Quick answers

Cooling faults, heating faults and heat pump faults have little in common — start with the right page.
Refrigerant is not consumed in normal operation: a correctly charged system that loses it has a leak, and a top-off without diagnosis is not a permanent fix.
No-heat faults often trace back to ignition components, flame sensors or safety lockouts.
Complaints blamed on equipment can turn out to be duct leakage or undersized return air.
Ask for the measured numbers: temperature split, static pressure, refrigerant readings.

Which repair do you need?

Morgan Hill homes run three kinds of central systems: a gas furnace paired with an air conditioner, an all-electric heat pump, or mini-split zones. Each fails in its own way, so each has its own detailed page:

AC Repair — Not cooling, blowing warm air, won't start, short cycling, ice on the lineset, refrigerant problems.
Furnace Repair — No heat, cold air at the registers, ignition faults, short cycling, blower noise, safety lockouts.
Heat Pump Repair — All-electric systems that heat and cool from the same outdoor unit: stuck modes, defrost problems, ice that never clears, rising electric bills.

Not sure which you have? If a gas meter feeds the home and heat comes from a closet, garage or attic cabinet with a flue, it's a furnace. If one outdoor unit runs in both summer and winter, it's a heat pump.

Problems shared by every system

The blower, filter, thermostat and ductwork serve every mode. When heating and cooling both feel weak, when the same rooms are always uncomfortable, or when airflow at distant registers is poor year-round, the duct system is a more likely culprit than the equipment. A clogged filter or a thermostat wiring or configuration fault can also imitate an equipment failure in any mode. See do I need new ductwork? for the symptoms that point at distribution rather than equipment.

Annual service splits by mode: cooling in spring, heating in autumn. Both visits should end with measured readings rather than a verbal all-clear.

When repair stops making financial sense

On a newer system in otherwise good condition, repairing a single failed component can often make sense. As equipment ages and repair costs climb — compressor failure, a leaking evaporator coil, a confirmed cracked heat exchanger, obsolete parts, or significant refrigerant work on an R-22 system — comparing the repair with replacement options becomes more important. Repair vs. replace walks through the factors, and HVAC system lifespan covers what to expect from equipment age here. If replacement is the answer, start with HVAC replacement in Morgan Hill.

Common questions

Is my problem an equipment problem or an airflow problem?

If both heating and cooling feel weak, or the same rooms are always uncomfortable year-round, the duct system is a likely contributor. If only one mode misbehaves, the fault is usually in that side of the equipment.

How often should heating and cooling equipment be serviced?

Once a year for each mode: cooling in spring, heating in autumn before the first cold week. A heat pump covers both modes year-round, so annual service matters even more there. A real visit ends with measured readings, not a verbal all-clear.

When does repair stop making financial sense?

There is no fixed rule. Compressor failure, a leaking evaporator coil, a confirmed cracked heat exchanger, or major refrigerant work on an obsolete R-22 system are the points where pricing the repair against replacement is worth doing. Equipment condition, repair history, parts availability and how long you plan to stay all belong in that comparison.
