Performed $29 tune-up on system. Discovered frozen evaporator coil caused by clogged secondary drain and active water leak. Noted failing inducer motor and hot surface ignitor. Recommended full system replacement due to repair costs and equipment age. Discussed upstairs bedroom cooling issues with customer and explained additional diagnostic options.
Performed routine furnace tune-up on Bryant system. Conducted comprehensive inspection including heat exchanger evaluation, combustion analysis, gas pressure verification (HI/LO stage), flame sensor and burner examination, and blower motor assessment. System operating normally with no immediate concerns identified. Cleaned pressure switch and confirmed proper thermostat operation. Air filter in moderate condition. Documented system components with photos of main humidifier unit, ductwork, and associated electrical connections.
Diagnosed main zone heating deficiency and determined inadequate airflow was preventing the home from maintaining desired temperature. Reviewed zone controller settings and identified insufficient CFM values. Increased blower speeds across all zones to improve heating performance, resulting in successful temperature regulation at the main level.
Diagnosed insufficient heating on main level of home with recently installed boiler system. Identified circulation issue with main level zone. Replaced existing pump with Grundfos model after determining original pump was causing noise through piping when operating at higher speeds. Verified proper operation of all zones and actuators after replacement. System now functioning normally with adequate heat distribution.
Diagnosed and resolved main level heating issue by replacing seized zone valve actuator. Verified proper boiler operation with supply temperature at 170°F, return at 163°F, and system pressure at 16.6 psi. Cycled system and confirmed all zones now functioning correctly.
Completed warranty service on Mitsubishi mini split system (Model MUFZ-KJ12NAHZ) requiring replacement of failed temperature sensors. Successfully installed new CN641 (Defrost thermistor and temperature discharge thermistor) and CN643 (Ambient temperature thermistor) components on the outdoor condenser unit, restoring proper system operation under full warranty coverage.
Cleared kitchen sink clog in right basin where garbage disposal was blocked. Removed accumulated food debris causing the obstruction, restoring proper drainage and disposal function.
Performed complimentary furnace tune-up and inspection on 4-year-old unit as courtesy for previous water heater installation. Comprehensive evaluation confirmed proper operation with strong igniter, functional draft and blower motors, and sound heat exchanger, control board, and gas valve. Identified weak flame sensor requiring replacement; customer requested email quote for proactive replacement.
Responded to call for low water pressure throughout residence. Upon inspection, determined malfunctioning water softener was causing significant pressure reduction. Bypassed the softener system to restore normal water pressure. Discussed installation options for a new pressure reducing valve to properly regulate home water system and ensure consistent pressure. Customer advised on benefits of replacing the non-operational water softener.
Responded to warranty service call for Mitsubishi mini-split system in detached garage exhibiting no heat operation. Diagnosed severe ice accumulation on outdoor unit due to failed thermistors. Replaced defective thermistors under warranty, restoring proper system operation and resolving the abnormal frost buildup condition.
Performed diagnostic assessment on 12-year-old PowerFlex gas water heater that had previously stopped producing hot water. Customer had reset unit but status light continued flashing. While heater was operational at time of service, I confirmed error code persisted and documented age-related wear. Provided comprehensive replacement options, including tankless alternatives as requested by customer.
Responded to warranty service call for recently installed IBC boiler (20 days old). Customer reported insufficient hot water supply and inadequate heating on main floor despite thermostat settings. Diagnosed circulation issue in water heater zone and increased pump speed to resolve hot water depletion problem that was occurring after approximately 20 minutes of use.
Performed warranty repair service involving glycol addition to the boiler system. Drained water from the boiler, added water-glycol mixture, isolated and circulated the solution through basement and upper level loops. Confirmed proper glycol concentration and adjusted system pressure to 18 psi.
Responded to customer complaint of gas odor near regulator of recently installed furnace. Upon inspection, determined the regulator was properly venting as designed - this is normal operation, not a gas leak. Verified system safety and explained normal regulator function to customer.
Responded to homeowner's complaint of banging noises from recently installed IBC SL199 boiler. Identified air in system as the cause, purged all loops using transfer pump, verified proper zone valve operation, and set indirect tank to high priority. Reinstalled pressure relief valve in vertical orientation to meet code requirements, resulting in normal system operation without noise issues.
