When a new system makes more sense than another repair
We repair more units than we replace, and we will always be upfront if a repair is the smarter move. But there are situations where a new system is the honest recommendation. If your equipment is 15 or more years old, you are past the expected lifespan. Parts get harder to source. Efficiency drops every year. What used to cool your home on $120 a month now costs $180.
If your system uses R-22 refrigerant, that is an even stronger signal. R-22 production ended in 2020. A single pound now runs $100 or more, and a typical recharge requires 3 to 5 pounds. At $300 to $500 per recharge, with the leak that caused the loss still present, you are throwing money away every season.
Other indicators: repair costs exceeding half the replacement value, uneven cooling with hot and cold rooms, the system running nonstop without reaching the target temperature, or breakdowns more than once per summer. Many homes in Rockridge and along Piedmont Avenue were built in the 1940s and 1950s with AC added later as a retrofit. Those systems are often undersized for the home. Newer condos in Uptown and Jack London Square have more modern equipment, but some of those early builds already have 10-year-old systems showing their age.
Not sure whether to repair or replace? Call us at (510) 555-0193. We will evaluate the system, show you the numbers for both paths, and let you decide. Zero pressure. If repair makes better financial sense, we will say so. Keep your system running longer with regular AC maintenance.
How we size your new AC system in Oakland
Most HVAC companies skip the sizing calculation entirely. They check the old unit, match the tonnage, and install. That is how you end up with an oversized system that short cycles, wastes energy, and fails to control humidity. Or an undersized system that runs nonstop and still cannot keep up when Oakland hits 95°F during September.
We perform a Manual J load calculation on every installation. That is the engineering standard for residential HVAC sizing. We measure your home's square footage, insulation values, window area and orientation, ductwork condition, and occupant count. Then we factor in Oakland's specific climate: IECC Climate Zone 3C, marine influence from the Bay, afternoon sun exposure on hillside homes, and the inland heat spikes that hit neighborhoods east of I-580.
The result is a system sized precisely for your home. Not too big, not too small. It runs efficiently, manages humidity properly, and keeps every room within 2 to 3 degrees of the thermostat setting. That is how a correctly sized system should perform.

What a new AC system costs in Oakland
We are going to be direct about pricing because most companies will not. Entry level: $4,800 to $7,000. That gets you a 14 SEER2, single-stage system. It is builder grade, similar to what was originally installed in many Oakland homes. It works. It cools. It is reliable. If budget is the top priority, this is a solid option.
Mid-range: $7,000 to $9,500. A 16 SEER2, two-stage system. Better humidity control, quieter operation, lower monthly bills. The two-stage compressor runs at a lower speed most of the time and ramps up only on the hottest afternoons. This is our most popular install in Oakland because it balances cost, efficiency, and comfort for this climate.
High end: $9,500 to $15,000. An 18+ SEER2, variable-speed system. Very quiet. Peak efficiency. The compressor adjusts continuously to match the exact cooling demand. These systems can cut your cooling costs by 40 to 50 percent compared to a 15-year-old unit. Popular in the Montclair hills and larger homes along the Piedmont Avenue corridor.
Your PG&E bill will drop $30 to $70 per month with a high-efficiency system compared to a 15-year-old unit. Over 10 years, that is $3,600 to $8,400 back in your pocket. Factor that into the purchase price when weighing your options.
Brands we install across Oakland
Trane, Carrier, Lennox, Rheem, Goodman, Daikin, American Standard. We are not locked into a single manufacturer. Some companies are. They are dealers for one brand and that is all they will quote you, regardless of whether it fits your situation. We recommend based on your budget, your ductwork capacity, and what performs best in the East Bay climate. If a $5,500 Goodman is the right call for your house, we will say that instead of pushing a $11,000 system you do not need. If your current unit just needs a fix instead of a full replacement, take a look at common reasons your AC is not cooling.
