Dependable and competent

Daniel always does a wonderful job maintaining the air conditioner and furnace. It’s wonderful knowing we’re set for another season of heat and humidity! I highly recommend Charlie’s air-conditioning and heating.

Upon arrival found system in a high pressure lockout, found coil guard foam out of place and keeping condenser fan motor from spinning, readjusted foam and strapped down with zip ties, checked charge and pressures look good System is cooling at this time

Performed spring HVAC maintenance on a 2.5-ton split system. Cleaned condenser coil with a non-acidic coil cleaner, replaced a 16x25x1 MERV 11 filter, and confirmed refrigerant charge at 122/345 psi for R-410A. Checked capacitor values (uf readings were within 5% tolerance), verified amp draw on compressor and fan motor. System operating within manufacturer specs.

Responded to no-cooling call on a 4-ton Goodman package unit. Found a failed dual-run capacitor (rated 45/5 µF, tested 0/3). Replaced with new Titan Pro and restored compressor operation. Also noted dirty evaporator coil causing high head pressure. Scheduled coil cleaning and verified airflow at 925 CFM across return. System cooling properly post-repair.

Spring tune-up on a York Affinity Series 3-ton heat pump. Checked reversing valve function, confirmed low voltage integrity, and recalibrated smart thermostat settings for heat pump staging. Refrigerant pressures were 118/328 psi at 68°F ambient. Also flushed condensate line with compressed nitrogen and verified slope on PVC drain run.

York system retrofit in a 1970s ranch home. Removed outdated R-22 unit and installed a 16 SEER2 York single-stage AC with matched indoor coil. Brazed in new line set, pressure tested at 350 psi with nitrogen, and pulled vacuum to 500 microns. System charged with 6.2 lbs of R-410A. Total static pressure: 0.56 in. wc. System running clean.

No heat call converted to full replacement after diagnosing a cracked heat exchanger and multiple rollout trips. Installed a new York TM9V modulating gas furnace. Verified combustion readings: CO < 5 ppm, O2 at 6.2%. Adjusted gas valve for 3.5” manifold pressure and confirmed ECM blower programming via dip switch settings.


Pete F.

Service call for a 5-ton rooftop unit at a medical office. Found faulty TXV sticking closed and low suction pressure (~45 psi). Replaced TXV and recharged system with 9.3 lbs R-410A. Verified superheat at 12°F and subcooling at 9°F. Also replaced contactor and added surge protector for circuit protection. Unit now performing to spec.


Justin T.

Customer reported low airflow. Inspection revealed collapsed flex duct near plenum and partially blocked return grill. Replaced damaged flex with 8” insulated duct, re-secured with zip ties and mastic sealant. Measured airflow increase from 480 to 830 CFM. Also replaced dirty filter and adjusted fan speed tap from medium to high.

Completed spring AC maintenance on a 2-ton Carrier unit. Condenser coil cleaned with foaming cleaner, amp draw on compressor at 8.1A (within range). Capacitor tested 39.6 µF out of 40 µF spec. Refrigerant levels normal. Checked float switch operation and cleaned drain trap. All components functioning as expected for cooling season.

AC system not cycling properly. Traced issue to failed thermostat wire shorting Y and G terminals. Re-ran 18/5 low-voltage wiring, sealed connections with silicone to protect against attic heat damage. System now starts and shuts off correctly. Also tightened loose wire nuts in air handler junction box. System tested through full cooling cycle.

Customer had high humidity and inconsistent cooling. Found blower wheel caked in debris and motor capacitor weak (tested 4.1 µF out of 5 µF). Removed blower assembly, cleaned wheel with degreaser, replaced capacitor, and reset blower speed for high cooling. Post-repair humidity dropped from 68% to 51% indoor RH within 2 hours.
