Sealed, balanced and code-correct ductwork for every room
Furnace Ductwork Loveland CO Built to Move Heat
Furnace Ductwork Loveland CO work starts with a simple question: is the heat your furnace makes actually reaching your rooms? We pressure-test, seal, repair and rebalance ductwork and venting in Loveland, Colorado for homes from Downtown to Boyd Lake. If one bedroom runs cold while the thermostat says 70, the duct system is the problem, not the furnace.

What's included
What Our Ductwork Service Covers
Every ductwork visit includes a full airflow test, a camera inspection of the supply and return runs, and a written report with before-and-after numbers. Sealing, boot repair and damper balancing are part of the standard job. Full trunk replacement, new flue pipe and insulation upgrades are quoted separately once we see the scope.
Static Pressure Testing
We drill a test port in the plenum and read static pressure with a manometer, then compare it to the equipment data plate. High readings tell us the ducts are restricted. This single measurement drives everything else we recommend.
Camera Duct Inspection
An inspection camera runs the trunk and branch lines so we can see disconnected boots, crushed flex, rodent damage and unsealed joints. You see the footage, and we note every problem on the report with a location.
Joint Sealing and Boot Repair
We seal joints with duct sealant and mastic rather than tape alone, then screw and reseal boots that were hanging loose. Sealing is where most of the efficiency gain comes from, and it is included in the standard price.
Flue and Venting Check
We inspect flue pipes for correct slope, secure joints and proper termination, then verify draft with a combustion analyzer on gas systems. Venting problems get corrected on the same visit whenever parts allow.
Damper Balancing
Once the leaks are sealed, we set the dampers so each room gets its share of airflow. We verify with a thermometer at every register and adjust until the spread across rooms is within a few degrees.
Filter and Airflow Handoff
We install a correctly sized furnace filter and tell you the MERV rating to buy next time. You also get the written airflow report showing static pressure and room temperatures before and after the work.
Service overview
Furnace Ductwork Loveland CO: What We Actually Do
Furnace Ductwork Loveland CO is the supply and return air side of your heating system: the trunk lines, branch runs, boots, dampers, plenum connections and the flue pipe that carries combustion gases out of the house. We inspect every joint with an inspection camera, measure static pressure with a manometer, and find the leaks, crushed runs and disconnected boots that bleed heat into crawlspaces and attics. Then we seal, repair or rebuild them so the air your furnace pays to heat lands in living space.
Most Loveland homes we open up were built between the 1970s and the 2000s, and the ductwork shows it. Flex runs pinched behind drywall, taped joints that dried out years ago, and flue pipes pitched wrong on a 90-degree July day. When a homeowner calls about a furnace blowing cold air or a bedroom that never warms up, ductwork and venting in Loveland, Colorado is usually where the money is going. We also handle furnace duct repair Loveland CO jobs after remodels, where a new wall cut a return in half.
How we workWe verify the cause, compare realistic options, and confirm the repair before we leave.
The service timeline
How Our Ductwork Service Runs
The process flexes to the condition, but these checkpoints keep decisions clear.
Airflow Test
We start at the furnace, drilling a small test port in the plenum and reading static pressure with a manometer. Then we check temperature rise against the data plate and walk every register with a thermometer. That takes 30 to 45 minutes and tells us whether the problem is supply, return or both.
Camera Inspection
An inspection camera goes down the trunk lines and branch runs. We look for disconnected boots, crushed flex, rodent damage, and joints that were never sealed. On the venting side we check flue pipe slope, joints and termination. You see the same footage we do.
Seal and Repair
We seal joints with duct sealant and mastic, not just foil tape, then reattach and screw boots that were hanging loose. Crushed runs get replaced with properly sized hard pipe or flex. Most single-family repairs take two to four hours; a full trunk rebuild can run a full day.
Balance and Verify
After sealing, we re-read static pressure and set the dampers so each room gets its share of airflow. We check flue draft with a combustion analyzer on gas systems and confirm the furnace is not short cycling. You get the before-and-after numbers in writing.
Filter and Handoff
We install a correctly sized furnace filter, show you the MERV rating to buy next time, and walk you through what we changed. If a blower motor or heat exchanger is also worn, we tell you now rather than after it fails in January.
Tools & methods
Tools and Standards We Work To
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
Manometer
Reads static pressure in the supply and return plenums. It tells us whether the duct system is restricted and by how much, before we touch a single joint.
Combustion Analyzer
Measures flue gas composition and draft on gas furnaces. We use it to confirm the vent is pulling combustion gases out of the home the way it should.
Inspection Camera
Goes inside trunk and branch runs to find disconnected boots, crushed flex and rodent damage that is invisible from the outside.
Thermometer
Checks supply air temperature at each register. It is how we verify that balancing actually evened out the rooms instead of just moving the problem.
Multimeter
Tests blower motor amp draw and control board voltages. High amp draw on a blower is often the first sign of restricted ductwork.
Vacuum Gauge
Confirms gas pressure at the valve on gas furnaces. Correct pressure keeps the burner running clean and the venting working as designed.
Fin Comb and Nut Driver Set
Straightens coil fins and opens equipment panels cleanly. Small tools, but they keep us from damaging components while we work.
Use cases
When Loveland Homes Need Ductwork Work
These examples show how the service framework adapts rather than forcing every call through one repair.
