Are you paying too much for your HVAC equipment? How do you know if the quote you received for your equipment is a fair price? Do you have a method of comparing what you have paid for various HVAC equipment with what is being quoted currently?
Keeping track of the cost of HVAC Equipment allows you to quickly provide budgets and check the cost of equipment before you purchase. This database allows you to easily keep track of the most common HVAC equipment.
HVAC Equipment Cost Database
Using an HVAC Equipment cost database will save you a lot of money by avoiding the costly mistake of paying too much for equipment.
Air Conditioners in Historical Pricing HVAC Equipment Database
The HVAC Equipment Cost database keeps track of all your equipment quotes or purchases for easy reference and parametric checks, such as cost per ton ($/Ton), cost per CFM ($/CFM)
For an HVAC Piping & Plumbing Estimator the need for quick budgets for the installation of piping is best handled with a matrix of different material types and sizes. Having an estimating software program can make this process a lot easier as the material pricing is always up to date and can be entered into the matrix quickly.
HVAC Piping Unit Pricing Calculator
UNIT PRICING
Often the requirements of the RFP or bidding instructions will call for the price per foot to install piping beyond that which is required by the contract drawings. Such pricing maybe used for change-orders. Having these numbers available and updated often also gives you a quick reference for budgeting projects. It’s good to know when doing job site comparisons of different piping options or during discussions with engineering, what the cost is for the various piping sizes and types of materials.
HVAC Piping Unit Pricing Calculator for Copper and Carbon Steel from 1/2″ to 14″
COST PER FOOT
The cost per foot for the installation of piping needs to include fittings and hangers prorated into the value. It’s best to look at a standard length of pipe and then figure that you will have a Tee and 90 degree elbow in that length. So for example, using twenty feet of copper water pipe with a Tee and 90 degree elbow plus the hangers to build a unit price would represent a field condition of a fitting every ten feet. For higher density projects like Hospitals you could put more fittings in your unit pricing. Total those cost up and then divide by 20 to derive at a cost per foot for that particular size and material type.
20 feet of pipe + 2 Fittings + 3 Hangers / 20 = Cost per Foot
If the piping is insulated, you can also put the values in for insulation.
The Estimating Wizard provides two spreadsheets for tracking unit pricing, one for HVAC Piping and the other for Plumbing piping. Get a copy and start tracking your cost per foot, or be prepared to give a quick budget based on your knowledge from your spreadsheet of unit prices. Watch the video on the estimating Wizard website and see how quick and easy it is to track the cost per foot for various sozes and material types.
MEP Academy HVAC Piping Unit Pricing Calculator
The MEP Academy provides a spreadsheet that makes calculating unit pricing simple. The spreadsheet is available on the MEP Academy website https://mepacademy.com
HVAC Piping Unit Pricing Calculator Example
In the screenshot above there is a place for you to build your hanger requirements (#1), and a place to put your tax rate and hourly labor rate (#2).
For each size of pipe and material type you would insert the unit cost for Material (#3) and Labor (#4).
Under item (#5) you would build your typical run of pipe and enter the quantity of fittings you might expect for the type of building and system. You would add whatever you think will be required for every so many feet of pipe. In the example above we are showing that for every 20 feet of pipe you will have 1 Elbow and 1 Reducing Tee.
Under item (#6) you would add the cost per lineal foot for insulation if required. You could also look at insulation as a separate value and leave the pipe bare.
Line item (#7) is where you indicate the hanger spacing, and for each hanger you defined under item (#1) you will get the quantity as defined by the linear feet in item (#5) divided by your hanger spacing, which will affect your cost.
Line item (#8) is the calculated cost per linear foot of piping for that size and material type of pipe.
Summary Sheet
After you have all your unit pricing information inputted into the spreadsheet, all you have to do to get a budget for installing piping is to enter the quantity of piping (#9) for each size and material type (#10). The system will automatically calculate the cost (#11) to install that run of piping based on your unit pricing data. The total cost will be shown at the top of the spreadsheet (#12).
