We've had some issues with our heat pumps and Jake @ Interstate has been very helpful with explaining and resolving the issues. Jake is always professional and courteous. We particularly appreciate Interstate's efforts to get to our home quickly to resolve the matter during our frigid weather. Thank you!
I arrived for a blue member heat pump issue. I first spoke with the homeowner and found that the heatpump will run but it has a lot of ice buildup on the system. I inspected the system and found the timing to have been set at 90 min. I changed it to 30 min defrosted time. I also rechecked the thermostat settings and we set the heatpump lock out at 35 deg. I explained how the system operates and that the outdoor system dose run during defrost mode.
I arrived for a blue member no heat call. I first inspected the system and found the heat pump to have a refrigerant leak at the outdoor system. This was locking the compressor out and preventing the system from running. The condenser fan motor is also showing signs of overheating and the motor is over amping. I recommend to replace the outdoor system to avoid future breakdowns with this system. We discussed the differences in all systems and we decided to install a two stage as/heat pump. This outdoor system will come with a 10 year parts warranty and a one year labor warranty. We will clean up the wiring inside the furnace cabinet and in the thermostat housing. We will also replace the thermostat so that we can control the system in all modes.
I arrived for a blue member system not running. I first spoke with the homeowner and found that the outdoor heat pump will not run. I checked the systems operation and found that the thermostat was set to not operate the heat pump below 35 deg. I then explained the systems operation to the homeowner and how a heatpump system operates. They mentioned that the lights do dim when the heat pump kicks on. I offered to install a hard start kit on this system to help the system fight the start up amps. We decided to install the hard start kit on this system. I then cycled the system in heatpump mode and emergency mode and found no issues with the systems operation at this time.
I arrived to perform a non-member tuneup on a furnace. After speaking with the customer found out that they have three furnaces in the home. All three furnaces were located and I did my tuneup on all three. The east furnace is in good operating condition the attic furnace needs a capacitor it is 3.1 out of 5 ÂµF the garage furnace is in condition. I checked all amp draws voltages all blower wheels are clean gas pressures are within spec only one capacitor out of the three furnaces and that is out of spec resurfaced all flame sensors all igniters are within spec as well. The customer has declined the capacitor replacement and she will give us a call when she figures out if her warranty company will cover the capacitor and have us perform the work. The customer also declined all three memberships due to the fact that they are selling the home.
Dual system Blue shield protectiion plans for fall maintenance. Both systems have 90% propane gas furnaces and heat pumps. Pulled all washable filters. Filter in upstairs sun deck is still. A pleated 12x12 and replaced. Washed out all filters and set in sun to dry. Downstairs; checked and cleaned flame sensor on American Standard. Opened blower cavity and checked capacitors. Checked and inspected drain and flue. Checked evaporator coil and float switch. Cycled system on and off between emergency heat to check propane and heat to check heat pump in reverse mode. Replaced gas cap after checking propane gas pressure. Heat pump fan motor capacitor reading low at 3.7/5 mfd, with customer permission I replaced it. Checked amp draws inside and outside at starting, high and low speeds. Replaced filters after they were dried. Upstairs; checked and cleaned flame sensor on Amana 90% gas furnace. Opened blower cavity and checked insulation. Checked and inspected drain and flue. Checked evapor
Came out to call. I was out to do the maintenance recently on the units. Customer said East unit had stopped working and was making a noise. I checked system over and found the system had locked itself out. I reset condenser and cooled down the compressor. System came back on but was freezing up quickly. I checked equipment in attic and found the variable speed motor not ramping up like its supposed to and was barely blowing any air. I reset module plugs and cycled it on again. Motor started and was operating properly. Discussed with customer about the module on the motor possibly malfunctioning, but it was operating after I reset the plugs. We talked over options, and customer wants to wait and see how it operates over the weekend. I will keep ticket open and have the model number on file in case I need to order it. Return to install previously recommended ecm motor replacement recommended by Isaac. Install new motor tested amp draw and verified motor is ramping up to correct speed.
Performed preventative maintenance on 2 AC systems. Took out and washed customers electrostatic filters. While I let those dry I inspected the blower assemblies, electrical components, wiring, evaporator coils, drains, ducting, and overall condition of equipment in home. Reinstalled filters. Checked and tested thermostat operation, amps, temperatures and pressures of condensers. Checked capacitor, compressor, contactor, fan motor, and control boards. Cleaned condenser coils thoroughly. Both systems are cooling properly within manufactured specifications at this time.
Arrived to not cooling well service call performed system evaluation. Found system slightly low refrigerant. Spoke with customer. Customer chose to add refrigerant. With customer approval added 14oz r22 to system. System cooling at this time. Washed condenser. Customer will replace filters. System running as designed. If system becomes low on refrigerant in near future I suggest leak repair be performed.
