I had another AC company come out an inspect the unit HAAP installed. This is what the report stated: ent to look at heat pump system in the apartment. Outside I found the condenser line set to be kinked, uninsulated, the wrong size and the system to already have dye added to the system so someone has tried to leak check the system. The problem with the dye is that it should never be used in a system because it contaminates the refrigerant and the oil in the unit, these actions have taken years off the operation of the unit. Inside starting at the thermostat to be wired incorrectly which may be a leading cause to why the system is running incorrectly. Also found that part of the ductwork was cut out of the way by the previous company and they did not put the duct work back together and in fact just covered the whole on the end of the duct. The line-set is wrong as it is suppose to be 3/8 3/4 line-set and it is only 1/4 1/2 line-set which leads to less life of the system and improper running of the system. In order to fix the system we would have to reclaim any refrigerant from the system and then un do the brazed connections, run line hide, drill out the building pull new thermostat wire and a new line-set between the two units, braze pull a vacuum, charge the system and then re wire the system.

Septic system installations and replacements FAQs

A septic tank typically lasts 15 to 20 years, depending on the materials used, maintenance frequency, and soil conditions. Regular inspections, proper pumping, and careful water usage can extend its lifespan. Professional maintenance ensures your system remains efficient and helps prevent premature failure.

Your septic tank should be pumped every three to five years. In fact, the recommended interval for pumping is every three to five years, as this schedule effectively prevents the buildup of solids and maintains the system's performance. Factors such as household size, water usage, and the capacity of the tank can influence this interval. Adhering to a regular pumping schedule minimizes risks of backups and system overload, ensuring efficient operation and longevity of your septic system.

Your septic system shows signs of failing when you detect noticeable odors and unusual moisture or overly green patches in your yard. In essence, clear indications such as unpleasant smells, gurgling noises from the plumbing, and areas of excessive vegetation or saturation signal that the system may be compromised. Additional symptoms include slow drainage and standing water near the drain field. These warning signs require immediate professional evaluation to prevent severe damage or environmental hazards.