The proper sizing and layout of condensate drain lines is important for the protection of property and for the proper functioning of the air conditioning equipment.
Condensate Drain Pipe Sizing
The size required for the condensate pipe is dictated by the local code. Enclosed you will find the requirements for many local codes, but be sure to check your code for your local requirements. If the outlet size of the equipment’s condensate drain is larger than what’s shown in this chart then your required to use the larger outlet size.
Minimum Condensate Drain Pipe Sizing Chart
Slope to be at least 1/8” per foot or 1 percent, that is for every 12” horizontally there must be at least an 1/8” drop vertically.
Condensate drain piping to slope a minimum of 1/8″ per every 12″ horizontal
Attics or Furred Spaces
If the Air Conditioner is suspended above an inaccessible ceiling, such as a gypsum board ceiling or attic space then you will need to provide a means for protecting the building elements from the overflow of the primary drain and for indicating that there is a leak.
Also, drain pans that are poorly drained can cause water to stay in the pan risking the possibility of algae and bacteria growth. Below are some possible solutions, but as always check your local code for the approved method.
Option 1 – Secondary drain pan with drain piping. This would hang below the Air Conditioning unit in case the A/C units primary pan overflowed. Also, there is a requirement to provide secondary drain piping to a point of termination that would provide notification to the occupants that there is a leak, such as terminating above a window or doorway.
Option 1 – Secondary drain pan with piping terminating in observable location
Option 2 – An additional drain pipe connection that sits above the primary drain connection and whereby the secondary drain piping terminates in a location to alert the occupants of the clogged primary drain.
Option 2 – Secondary drain piping connection to primary drain pan
Option 3 – Leak detection device that automatically shuts down the Air Conditioner if the primary drain becomes clogged.
Option 3 – Primary drain with leak detection device
Option 4 – Secondary drain pan with leak detection, located beneath the coil that shuts down the unit upon a leak.
Option 4 – Secondary drain pan with leak detection
The additional drain pan or drain pan connection shall be provided with a drain pipe that will determinate in an observable area, such as in front a window or above a doorway, and be of a size not less than 3/4”. Secondary drain pan shall not be less than 1-1/2” in height and extend 3” wider on each side of the coil or AC unit.
Secondary drain piping terminating above window. Pipe doesn’t have to be visible as shown.

Drain Termination
Where can and can’t you terminate the air conditioners condensate drain piping? There are several options where you can terminate the condensate drain line;
Indirect Drain
Condensate Pump to Indirect Drain
Drywell
Leach pits
Landscaped areas that are properly designed to handle the volume of condensate
To Properly designed stormwater treatment systems.
Indirect Drain
Lavatory tailpiece in the same tenant space as the air conditioner
Laundry standpipe
Janitors Sink
Inlet of Bathtub Overflow – Must be accessible
Collect and send to cooling tower (See description below)
Cooling Coil condensate to sink tailpiece.
The connection to a plumbing fixtures tailpiece has to be made within the same tenant space as the air conditioner cooling coil that is generating the condensate.
Drywell
A drywell can be used for the termination of your air conditioners condensate drain. Check your local code for the specifics, but generally it includes some or all of the following depending on whether it’s for residential or a commercial project:
A minimum size hole, such as 2 foot by 2 foot by 3 feet deep, or a round hole such as 12” diameter by 3 feet deep.
A minimum of 6” of soil or concrete shall provide cover above the rocks
Some form of barrier between the soil and the top of the drywell where the rock begins, such as building paper or plastic
Drywell to be filled with gravel or crushed rock, often with a stated minimum size rock such as 1 inch diameter
The termination of the condensate drain pipe shall connect indirectly to the drywell drain pipe.
The drywell drain pipe to be a minimum of 1-1/2” PVC or other approved material.