High Gas Bills in a Downtown Ranch
A 1978 ranch had original ductwork with taped joints that had dried out. Static pressure read well above the equipment spec, and the homeowner was ready to replace the furnace because the gas bill kept climbing. → We sealed every accessible joint with mastic, replaced three crushed flex runs and rebalanced the dampers. Static pressure dropped back into spec, and the next full-month gas bill was about 20 percent lower.
Flue Pitch Problem in Centerra
A property manager called after a tenant reported the pilot light going out repeatedly. The flue pipe on the unit was pitched backward, so condensate pooled in the pipe and draft was inconsistent. → We corrected the flue pitch, replaced the rusted section of pipe and verified draft with a combustion analyzer. The pilot stayed lit, and the unit passed a full venting check before the heating season.
Problems we solve
Ductwork Problems We Solve in Loveland
Most no-heat and uneven-heat calls we run in Loveland trace back to the air side, not the burner. Here are the four problems we see most, what happens if you leave them, and how we fix them.
Rooms that never reach the thermostat setting
We measure airflow at every register, find the crushed or disconnected run starving that room, and repair it. Then we balance the dampers so the whole house heats evenly. Most fixes take two to four hours.
Furnace short cycling and tripping on high limit
We read static pressure, identify whether the restriction is on the supply or return side, and open up the airflow. If the return is undersized, we add capacity. That stops the short cycling at the source.
Flue pipe pitched wrong or joints rusted through
We inspect the full flue run, correct the pitch, replace rusted sections and verify draft with a combustion analyzer. Every gas appliance we open gets a venting check before we leave.
Dust streaks and dirty air at the registers
We seal the leaking joints with mastic, reattach loose boots and confirm the return side is tight. Cleaner air at the register and a filter that lasts its full interval are the usual result.
Pricing process
What Ductwork Service Costs in Loveland
$400 - $3,500 depending on scope
Accessibility
Ductwork in a finished basement ceiling or a tight crawlspace takes longer to reach and seal. Easy attic access keeps the price down; a finished ceiling adds labor.
Extent of Damage
Sealing a few leaking joints is a short job. Replacing crushed flex runs, rebuilding a trunk section or reattaching disconnected boots adds material and time.
Number of Runs
A small ranch might have eight branch runs; a two-story with a bonus room can have twenty. More runs mean more joints to seal and more registers to balance.
Customer reviews
What Loveland Customers Say
★★★★★
“Our back bedroom never got above 63 all winter. The tech found a crushed flex run behind the drywall and a boot that was never sealed. He replaced the run, sealed the joints and balanced the dampers. The room hit 70 that same night. He showed me the static pressure readings before and after, which I appreciated.”
★★★★★
“We were ready to buy a new furnace because the gas bill was out of control. Loveland FurnaceRepair tested the ducts first and found leaks all over the attic trunk line. Sealing and insulating cost a fraction of a new furnace, and the next bill dropped by about $70. Honest work, no upsell.”
★★★★★
“We manage several rentals and had a flue pipe pitched wrong on one of them. Their tech caught it during a ductwork inspection, corrected the pitch and verified draft with a combustion analyzer. That could have been a serious safety issue. They documented everything and sent photos for our records.”
How much does Furnace Ductwork Loveland CO cost?
Most Loveland ductwork jobs run $400 to $900 for sealing and balancing, and $1,200 to $3,500 for a partial trunk rebuild. Typical 2026 pricing in this area depends on how many runs are damaged, whether the ducts sit in a crawlspace or attic, and how much flue pipe needs replacing. We give you the number before we start and it does not change.
How do I know if my ductwork needs repair in Loveland?
Three signs point to duct problems: rooms that never reach the thermostat setting, gas bills that climb while comfort drops, and visible dust streaks at the register boots. If your furnace blows cold air at the far end of the house while the plenum is hot, the ducts are losing the air. A static pressure test confirms it in under an hour.
Who offers ductwork and venting near me in Loveland CO?
Loveland FurnaceRepair handles both sides of the system, supply and return ducts plus furnace venting services Loveland homeowners need for safe flue operation. We cover Downtown Loveland, Centerra, Boyd Lake, Mariana Butte, Pinewood and the rest of Larimer County. One call books the inspection, the repair and the airflow verification.
Can furnace ductwork improve efficiency in Loveland?
Yes. Sealing and balancing ducts in a typical Loveland ranch recovers 20 to 30 percent of the air that was leaking into crawlspaces and attics. That means shorter furnace cycles, lower gas use and more even temperatures. On older homes it is often the highest-return efficiency work available, ahead of a furnace replacement.

Furnace Replacement
If your ducts are undersized for a new high-efficiency unit, replacing the furnace without fixing the air side wastes the upgrade. We size the new equipment against your existing duct capacity so the system performs the way the spec sheet promises.Furnace Maintenance & Tune-Ups
Annual tune-ups catch duct and venting problems before heating season. We check flue draft, blower amp draw and filter condition, then flag any ductwork issues while they are still cheap to fix. Most Loveland customers book in September or October.
Emergency Furnace Repair
When a furnace quits at 2 a.m. in January, a blocked or disconnected flue is sometimes the cause. Our emergency techs carry flue pipe and duct fittings so they can restore safe venting on the first visit instead of scheduling a return trip.Ready when you are
