HVAC questions, answered.

The most common culprits are a clogged air filter, a refrigerant leak, a failing capacitor or fan motor, a frozen evaporator coil, or ductwork losing cooled air before it reaches the rooms. A proper diagnosis pins down which one you actually have — guessing gets expensive.

It depends on the system's age, what failed, how often it's been failing, and how long you plan to stay in the home. A failed capacitor on a mid-life system usually points to repair; a failed compressor on an old, inefficient system is worth a replacement conversation. We diagnose first and lay out both paths.

We service standard residential split systems, package units, heat pumps, and ductless systems. When you call, tell us the brand and what the system is doing and we'll confirm before anyone rolls out.

If the system is frozen (ice on the lines or coil), switch it off so it can thaw — it can't be diagnosed frozen. Note anything you've observed: sounds, smells, breaker trips, and when the problem started.

An oversized AC short-cycles — it cools the air fast but never runs long enough to dehumidify or cool evenly, and the constant starting wears components. An undersized one runs continuously on hot valley afternoons and never catches up. Correct sizing comes from a load calculation on the actual home, not from matching whatever was there before.

Often, but not always. Ducts that are undersized, leaky, or poorly insulated will choke a brand-new system's performance. We evaluate the ductwork as part of the installation plan and tell you what it can support.

Equipment availability, the complexity of the electrical and refrigerant line runs, whether ductwork needs changes, and the local permit and inspection schedule. We give you a real timeline for your specific job when we quote it.

No. The right size beats a bigger size every time, and the right efficiency tier depends on how long you'll own the home and how hard your cooling season works the system. We'll show you the options and the honest trade-offs.

Weigh four things: the system's age, the cost and nature of the current failure, its repair history, and how long you'll stay in the home. Repeated failures on an aging, inefficient system usually mean money spent on repairs is money lost; a single fixable fault on a younger system usually isn't.

The main factors are system size (tonnage), the efficiency level you choose (SEER2 rating), the condition of your existing ductwork and electrical, installation complexity, and whether you're switching system types — for example, from AC plus furnace to a heat pump. We quote after seeing the actual home, not from a phone script.

SEER2 is the current federal efficiency rating for cooling equipment — higher numbers use less electricity for the same cooling. In the Sacramento region's long cooling season, efficiency differences show up on real utility bills, so it's worth weighing the efficiency tier against the upfront cost.

Yes — HVAC changeouts in California generally require a permit from your local building department, and California also has efficiency and installation requirements for new equipment. A licensed installation includes handling that process rather than skipping it.

Often, yes. A heat pump cools exactly like an AC and also heats your home efficiently in our mild-winter climate, replacing or supplementing a furnace. If your furnace is also aging, a heat pump can consolidate two future replacements into one decision.

Yes — a mini-split is a heat pump. The same system cools in summer and heats efficiently in winter, which suits the Sacramento region's climate of hot summers and mild winters particularly well.

Generally very. There are no duct losses because there are no ducts, and each zone conditions only the space it serves. Inverter-driven compressors also modulate instead of switching hard on and off.

One per zone you want to control independently. A single addition usually needs one head; a whole-home system might use several heads on one or two outdoor units. The right layout depends on the floor plan and how you use the rooms — that's part of the design visit.

Indoor heads are among the quietest HVAC equipment made — typically quieter than a refrigerator. The compressor sits outside, like a conventional AC but generally smaller and quieter.

Confirm the thermostat is set to heat and the setpoint is above room temperature; verify the furnace power switch (looks like a light switch) at or near the furnace is on; and check that the gas valve to the furnace is open. If all three check out and the furnace still won't start, that's a call for a technician.

Furnace repair is specific to combustion-based gas furnaces. Heating repair is the broader category — it covers heat pumps running in heating mode, dual-fuel systems that switch between a heat pump and furnace, and electric resistance heating. We land under whichever heading matches the equipment in your home.

On any gas-fired heating equipment visit we verify the heat exchanger is intact (no cracks or corrosion), the flue drafts properly, carbon-monoxide concentrations around the appliance are at safe levels, and the safety switches (limit, rollout, pressure) are functional. These checks are part of the call — not an upcharge.

Yes. Heat-pump heating faults are a different diagnostic category than furnace faults — reversing-valve logic, defrost cycles, and auxiliary-heat control — but we service all three heating equipment types (furnace, heat pump, dual-fuel) in Sacramento-region homes.

Common causes: the thermostat fan setting is on ON instead of AUTO (circulating unheated air), a failed ignition so the burners never light, an overheating furnace tripping its limit switch and running the blower to cool down, or a clogged filter starving airflow. Each has a different fix — diagnosis tells you which you have.

That's short cycling, and it's usually a safety system doing its job: overheating from a clogged filter or blocked airflow, a faulty flame sensor, or a venting problem. Repeated cycling wears parts fast, so it's worth diagnosing before it becomes a bigger failure.

It can be. A cracked heat exchanger or venting fault can allow combustion gases, including carbon monoxide, into the home. If your CO alarm sounds, leave the house and call your gas utility or 911 first. Working CO detectors are essential in any home with gas appliances.

Same logic as cooling: weigh age, the specific failure, repair history, and your plans for the home. In our region it's also worth asking whether a heat pump should replace the furnace entirely when it reaches end of life — we'll walk you through both paths.

The right answer comes from a load calculation, not a square-footage rule of thumb. We measure the home's actual heat loss based on insulation, windows, orientation, and duct losses — then size the furnace to match. Oversized furnaces short-cycle and feel drafty; undersized ones never catch up.

A 90%+ AFUE condensing furnace burns less gas for the same heat and needs a condensate drain plus different venting than an 80% model. The gas-cost savings add up over the furnace's life; the upfront cost is higher. We lay out the real trade-off, including venting constraints in your specific house.

