@AHS_Warranty Don't give this company money. Our furnace died in single digit weather. They said we can have someone there in 3 days. Unacceptable we had to pay a real company $500 to fix our heater so we wouldn't freeze.
@AHS_Warranty the vendor you sent PROSERVICE HVAC & PLUMBING, strung us along for 3 months, when we complained they lied about what they saw. We called customer service and they said they would get another vendor. You assigned it to PROSERVICE HVAC & PLUMBING again.
@PcPhilanthropy A little over simplified, but if you ever see those old phones with a red button on the bottom for each line, each line needed a pair of wires. You'd have a connector like that on the back of the phone.
