Real ductwork jobs · Kingfisher, Okarche and Oklahoma City

Ductwork replacement in Oklahoma: three real jobs, and why I say fall is the time to do yours

If you are going to do something about your ductwork, do it this fall. It is the easiest window of the whole year: your system is not fighting a hundred degree afternoon or carrying you through a hard freeze, so the day the duct is open is a day you barely notice. Below are three real duct jobs my crews did in Kingfisher, Okarche and Oklahoma City, each with a short video of what they found and what they did about it.

Juan and a second tech did the Kingfisher attic. Carl and the guys did the Okarche crawlspace. My crew did the Oklahoma City building, and I pulled the permits on that one. I stand behind all three.

Why fall is the window for ductwork and a new system

Why fall is the window for duct work, and why the duct comes first or at the same time as a high efficiency system.

Fall is the easiest window of the whole year for duct work. Your system is not fighting a hundred degree afternoon, and it is not carrying you through a hard freeze either, so the day the duct is open is a day you barely notice. My schedule has room in it that July and January simply do not have.

Thinking about a high efficiency system? The duct comes first.

If you are thinking about a high efficiency system, the duct comes first, or at least at the same time. A better furnace or heat pump still has to push its air through whatever is up in that attic. Put good equipment on leaking, undersized duct and you paid for efficiency you will never get to use. Do them together and the whole house works.

Call 405-375-4822 and I will come look at what you have. The estimate on a new system or a full duct replacement is free.

Three real duct jobs from this year

An attic in Kingfisher, a crawlspace in Okarche and a commercial building in Oklahoma City. Each one has a short video and photos from the job. Town level only: I do not publish customer names or addresses. For more jobs by town, see my work across central Oklahoma.

Kingfisher · attic duct sealing and support

Kingfisher: the duct was pulling air out of the attic

Kingfisher attic: sealed with mastic and UL-181 tape, supported, and brought up to code.

The duct in this house was pulling air out of the attic instead of out of the home, and in an Oklahoma August the attic is the hottest air on the whole property. Juan and a second tech went through it. They sealed every connection, joint and collar they could get to with mastic and UL-181 tape, put real support under the runs, and brought the system up to code.

“The system is now pulling air from your home, not the attic.”

Juan, writing up the Kingfisher job. He said it better than I would have.

If you have a room that never keeps up, the duct is one of the first places I look. More on that kind of work: air duct sealing in Oklahoma.

Okarche · crawlspace flex duct replacement

Okarche: flex duct in the dirt, replaced with hard pipe

Okarche crawlspace: sagging, torn flex duct out, insulated hard pipe sheet metal in.

This is what the duct under this house in Okarche looked like: flex duct sagging between the joists, laying in the dirt, torn open in places. Every one of those sags is a spot where the air slows down and gives up its heat before it ever reaches the room. Every tear is air you already paid for going straight into the ground.

So my crew pulled all of it out. Carl and the guys fabricated hard pipe sheet metal, ran it through the house, wrapped the whole thing in duct insulation, and set ten new floor supply grilles. Hard pipe does not sag in ten years.

If you have never been under your own house, that is where I would look first. More on this kind of work: air duct repair in Oklahoma and custom sheet metal and ductwork fabrication.

The photos below show the old duct, the condition that called for the replacement. They are not the finished hard pipe.

Oklahoma City · commercial building, new duct

Oklahoma City: new duct up in the steel of a commercial building

Oklahoma City commercial building: new supply and return duct up in the steel, permitted and done to code.

This one is a commercial building in Oklahoma City, back in June. The package unit was already sitting on the roof. What the building needed was the duct underneath it, so my crew put in the supply and return, up in the steel where nobody ever looks.

They set a proper roof jack, cap and collar where the vent goes through the roof, so it stays sealed against the weather, and ran a six inch bathroom exhaust out through the roof. I pulled the city permits and it was done to code.

Nobody who walks into that building will ever notice that duct, and that is fine. It is the part that decides whether the unit on the roof can do its job at all. More on my commercial work: commercial HVAC in central Oklahoma and strip center and retail HVAC.

What it costs to find out what your duct is doing

I do not quote duct replacement or duct sealing over the phone. What is in your attic or under your floor decides that, so I come look first. Here is what each kind of visit costs.

A room that never keeps up

$210 flat

Residential service call: $99 dispatch plus $111 diagnostic. The diagnostic is not credited toward the repair. This is the visit when a room never keeps up or the system cannot keep the house comfortable.

A new system or a full duct replacement

Free estimate

If you are planning a new system or a full duct replacement, the estimate is free. I need to see what you have before I put a number on it.

A commercial building

$389 flat

Commercial diagnostic, day or night, for light commercial up to 15 tons. Larger systems are sized on site.

Paying for it

Financing

Financing covers duct work and repairs, not just new systems. I work with Synchrony (up to 18 months 0%), Wells Fargo, Wisetack, Klarna and JB Financing.

Questions I get about ductwork in Oklahoma

When is the best time to replace ductwork in Oklahoma?

Fall. Your system is not fighting a hundred degree afternoon and it is not carrying you through a hard freeze either, so the day the duct is open is a day you barely notice. My schedule also has room in the fall that July and January simply do not have. Call 405-375-4822 and I will come look at what you have.

Should I replace my ductwork when I put in a high efficiency system?

The duct comes first, or at least at the same time as the new system. A better furnace or heat pump still has to push its air through whatever is up in that attic. Put good equipment on leaking, undersized duct and you paid for efficiency you will never get to use. Do them together and the whole house works. The estimate on a new system or a full duct replacement is free. Call 405-375-4822.

How much does it cost to have my ductwork checked in Kingfisher Oklahoma?

If a room never keeps up or the system cannot keep the house comfortable, it is a $210 flat residential service call: $99 dispatch plus $111 diagnostic. The diagnostic is not credited toward the repair. If you are planning a new system or a full duct replacement, the estimate is free. Call 405-375-4822.

Is flex duct or hard pipe better under a house?

Under a house I want hard pipe. On the Okarche job the flex duct was sagging between the joists, laying in the dirt and torn open in places. Every sag is a spot where the air slows down and gives up its heat before it ever reaches the room, and every tear is air you already paid for going straight into the ground. My crew pulled all of it out and put in hard pipe sheet metal wrapped in duct insulation. Hard pipe does not sag in ten years.

Do you do commercial ductwork in Oklahoma City?

Yes. In June my crew put new supply and return duct into a commercial building in Oklahoma City, up in the steel under the package unit on the roof, with a proper roof jack, cap and collar where the vent goes through the roof. I pulled the city permits and it was done to code. A commercial diagnostic is $389 flat, day or night, for light commercial up to 15 tons, and larger systems are sized on site. Oklahoma County is one of the seven counties I service every day.

Do you service my town?

I service seven counties every day: Kingfisher, Canadian, Oklahoma, Garfield, Major, Logan and Blaine. If your town is in one of them, call 405-375-4822 and I will come look at what you have. Outside those seven counties I do not cover duct work.

Want me to look at your duct this fall?

Call 405-375-4822 and I will come look at what you have. A room that never keeps up is the $210 service call. Duct replacement or a new system, in Kingfisher, Okarche, Oklahoma City or anywhere in my seven counties, starts with a free estimate.
