. If levels are low, that usually points to a leak somewhere in the system. We locate and address the leak, then recharge the refrigerant to the correct level. This step alone can improve cooling output by 10–20%.
Condenser and Evaporator Coil Cleaning
Dirty coils are one of the top reasons AC systems lose efficiency. The outdoor condenser coil collects dirt, pollen, grass clippings, and debris, all common around New Port Richey homes with lush landscaping and oak-lined yards. The indoor evaporator coil attracts dust and moisture, which can lead to mold growth over time.
We clean both coils thoroughly during every AC tune up. Clean coils transfer heat more effectively, which means your system cools faster and runs for shorter cycles. That translates directly to lower electric bills.
Thermostat Calibration and Performance Verification
A thermostat that reads even two degrees off can cause your system to short cycle or run longer than necessary. We test your thermostat’s accuracy against a calibrated reference and adjust it if needed.
We also verify that the thermostat communicates correctly with both the cooling and heating stages of your system. If you’ve upgraded to a smart thermostat, our technicians confirm the programming matches your schedule and comfort preferences.
Electrical Connection Tightening and Safety Check
Loose or corroded electrical connections create resistance, which generates heat and increases the risk of component failure or fire. Florida’s humidity accelerates corrosion on wiring and terminals faster than drier climates.
Our technicians inspect all electrical connections, tighten terminals, and test voltage and amperage on motors, compressors, and contactors. We also check the capacitor and relay switches. This electrical safety check is a critical part of every AC tune up we perform.
Air Filter Replacement and Airflow Optimization
A clogged air filter restricts airflow, forces your system to work harder, and allows dust and allergens to circulate through your home. We replace the filter with the correct size and MERV rating for your system.
We also measure airflow at supply and return vents. If airflow is weak or uneven, we check for blockages in the ductwork, closed dampers, or blower motor issues. Good airflow is essential for even cooling throughout your home or commercial space.
Condensate Drain Line Clearing and Treatment
Florida’s humidity means your AC produces a large volume of condensation. The condensate drain line carries that moisture away from the system. When the line clogs, and it will, especially with algae growth common in our warm climate, water backs up into the drain pan and can overflow onto ceilings, walls, or floors.
We flush and treat the condensate drain line during every tune up to prevent clogs and water damage. This is one of the most overlooked maintenance items, and one of the most common causes of service calls we see.
