I believe that Joseph did all he could to repair the heating and air conditioning unit I have now so that I would not have to get a new unit.
He explained why this particular part needed tto be replaced
Luis was excellent! Explained everything about our “old” unit.
Service call that the Heat was not working and it may be a power related issue. Upon arrival spoke with homeowner about issue. Found thermostat calling for heat but the system was not running. Inspected unit and found system out on a 3 Flash High Limit Lockout code. Reset unit and tested. Air Supply temperature was exceeding 150 Degrees and causing unit to shut down on high limit safety. This unit has a multi-speed blower motor. Increased Blower Speed for heating to the highest Speed Tap. Put unit in operation and continued to monitor. Allowed system to run for over 15 minutes and Supply Temperature did not exceed 125 Degrees. The ductwork for these homes is undersized and causes the Temperature rise to be higher than normal.
Returned to site to replace the 4â€ Flexible Dryer Vent. Removed broken flex of Dryer Vent. Installed new 4â€ Flexible Aluminum Puncture & Rip Resistant Dryer Vent and sealed connections. Before installed new Vent, vacuumed accessible hard pipes dryer duct. Vacuumed Utility Closet and around HVAC system. Left Quotes for replacement of the system with homeowner to review. Payment for repair paid by Check. Check #: 9817 in the amount of $251.81.
Performed Precision Heating Tune Up on Through the Wall Gas Furnace. Replaced 16x25x1 Air Filter. Inspected electrical components on unit. Found upon arrival that dryer vent that hangs behind the unit was ripped and lint and dryer exhaust was emptying into the utility closet. Included estimate for the replacement of the Flexible Dryer Vent. Removed Supply Plenum and inspected heat exchanger. Found several rust spots on exterior of Heat Exchanger Tubing. Performed Combustion Test and combustion readings were within rating. Due to the rust on the Heat Exchanger would recommend replacement of the system before any failure of the heat exchanger occurs. Age of unit is about 10 Years Old.
Performed precision heat tune up on Rheem gas furnace. Replaced Aprilaire 413 air filter ( homeowner provided) checked all electrical components and connections. Cleaned flame sensor. Blew out condensate drain and pressure switch tubing. Checked temperature rise. Checked gas pressure. Performed combustion test. Found water heater is around 9 years old recommended replacement of water heater. Provided customer a quote. Gas furnace is working fine at time of inspection.
Performed six month quality check, replaced air filter. Started gas furnace tested limit and safety switches, performed combustion test. Explained thermostat. Cycled air conditioner. Everything is working fine.
Performed Quality Assurance inspection on a newly installed comfort pack system. Checked over entire system. No air leaks. No gas leaks. Wiring proper and secure. Checked fan speed. Itâ€™s set to medium high for heat and high for cooling. System running great at time of QA.
Checked thermostat, found set for 68 and reading 68. Julia stated that when she changed the temperature setting the room temperature would also change. Checked thermostat setup. Found nothing wrong with the thermostat. I explained that the thermostat is very accurate and just touching the thermostat can change the room temperature. Cycled furnace and checked operation.
Performed PECO check, checked air filter, found a new filter. Tested electric back up heaters. Blew out condensate trap and drain. Checked voltage, amperage and electrical connections. Started heat pump, calculated btu output getting 35640 at 52 degrees. Checked operation and temperature rise across coil.
Removed threw the wall heater. Installed a new comfort pack threw the wall heater and tested unit in all modes. Reconnected drain and installed a new ez trap and wired in to the unit. Reconnected gas piping and adapted as needed. Bubble checked all gas piping.
Checked no heat complaint, found thermostat set to off. Set to heat, furnace started and ran, after 5 minutes the furnace locked out on limit switch open. Inspected heat exchanger, see what may be a restriction in the second pass, see pictures. Checked limit switch it appears to be in good condition. Cycled furnace Iâ€™m getting a 148 degree supply and a 78 degree dt. I recommend replacing the limit switch first and if limit continues to trip a new heat exchanger will be needed.
Returned to site to get Signed Agreement for upcoming installation and collect Deposit for Installation.
Drained and removed old boiler. Installed new peerless gas boiler. Installed new circulator pump, isolation valves, shutoff valves, air eliminator, flow check, and new piping to existing heat runs. Installed new t6 thermostat. Ran new gas line and leak checked. Ran high and low volt wiring and installed new switch and receptacle. Tested boiler and performed combustion test, adjusted gas pressure. Purged all air. Boiler working well at time of install.
Returned to site to further investigate issue with the Furnace. Put system in heating mode and tested. Verified that system was shutting off on Limit after running for 5-10 Minutes. Removed Return Door Panel and Filter. Reset system and tested airflow with the Return open. Removed Supply Duct and allowed Supply Air to bypass the ductwork and blow into the room. Found unit would stay running with the Supply Duct off, but with only the Return open the unit would continue to shut down in limit. Noted a small increase from .95 Amps on the blower motor to .99 Amps on the Blower Motor with the Supply duct off. Cross referenced this unit with other units in the building and found this unit is sized larger. Other systems are 38,000 BTUs on the Furnace and this unit is 51,000 BTUs on the Furnace. This larger output of the Furnace may be too large for the ductwork. Inspected Indoor Coil and Blower Motor. Found some rust and corrosion on left side of coil. Had called manufacturer previously while
Service call that the Gas Furnace was not working again. Upon arrival found Indoor Temperature at 73 Degrees and the system was turned off. Turned system on to test operation. System fires up and operates but then will shut down from the Main Limit Switch at the Heat Exchanger. Tested combustion on system and measured gas pressure. Disassembled unit to access the Blower Motor. Tested Amp Draw on blower motor which was within rating. Blower was drawing 1.1 Amps and is rated for 1.4 Amps. Inspected Blower Wheel for debris or obstructions. Removed Supply Ductwork on top of the Unit to inspect the Heat Exchanger. Found no visible damage or failure points in the heat exchanger tubing.
Service call that the Heat was not running. Upon arrival found indoor temperature at 76 degrees and the system was turned off. Put system in heating mode to test. System began operating with no issues. Measured Air Temperatures on system. Found a Higher Temperatures on the Supply which was nearing the Limit Switch cut off. Increased Blower Fan speed to High Setting and increased blower off delay to 160 seconds to allow more heat dissipate from the unit. Inspected Heat Exchanger and found no blockages or damage. Inspected Air Filter on unit. Checked vents in apartment to ensure they were open and nothing was blocking them. Due to the warm outdoor temperature and the high indoor temperature this could be causing the higher temperature splits and causing the furnace to overheat and shut down on a Safety Limit. Would not run the Heater when the indoor and outdoor temperature is higher.
