Customers sewer line backed up. Used front clean out to access sewer and perform camera inspection. Went less than 10’ and saw roots. Used cable to break up and try to retrieve root obstruction to properly quote for repairs. Was able to remove majority of roots on customers side, but told customer to contact the city to also evaluate their side as well.

Customer called us out for a toilet in upstairs bathroom that is not properly filling and flushing. I will have to perform a minor repair to this toilet to restore proper operation. I was successfully able to perform a repair to the toilet in the upstairs bathroom. I tested by flushing and running water and making sure everything is operating properly in the presence of the customer. Everything is in good shape. Customer had what appeared to be a mainline stoppage, but we cannot confirm until she first has septic company come out first to make sure the septic is not the issue. I also provided the customer with our ENDURE drain maintenance product. Customer is very satisfied.

I was called out to Richard & Martha‘s house for a cooling issue. Richard & Martha have lived here briefly so we performed a thorough evaluation. During the evaluation we discovered the zoned system had it’s bypass spring damper fall off which allowed air to flow right back into the system which would cause freezing problems which likely happened because there was water in the pan, the system is a single stage furnace with a 2 stage ac which is an inconsistent application, the flood protection was minimal, the ac was dirty, the dual capacitor has failed, and zoning is hard on the ac as it causes it to turn on and off more often than normal. Today I corrected all the issues I saw today, I adjusted the airflow, and I adjusted the refrigerant to get the system in good working condition.

Upon arrival customer stated that they were out of town and their second home came back to this home and found that house was 85 where they set it at when leaving and that when system turned on it was not cooling. After a full thorough evaluation of the 12 year old furnace and 12 year old ac and coil found that system was cooling in home on arrival. Customer had thermostat set and was within a 1 degree temperature of room temperature. This is a split level home and the only thermostat is upstairs in a bed room area, when this area satisfies theh it makes the whole house seem satisfied leaving a temperature difference between upstairs and downstairs. System needs to be a two zone system. Checked all operations of furnace, there is a lot of vibration from unit. Customer recently washed reusable (16x25x1) system filter. Blower wheel does have dust build up on it, when blower does get cleaned the gas to home would have to turned off due to gas line blocking from pulling it out of cabinet.

System is not over 10 years old. System is fine. Needs a small amount of refrigerant. Leak search maybe needed in the future if refrigerant is needed again or system freezes up. With the building owner’s permission I added the refrigerant and advised them that when it gets extremely hot outside hvac systems in general will not be able to temperatures indoors in the low 70’s. Also advised the building owner/business owner that this summer has been hotter than normal and many hvac systems may struggle to keep houses/buildings cool this summer.

Completed system observation by the time of arrival the client said that the unit was leaking water into the emergency drain pan by performing and diagnostic tested condensing pump tested drain. Inspected drain pan for any cracks, tested refrigerant pressure inspected evaporator coil tested condensation pump. Tested the unit on heat mode for over an hour to see if the coil will build ice or blower motor will stop at any moment, causing the evaporated to freeze Advise client if the unit act up the next time to take a video and pictures of the system. It looks like at some point coil froze up leaking some of the water into the emergency drain pan.