Usually yes, as long as the coil and refrigerant lines are in good shape and the new furnace's blower is matched to the existing coil and ductwork. We check compatibility before quoting the install — not after.

California Title 24 requires a mechanical permit for a furnace changeout or new install. Permits are pulled from the local building department (city or county), and the installed system is subject to inspection. We handle the paperwork and the inspection appointment.

Cracked heat exchangers, repeated safety-switch lockouts, failed draft inducers on 15-plus-year-old units, and corroded combustion chambers are common replacement triggers. A single capacitor or ignitor failure on a 10-year-old furnace usually points the other way. We tell you which bucket your unit is in.

In the Sacramento climate, a cold-climate heat pump often makes sense as a furnace replacement — one system heats and cools, and the mild winters are well within modern heat pumps' efficient operating range. We walk through both paths with real trade-offs, including gas vs. electric utility costs and what your existing ductwork can support.

Most straight residential furnace replacements take one day of install plus permit and inspection follow-up. Venting changes, ductwork modifications, or combo installs with a new coil add time — we scope this honestly up front, not mid-job.

Yes. Removal, haul-away, and refrigerant recovery (when a coil is involved) are included — the old unit does not become your disposal problem.

Yes. Modern heat pumps heat efficiently well below the Sacramento region's typical winter lows. Our mild winters are the easy case — this area is one of the better climates in the country for heat pump heating.

A furnace burns gas to make heat; a heat pump moves heat with electricity, typically delivering two to four units of heat per unit of electricity. Which costs less to run depends on gas and electric rates and your home's insulation — we'll talk through the real trade-offs rather than a slogan.

Yes — that's the usual configuration: one outdoor unit and one indoor air handler replace both. If you want to keep the furnace, a dual-fuel setup uses the heat pump most of the time and the furnace only on the coldest mornings.

Incentive programs for heat pumps exist at federal, state, and utility levels, but they change and have eligibility rules. We don't quote incentive numbers here because they go stale — ask when you talk to us and check current program terms directly.

That symptom points directly at the reversing valve or its control circuit — the component that lets a heat pump run both directions. It can stick mechanically, lose its solenoid, or have a wiring fault. A technician diagnoses which failure mode and whether it's a repair or needs the valve replaced.

Normal heat pumps form some frost in heating mode and run a periodic defrost cycle to shed it. Heavy or persistent icing points at a defrost sensor, defrost control board, outdoor fan, or low-charge issue. Running the system covered in ice damages the compressor, so switch to auxiliary heat and get it diagnosed.

The individual components aren't dramatically different, but a heat pump has more of them — the reversing valve and defrost control have no counterpart on a straight AC. Diagnosis takes a technician familiar with heat pump logic; a shop that only repairs ACs will often misdiagnose the problem.

The same four factors as any HVAC repair-or-replace: age, nature of the failure, repair history, and how long you plan to stay. A failed capacitor on a seven-year-old system is a clear repair; a failed compressor on a fifteen-year-old system is almost always a replacement conversation.

R-22 was phased out in 2020, so new charges are expensive and increasingly limited. When an R-22 system develops a refrigerant leak or compressor issue, the economics typically point toward full replacement with a modern R-410A or R-454B system rather than chasing R-22 repairs.

Sometimes. If the existing line set is the right diameter, in good condition, and free of oil contamination from the old refrigerant, it can often be reused with proper flushing. On older or mismatched installs, replacing the line set is the honest answer — and we tell you which case you're in before quoting.

Inverter (variable-speed) heat pumps modulate output to match the home's actual load, which translates to better humidity control, quieter operation, and often lower utility bills — at a higher upfront cost. We lay out the real payback math for your specific home instead of defaulting to the premium option.

Yes. California Title 24 requires a mechanical permit for a heat pump changeout, with city or county inspection. We handle the permit and the inspection — the install is not finished until it passes.

Commercial equipment is usually larger, often on the roof, almost always belt-driven on the blower side, and more likely to include economizers and multi-stage controls. Diagnosis uses the same first-principles approach but the components, access, and safety requirements are different. Property managers also need documentation residential customers rarely ask for.

We service light-commercial package units and split systems commonly found on offices, retail, strip-center tenants, and smaller multi-tenant buildings. Industrial-scale chillers, cooling towers, and VAV systems are a different specialty and we'll tell you honestly when something is outside what we're the right call for.

Either works. For managed properties we route the ticket through the manager so documentation and billing match their process; for direct tenants or owner-occupied businesses we handle the whole engagement directly. We confirm the contact and billing path on the first call.

Yes. Every commercial visit produces a written summary of what was found, what was done, parts installed, and any recommended follow-up — the kind of record property managers need for maintenance files and that owners want for building operations history.

The old unit may have been oversized at install, the building use may have changed (fewer or more occupants, added computers, altered partitions), and current efficiency equipment often does more per nominal ton than older units. A load calculation sizes the replacement to the actual building, not an assumption that twenty-year-old sizing is still right.

A rooftop changeout typically needs: crane time scheduled, a curb adapter if footprints differ, updated electrical disconnect if required, a new condensate route if required, Title 24 compliance paperwork, and a permit from the local building department. We coordinate all of it in the scope rather than handing pieces to the owner.

A straight package-unit changeout on a single zone can often be done in a working day plus crane time. More involved projects — multi-unit buildings, changes in equipment type, duct modifications — are quoted with a schedule as part of the scope. We don't quote by phone; a commercial scope needs an on-site evaluation.

Yes — on retail and office properties, we commonly schedule work for off-hours or weekends so the business doesn't lose operating days. Phased replacements across multiple units on the same building are coordinated so the space never loses conditioning entirely.
