A Martinez homeowner on Pomona Avenue called us because the old HVAC system had stopped being a system and started being a recurring bill. It ran loud, leaned hard on the electric meter, and could not hold a setpoint. The service calls were stacking up. They wanted to know whether one more repair would settle it down.
The compressor was the end of the line, not a fix
My $75 diagnostic put a gauge set and an amp clamp on the existing equipment, and the picture was plain. The compressor on the cooling side was failing, and the duct connections at the air handler had worn loose. I could have quoted a compressor swap. I did not. The rest of the equipment was old enough that a compressor today buys you a blower motor or a coil leak next season. When the repair cost starts chasing the replacement cost on tired equipment, the rule I use is to replace.
So we priced both in writing, line by line, and replacement won on its own merits.
A 3-ton Goodman heat pump, sized to the house and not to a catalog
The homeowner wanted heating and cooling on one platform instead of a furnace plus a separate AC. A heat pump gives you that at better efficiency than the two-box approach. I ran a Manual J load calculation on the house and it landed at 3 tons, so a 3-ton Goodman high-efficiency heat pump matched the requirement without oversizing it into short, sloppy cycles.
The work that went in:
- Goodman 3-ton high-efficiency outdoor condenser, sized to the load calc
- Matched 3-ton indoor air handler, factory-charged for R-410A
- New R-410A refrigerant linesets, because the old copper was not worth carrying forward
- Ductwork reconnected and resealed at the air handler, every joint we touched sealed with HVAC-grade mastic
- Smart thermostat with heat-pump-aware staging
- New high-voltage disconnect, whip, and a surge protector
Before any refrigerant went into the loop, we vacuum-pulled it and held a pressure test to confirm it was clean and tight.
The charge got weighed, not guessed
Most of a heat pump install happens where the customer never looks. The vacuum, the lineset brazing, the panel work, the duct sealing. Those are the spots a cut-rate crew shaves time, and two of them decide whether you actually get what you paid for.
The refrigerant charge was weighed to factory subcool spec, not topped off until it felt about right. That gap is the difference between rated efficiency and roughly 85 percent of it, every hour the unit runs. The duct joints got mastic instead of foil tape. Tape dries out and lets go in a couple of years. Mastic holds for the life of the system.
We started the system under load, watched it run for an hour to confirm steady-state operation, and walked the homeowner through the new thermostat before packing up.
One system, lower bills, and a real warranty behind it
The house now heats and cools off a single quiet platform that pulls noticeably less power than the old setup. Because it is sized correctly, it runs clean cycles. The equipment carries our 10-year parts and 10-year labor warranty plus the Goodman factory equipment warranty.
If you are weighing repair against replacement on aging equipment, that is exactly the kind of call we lay out in plain numbers before you commit. You can read more about how we approach heat pump installs. On the rebate side we work with BayREN, MCE, PG&E, and EBCE/Ava plus manufacturer instant rebates. Amounts and funding vary by territory and cycle, so we confirm what is actually paying when we write your estimate. Bigger HVAC jobs like this one run through our HVAC division, Bay Area HVAC Service.
