Estimating commercial air duct cleaning projects is different from estimating and prices residential projects. You cannot count the amount of vents or pass the square footage of the building to estimate industrial projects. There is definitely such a multitude of HVAC system types a simple one size fit all estimating approach won't work.

A workable estimating program/process must be in a position to handle the wide selection of HVAC systems and parts found in today's commercial structures. Plus, you'll want a good understanding of the various elements that you will encounter because each of these elements can present their own unique cleaning challenges. Your objective is with an accurate and repeatable estimating procedure so that you can win even more projects on a consistent basis. Let's look at the basic steps:

1. Review and understand the cleaning specification.

Most commercial projects have a cleaning specification that lets you know what needs to be cleaned, the amount of cleanliness that must be accomplished, documentation requirements, etc. Washing specifications are determined by localbusinesslisting.org/benzvac-llc the project engineer or environmental consultant. The National Air Duct Cleaners Association (NADCA) cleaning specification may be the basis for many of the specifications.

You must read and understand the cleaning specification if you are going to make a proper proposal. For those who have queries on a washing specification make sure to contact the engineer for clarification. If there is no cleaning specification https://www.washingtonpost.com/newssearch/?query=air duct cleaning you can help the building owner by giving one. The cleaning specification that you give fireplace and chimney cleaning Bergen County will include items and requirements that may favor your companies' features and give you a bidding benefit.

2. Review and understand the mechanical blueprints.

Get a set of blueprints for the task. You will have to know how to browse blueprints. Large tasks can have many pages of blueprints which can be extremely challenging. The best way to approach something like that is to check out one air flow handler and its associated ductwork at the same time. The mechanical prints can also have important information about the scope of the surroundings duct cleaning requirements and a timetable of units. All of this information is very important because it http://edition.cnn.com/search/?text=air duct cleaning allows you to understand the HVAC program you are estimating.

3. Execute a walk through of the task.

This will help you understand the project and let you see whatever will affect accessibility to the cleaning of the HVAC system. Option of the HVAC program and components will help determine the production rate you will use. Good accessibility generally means a faster production rate and poor accessibility means a slower production rate.

4. Do a takeoff of the HVAC program.

After you have looked at and gained a good knowledge commercial air duct cleaning Emerson NJ of the mechanical blueprints and also have done place123.net/place/benzvac-llc-boonton-usa a walk through of the project you are ready to start focusing on your estimate. Based on the blueprints, you break down the HVAC system into its component parts and find the number of each component you have. For example:

• number of air handlers

• linear feet of source duct work

• linear feet of come back ductwork

• number of grills and registers

• number of VAV boxes

• number of coils

• etc.

It is very helpful to use different color markers to color in the various components on the http://query.nytimes.com/search/sitesearch/?action=click&conten... blueprint. After that it is much easier to count the amount of each element and enter that number on your remove sheet. Also, you are less inclined to miss something if you are coloring in each component.

5. Determining the amount of man hours required.

Once the remove is complete, you determine the amount of man hours had a need to clean each component. For example:

• 2 air chimney cleaning handlers at 6 guy hours each = 12 man hours

• 500 linear foot of ductwork at 15 feet per man hour = 33 guy hours, etc.

You then add all of the man hours for every element to get the full total man hours for the task.

6. Identifying the charge per man hour

Once you have determined your total guy hours needed to complete the project you apply the labor rate that you will charge your customer. For example: should you have a total of 100 man hours on the project at $75.00 per man hour labor price = $7,500 labor estimate. You will have to charge at least $75.00 per man hour to possess gross earnings that ranges from 40% to 60%. Some places charge more and some charge less. You might have to do a little research in your area to decide what a competitive labor price will be.

7. Determining consumables source charges

Next, you determine your consumable supply cost. These are the costs for things like duct tape, poly, etc. Take 5% to 7% of your labor estimate to cover these consumable items. If your project takes a coatings or sanitizers or relining of surroundings handlers you should have a line item estimate for covering, the sanitizer and the closed cell insulation. Many contractors consider the cost of these things and mark them up 10-20%.

8. Determining additional miscellaneous charges.

If you need to rent equipment like a lift or airless sprayer, have any travel costs you will have to add these things also. Every one of these will be a separate series item on your estimate sheet. Also some contractors charge for the set-up and take down time on the project.

Summary

You now will finish up with an estimate of the following items:

• Labor estimate
