Hello all, my first post so go easy.
I currently have an old Lennox HP20-261 2 stage heatpump system. I have a few questions if anyone has the time to answer.
First, there is a problem with the external heatpump, in winter time (florida), it freezes up into a solid block of ice. The defrost never kicks in. Could this be a problem with the thermostat or is there a thermal sensor on the external unit that needs replacing? Is so, could you suggest a place to get the part?
Secondly, this system runs constantly in the summer. It runs, and runs, and runs, and I know for a fact it has a leak. I have had several companies out here to look at the unit and they always try to sell me a whole new one or say I need to replace the entire system or coil. They never can tell me exactly where the leak is. Every time I press the issue it's always a generic response like "somewhere in the coil". I understand the business better than they think, but I am stuck using a very limited list of contractors at my location (two). Each contractor works with the other to "milk" as much money from people as possible. I am no fool. I plan on renting this place out in a year so I have no interesting in replacing the entire system, I just want an honest assessment, and to fix the leak. I find it impossible to find an honest contractor here in my FL area. Commission outweighs honesty here by a factor of 10. Can anyone explain how I should speak to the technician? What exactly I need to ask for to have them find the leak? If they say it's in the coil should I ask if it's a specific part of the coil? Etc... Thank you!
