Ductwork & Home Energy Optimization in Turlock, CA and the Central Valley

Don't Let Your Energy Use Go to Waste

If some rooms never get comfortable and your energy bill keeps climbing, the problem usually isn’t your air conditioner. It’s the ductwork and the envelope around it. ENERGY STAR estimates a typical home loses 20 to 30 percent of the air moving through its ducts to leaks, holes, and bad connections. Wally Falke’s finds where your home is wasting energy and fixes it at the source, with duct repair, duct replacement, insulation, and air sealing backed by our Triple Trust Guarantee. Proudly serving Turlock, Modesto, Merced, Manteca, and the surrounding areas.

Paying to Cool the Attic?

Leaky ducts and thin insulation usually show up as rooms that never match the thermostat, dust that comes back fast, and a bill that creeps up while your system runs longer and longer. If any of these sound familiar, your home is probably losing conditioned air before it ever reaches you:

  • One or two rooms are always hotter or colder than the rest of the house
  • The system runs and runs but the far rooms never reach the set temperature
  • Energy bills climbing with no change in how you use the system
  • Excess dust that keeps coming back soon after you clean
  • Weak airflow at the registers farthest from the unit
  • Rooms that feel stuffy or closed off from the rest of the house
  • A home built before the 1990s that has never had its ducts or insulation checked
  • Whistling or a rush of air around ceiling registers when the system kicks on

Duct Repair, Replacement, and Home Energy Services in the Central Valley

We start by finding where the loss is happening, then fix it at the source instead of oversizing a new system to fight a leak. Here’s what we do:

  • Duct repair & sealing — We seal leaking joints with mastic and metal-backed tape, reconnect fallen runs, and repair any torn or crushed sections. Sealing recovers much of the 20 to 30 percent that ENERGY STAR says a typical home loses through its ducts.
  • Duct replacement & new duct installation — When ductwork is undersized, poorly routed, or too far gone to seal, we design and install a new system sized for your home, right-sizing the return-air and supply runs so every room gets the airflow it’s supposed to. A bigger AC can never make up for undersized returns and a poor layout that never matched the house. We install sheet-metal and insulated flex ductwork and redesign return-air pathways, matching the material and layout to your home.
  • Attic & blow-in insulation — Central Valley heat pours in through an under-insulated attic. We add blow-in insulation (cellulose or fiberglass) to bring your attic up to the R-38 to R-49 range ENERGY STAR recommends for our climate.
  • Air sealing & weatherization — Small gaps around ducts, ceiling penetrations, and the building envelope let unconditioned attic and outside air into your living space. Sealing them cuts the raw, unfiltered air pulled through your home and takes load off the system. ENERGY STAR estimates air sealing plus insulation saves the average home about 15 percent on heating and cooling.
  • Blower-door & duct-leakage (HERS) testing — We measure exactly how much your home and ducts leak, so the plan is based on your house, not a guess. This is also the code-required testing California puts on system changeouts, and we handle it with certified HERS verification.

Our technicians also provide air duct cleaning, heat pump installation, smart thermostat installation, and other energy-saving services.

What Does Ductwork and Home Energy Work Cost?

Every home is different, so we quote ductwork and insulation per home after we’ve seen it, and we give you one up-front number with no bait-and-switch. The cost depends on what the assessment finds: a handful of sealed joints and a few reconnected runs is a small job, while a full duct replacement sized and routed for a two-story home is a larger one. Attic insulation is priced by square footage and how much R-value you need to add. Blower-door and duct-leakage testing is a defined-scope service we can quote on its own or roll into a larger project.

We start with a free in-home assessment so you know exactly what’s driving the cost before you decide anything. And because we’re the only Central Valley contractor to back our work with the Triple Trust Guarantee on parts, labor, and workmanship, the quote you approve is the work you get.

Rebates & incentives note: California offers utility and state incentives for duct sealing and insulation through programs like PG&E and Energy Upgrade California. Programs and eligibility change, so we’ll tell you which ones your project may qualify for at the time of your assessment rather than promise a specific dollar amount.

Ductwork Built for Central Valley Homes and Weather

Central Valley homes lose energy in ways a generic checklist misses. A lot of the housing stock in Modesto, Turlock, Ceres, and the surrounding towns was built between the 1960s and 1990s, and much of it still runs on its original ductwork: undersized, taped instead of sealed, and routed through attics that can hit 130 degrees and higher during the summer. When ducts leak up there, you’re cooling the attic and pulling that superheated air back into the system. In winter, the same leaks bleed the heat you’re paying for out through the roofline on cold, foggy Valley mornings. Add the ag dust that works its way into everything here, and older duct systems degrade faster than the equipment they feed.

Wally Falke’s has worked on these homes from our Turlock shop since 1969, so we know where to look. From Turlock we handle ductwork, insulation, and energy work across Modesto, Turlock, Merced, Manteca, Ceres, Oakdale, Ripon, Riverbank, Patterson, and Los Banos.

Ductwork & Home Energy FAQs

The usual signs are rooms that never reach the set temperature, hot and cold spots from room to room, dust that keeps coming back, weak airflow at the far registers, and an energy bill that climbs while the system runs longer. If you can see the ducts in your attic or crawlspace, look for torn insulation, crushed runs, and joints held together with old tape. A blower-door and duct-leakage test measures exactly how much is escaping so you’re not guessing.

It can make a real difference. ENERGY STAR estimates a typical home loses 20 to 30 percent of the air moving through its ducts to leaks and poor connections, and sealing recovers much of that. ENERGY STAR puts the savings from air sealing and adding insulation at around 15 percent of heating and cooling costs for the average home. Your result depends on how leaky the system was to start.

In most cases, yes. California’s Title 24 energy code requires HERS-verified duct-leakage testing when you install a new or replacement ducted system, or make major changes to the ductwork. New duct systems generally have to test at 5 percent leakage or less, and altered existing systems have to be brought down to about 10 percent. We handle the diagnostic testing and the verification as part of the job.

It depends on the shape and design of what you have. If the runs are sound and correctly sized, we seal the leaks and reconnect what’s come loose, which is the faster, less expensive fix. If the ductwork is undersized, badly routed, crushed, or too deteriorated to hold a seal (common in homes 30-plus years old), replacement is the fix that actually solves the comfort problem. We give you an honest recommendation either way.

A blower-door test measures how much air leaks through your home’s envelope, and a duct-leakage test measures how much escapes from the duct system specifically. Both produce accurate ratings, so the work we recommend is based on measurement instead of a hunch.

Often, yes, through utility and state programs like PG&E and Energy Upgrade California. Eligibility and amounts change over time, so we’ll tell you which programs your specific project may qualify for at your assessment rather than promise a number up front.
