Getting an HVAC bid right is hard. One wrong number on a duct run or a missing air handling unit can affect your budget or you can lose the job. You need a partner who knows HVAC inside and out. Not a general estimator. Someone who understands ductwork, equipment sizing, and system coordination. ALM estimating offers HVAC estimating services that focus on the details that matter. We provide accurate ductwork. Equipment and system coordination. No guesswork. Just clear, accurate takeoffs to help you bid with confidence.

HVAC estimating services means counting everything that goes into a heating, ventilation, and air conditioning system. This includes materials, equipment, and the labor to install it all. HVAC estimating covers quantities for every piece of duct, every diffuser, every boiler, and every air handling unit. This helps you know exactly what to buy and how much to charge.
Our HVAC cost estimating services are built for contractors who need real numbers, not rough guesses. We cover commercial, residential, and industrial projects.
Our HVAC bid estimating covers all project types. We have experience across the board.

HVAC systems are expensive. A small mistake in equipment sizing or ductwork can cost thousands. Here is why accuracy is not optional.
One chiller or boiler costs more than many other trades combined. You cannot afford to guess.
When your quantities are wrong, you order the wrong parts. Then jobs slow down. Change orders pile up. Profits disappear.
Ductwork must fit with pipes, beams, and electrical runs. A good estimate catches conflicts early.
A tight, accurate bid wins more jobs. You price the real scope, not a padded guess.
In short, accurate HVAC system costing helps you reduce risk, improve efficiency, and enhance project accuracy.
When you hire us for HVAC takeoff services, you get a complete breakdown. Here is exactly what we include.
Ducts are the backbone of any HVAC system. We provide detailed ductwork estimation including:
Supply ductwork (linear feet by size and gauge)
Return ductwork
Exhaust ductwork
Duct fittings (elbows, transitions, taps)
Duct insulation (type and thickness)
Hangers and supports
We measure everything directly from your drawings. You will know exactly how much sheet metal to order and how many labor hours to budget.
HVAC equipment is expensive. A single chiller or boiler can cost tens of thousands of dollars. Our HVAC quantity takeoff includes:
Air handling units (AHU): Count, size, and configuration
Chillers and boilers: Capacity and quantity
Rooftop units (RTU): Tons and quantity
VRF systems: Outdoor units, indoor units, and branch controllers
Heat pumps and furnaces
VAV boxes and terminal units
Ventilation is critical for indoor air quality. We estimate:
Diffusers and grills (supply, return, exhaust)
Dampers (manual, motorized, fire, smoke)
Louvers and hoods
Ventilation ductwork for fresh air and exhaust
Many HVAC systems use chilled water or hot water. We estimate:
HVAC piping by material (steel, copper, CPVC) and diameter
Fittings and valves (ball valves, butterfly valves, control valves)
Pipe insulation (thickness and type)
Pumps and accessories
Material is only half the picture. We estimate labor hours for:
Duct fabrication and installation
Equipment setting and connection
Piping installation
Insulation application
System startup and testing
We do not just count equipment. We also estimate rigging, setting, and hookup labor.
We use current SMACNA productivity standards and adjust for your project location. You get real numbers, not national averages.
We follow a simple, clear process for every estimate. You always know where your project stands.
Our experts look at your plans, specs, and addenda. We flag anything unclear before we start.
We break down the project by system: heating, cooling, ventilation, and controls.
Our experienced estimators measure every duct, every fitting, every unit. No bulk counting. Item by item.
We apply current material pricing and local labor rates. No national averages.
You receive a clear Excel file with quantities, costs, and marked-up drawings. Ready to bid.
Here is a real example from a recent commercial HVAC estimate. This shows the level of detail you can expect.
For most commercial HVAC projects, costs break down like this. This helps you understand where your money goes.
Equipment (AHUs, chillers, boilers, RTUs): 40-50%
Ductwork materials and fabrication: 20-25%
Installation labor: 20-25%
Controls, insulation, and accessories: 10-15%
This breakdown targets common cost-related searches and gives you real value. You can use it to check your own bids or explain pricing to clients.

Get a second set of eyes on complex system estimates.
Verify HVAC bids from subs before you present to the owner.
Get early budget numbers for HVAC systems before design is final.
We include ductwork, equipment (air handling units, chillers, boilers, rooftop units), ventilation components (diffusers, grills, dampers), HVAC piping, and labor. You get a complete system breakdown.
We need your HVAC plans, mechanical drawings, specifications, and any addenda. Equipment schedules and control diagrams help but are not required.
Our estimates are typically within 2-3% of final bid numbers. We count every item individually and double-check all quantities. A second estimator reviews every takeoff.
Most residential and light commercial estimates take 24-48 hours. Large commercial or industrial projects may take 3-5 business days. We confirm the timing when you send your drawings.
Yes. Our estimates show separate totals for equipment, ductwork, piping, controls, and labor. You get full transparency.
You receive an editable Excel file with takeoff sheets, a summary tab, and marked-up PDF drawings. Ready to use for bidding or client presentation.
