Have either of the technicians that's been out bothered to clean the condenser coils? Whether or not this is a direct contributor to your troubles, if you plan to keep this condenser and swap out the compressor, the outdoor and indoor coils should be cleaned.Originally posted by secstate
No hard start kit installed (at least since I have owned the house which is about two years). First tech said the problem was a "cracked valve" the second tech said "worn valves".Originally posted by tinknocker service tech
75/185 at 85 degrees outside and cooling fine
i must be missing something what did he say was wrong with the compressor and did he install a hard start kit
If I were the technician at your home here's what I would check before condemning the compressor:
a) Allow compressor to start and run normally. Observe startup and running amperage draw.
b) Record pressures, superheat, and subcooling readings after system has been online awhile and has balanced out. Check temperature of lines across reversing valve to indicate any bypassing of refrigerant.
c) Note temperature rise over outdoor coil.
d) Note temperature drop over indoor coil.
e) Note condition of outdoor and indoor coils, and condition of indoor blower wheel. Note any restrictions to indoor air flow (return duct collapse, supply register dampers closed, etc)
f) De-engergize system and observe time involved for system to equalize. Note whether system uses TXV or piston in either or both coil sections (being a heat pump).
g) Check strength of capacitor.
h) Check integrity of compressor motor windings.
i) Check condition of compressor contactor.
j) Check condition of compressor terminals for any corrosion or burning of wires.
k) Backwash condenser coils.
l) Restart unit and observe all conditions after balance-out.
m) Stop unit and allow five minutes to equalize. Restart.
0) Give customer options according to my findings.
That might seem like a lot for a tech to do on a service call where he feels rushed for time due to a high stack of tickets sitting in the passenger seat of his van. If he's experienced and skilled he can knock out these checks with ease and arrive at an informed diagnosis rather than tossing out "Uh...sometimes they just do that."
