Replacement is a bigger decision than repair — and the quotes you'll collect can vary wildly for reasons nobody explains. Here's what actually drives the number, so you can compare quotes like someone who knows the game.
Cooling capacity should come from a real Manual J load calculation: your home's square footage, insulation, windows, orientation, and OC microclimate. An oversized system costs more upfront AND runs worse — short-cycling, poor humidity control, uneven rooms. Beware anyone who sizes by 'what was there before' without measuring anything.
Higher efficiency costs more upfront and saves more monthly. Whether the upgrade pays off depends on your usage and how long you'll stay in the home — a real conversation, not an automatic upsell. Inland OC homes with heavy summer cooling loads see the payback faster than mild coastal ones.
Replacing just the outdoor condenser is cheaper than condenser + indoor coil + furnace/air handler — but mismatching new outdoor equipment with an old indoor coil often sacrifices the efficiency you're paying for, and can void warranty coverage. Sometimes the honest answer is the bigger scope; sometimes it isn't.
A new system pushing air through leaky, undersized, or contaminated ducts can't deliver its rated performance. We evaluate ductwork as part of every replacement quote — sometimes it's fine, sometimes sealing or replacement genuinely belongs in the project. Either way you'll know why.
Permits, disconnect boxes, breaker sizing, and code updates are real parts of a legitimate install. Quotes that come in suspiciously low often get there by skipping permits — which surfaces later during home sales and insurance claims.
We install Rheem, Trane, Lennox, and Mitsubishi across different price tiers. The honest truth: proper sizing and installation quality affect your comfort and costs more than the badge on the unit. A mid-tier system installed right beats a premium system installed wrong, every time.
Ask every bidder the same four questions: Did you perform a Manual J load calculation, or size from the old unit? Is the indoor coil included, or just the condenser? Is the permit included? Is ductwork evaluated? The cheapest quote that skips those isn't actually cheaper — you just pay the difference later in comfort, bills, and problems. Our quotes answer all four in writing, and the price holds for the scope quoted. That's Tom's Word.
A useful rule of thumb: multiply the repair cost by your system's age in years. If it exceeds replacement cost, replacement deserves a real look. We'll show you the honest math either way — our techs don't earn more by steering you toward the bigger job.
Different overhead, different commission structures, different corners being cut. A dramatically low quote often means skipped permits, no load calculation, or mismatched equipment. A dramatically high one often funds heavy advertising and sales commissions. Ask every bidder what's actually included.
Yes — through NEIF, Wisetack, and Synchrony, including 0% options on qualifying systems. Our price is the same whether you finance or pay directly.
Often, especially for heat pump conversions — federal tax credits, TECH Clean California, and utility programs. We find what you qualify for as part of the quote; it's real money and most companies don't bother.
