Repair It Again, or Replace It Right?

When a system is aging and the repairs keep coming, the honest answer isn't always "replace." We help you run the numbers, then size and install a new AC, furnace, or heat pump by real load calculation, A2L-ready and built to last.

Run the $5,000 Rule on Your System

A trusted rule of thumb: multiply your system's age by the estimated repair cost. Under $5,000 usually favors repair, over $5,000 leans toward replacement. Slide in your numbers for a starting point, then let us confirm with an in-person look.

Leans toward replacement

At 6,000, the age-times-cost score is over 5,000, so putting this money into an aging unit usually isn’t the best value. A new right-sized system typically pays back in efficiency and reliability.

A guideline, not a verdict. Repair frequency, efficiency, R-22 refrigerant, and comfort all matter too, we weigh the full picture on-site with no pressure to replace.

● Signs It May Be Time

When Replacement Beats Another Repair

One of these alone might just mean a repair. Several together usually mean a new system is the better long-term value.

Age 12–15+ Years

Past the mid-point of its life, repair dollars start going into a unit near the end anyway.

Rising Energy Bills

Creeping summer bills often mean lost efficiency a newer high-SEER2 system would recover.

Frequent Repairs

Two or more service calls a season is money better applied to a reliable new unit.

Uses R-22 Refrigerant

R-22 is phased out and expensive to service, a leak on an old unit often tips the math to replace.

● Replacement Done Right

A New System Is Only as Good as the Install

● Common Questions

HVAC Replacement FAQ

Repair-vs-replace, lifespan, sizing, A2L refrigerant, cost, and financing.

What does HVAC replacement include?
A full replacement includes removing the old equipment and installing a new, load-calculated AC, furnace, or heat pump with matched indoor and outdoor units, new or reworked refrigerant lines and connections as needed, a compatible thermostat, startup and commissioning, and the permit. We also check the ductwork and correct problems so the new system actually performs. You get it all in one written, itemized scope.
How many years should an HVAC system last?
With regular maintenance, a central air conditioner typically lasts 15 to 20 years, a gas furnace 15 to 20 years, and a heat pump about 10 to 15 because it runs in both seasons. Sacramento’s hot summers work AC and heat pumps hard, so units here often land on the shorter end. Skipped maintenance shortens all of them, which is why condition matters as much as age.
Is it cheaper to repair or replace HVAC?
A single repair is cheaper in the moment, but the $5,000 rule, multiply the equipment’s age in years by the repair cost, helps decide: over $5,000 usually favors replacement. Efficiency gains, refrigerant type, and reliability also weigh in. We lay out the numbers so you can choose without pressure.
What to know before replacing an HVAC system?
Insist on a Manual J load calculation rather than just matching the old size, understand current SEER2 and AFUE efficiency and the new A2L refrigerants, have the ductwork evaluated, ask about financing and utility rebates, and get an itemized written quote. Right-sizing and install quality matter more than the brand on the box.
What questions to ask when replacing an HVAC system?
Ask whether the system is sized by a load calculation, whether the quote is written and itemized, who pulls the permit, what the warranty covers, whether the equipment is A2L-ready, whether ductwork is included, and what financing or rebates apply. Clear answers to these separate a professional install from a risky one.
What is better, 13 SEER or 16 SEER?
A higher SEER is more efficient and cheaper to run, so 16 beats 13 on operating cost. Note that ratings are now measured as SEER2, and California’s minimum for new split ACs is about 14.3 SEER2, so a true 13 SEER unit no longer meets code here. A higher-efficiency system costs more up front but lowers bills, and we help you weigh the payback.
Is it cheaper to replace a furnace and AC unit at the same time?
Usually yes, if both are near the end of their life. Doing them together means one install, properly matched components, better overall efficiency, and no second labor charge or refrigerant-compatibility headache down the road. If only one truly needs replacing, we’ll tell you that honestly rather than sell you both.
When should an HVAC be replaced and not repaired?
Replace rather than repair when the system is past roughly 12 to 15 years and facing a major repair, when bills are climbing, when breakdowns are frequent, when it still uses phased-out R-22 refrigerant, or when there’s a cracked heat exchanger. The $5,000 rule, age times repair cost over $5,000, is the quick test, and we walk through it with you.
Will HVAC prices go down in 2026?
It’s unlikely they’ll drop. The move to A2L refrigerants and higher SEER2 efficiency standards added cost to new equipment, and prices generally trend upward over time. Utility rebates can offset part of it, and planning a replacement before a breakdown gives you the best pricing and options rather than an emergency premium.
Is there a tax credit for a new HVAC system in 2026?
The federal 25C Energy Efficient Home Improvement Credit expired at the end of 2025, so there is no federal HVAC tax credit for new installs in 2026. Instead, look to state and utility rebates such as PG&E, SMUD, and TECH Clean California, which can be significant on high-efficiency heat pumps. We help you find and document what applies, and you confirm current programs with your tax professional.
Can I get a free HVAC system from the government?
There’s no blanket free-HVAC program, but income-qualified households may access weatherization and energy-assistance programs plus utility rebates that substantially cut, or in some cases cover, the cost of a high-efficiency system. Eligibility and funding vary and change over time. We can point you to the programs that may apply and provide the documentation you’ll need.
Is there HVAC system replacement financing available?
Yes. We offer financing options so a planned or unexpected replacement doesn’t have to be paid all at once, and we go over the available plans alongside the written quote. That lets you weigh a monthly payment against the energy savings of a higher-efficiency system. There’s no obligation, and we never rush the decision.
How much does HVAC system replacement cost for a 2000 sq ft house?
It depends on the equipment type, efficiency, and whether the ductwork needs work, so we quote each project after a load calculation rather than post a blanket figure. A straightforward same-size AC or furnace change-out is more predictable than a full system with new ducts or a switch to a heat pump. You always get the complete installed price in writing before you decide.
Is it cheaper to run a 110 or 220 mini split?
For the same cooling capacity, the operating cost is essentially the same, because your bill is driven by watts of energy used, not by voltage. A 220-volt unit simply draws less current for a given power and is common at higher capacities. What really determines running cost is the system’s SEER2 and HSPF2 efficiency and correct sizing, not 110 versus 220.