Drywell to be at least three feet away from the building structure or any footings.
Drywall for Air Conditioner Cooling Coil Condensate
There are various methods of providing drywells depending on the local code. There are prefabricated drywells that can be used and ones that are made by using a large diameter piece of PVC pipe or similar material.
Some codes will require you to collect the condensate from cooling coil drain pans and return it to the cooling tower if the equipment is served by a cooling tower and the total combined capacity of the HVAC cooling coils exceeds a certain amount like 65,000 btu/hr. This is a water conservation measure, and there are some exceptions to this requirement, such as if the total capacity of the AC Equipment cooling coils are less than 10% of the total capacity of the cooling tower, or if the location of those AC Cooling coils are in a remote location, far from the tower.
Some locations where you can’t terminate condensate;
Public ways
Sidewalks
Driveways
Alleys
No termination of condensate on public area ways
Excluded from Code Requirements
Excluded from these codes are non-condensing type of equipment like radiant cooling panels that are designed to prevent condensate from occurring by keeping the temperature of the chilled water above the dew point temperature/vapor pressure of the surrounding air. These are system designed to operate in sensible cooling only modes.
Piping Material
The material types that can be used for condensate drain piping varies by jurisdiction but the most commonly cited materials are:
Copper
PVC – DWV
CPVC
ABS – DWV
Polyethylene
Galvanized steel
Cast iron.
Also the use of short radius 90-degree elbows are often prohibited. You can normally use standard fittings until you reach a certain size at which point you might be required to use drainage pattern fittings (DWV)
Traps
Traps are to be installed as required per the manufactures recommendation. No traps are required on the secondary drain pan, this is to allow immediate notification that the primary drain has failed.
Cleanouts
Cleanouts are required in case of plugged drain pipes. Provide as required to prevent the need to cut drain pipes for unplugging. Some of the following maybe used for cleanouts if approved by your local code authority;
Plugged tees
Union connections
Short clamped hoses at the unit (see image above)
When you have more than one air conditioning unit condensate tied to a main condensate pipe, then every change of direction shall have some method of cleanout. Check your local code as this maybe a requirement for even a single air conditioners condensate piping.
Condensate Pumps
Condensate pumps can be used to elevate the condensate vertically to a point where it will then discharge into a code approved gravity sloping condensate drain line. The condensate pump should be interlocked with the Air Conditioning Unit to prevent its operations if the condensate pump is inoperable.
Please remember that code requirements are always changing, so check for the most current code in your area at the time of design and installation. Or ask an inspector for the current installation practice.

If the project is new construction, then there won’t be much to see except where the proposed building will be set on the lot and some of the logistics such as allowable lay-down area for materials and job site trailers/offices.
For retrofit projects of existing buildings there are some important aspects of the project walk that you will want to be sure to capture while your there if not already provided in the bid documents.
In order to get the most of your time when attending a project Job Walk you should get at least the following information.
Photo or Video of Existing Conditions and Equipment
Its important to take a lot of pictures of the area and equipment that is affected by the renovation. You’ll use these photos or videos back at the office during your review so that you can share what you saw with the team involved with assembling the bid. Often, you’ll see something in the photo that you didn’t notice during the job walk which the photos and videos allow you to review at a more relax environment.
Equipment Labels
Equipment Labels
Make sure to get a good picture of all the existing equipment that needs to be remove or replaced.
Take a picture of the equipment labels that identify the make and model number of the piece of equipment plus all the additional capacity information listed.
Get a picture of the electrical panel that serves the existing, including the inside list of breakers. The photo will also show which breakers are being used and also which are in the off position.
360 Degree View of Area and Equipment
Take a picture on all four sides of any equipment or area involved in the renovation. This is important so that you can review any side of the equipment back at the office.
Auxiliary Equipment and Accessories
Make sure to get pictures of any ancillary equipment that is part of the renovation, such as expansion tanks, plumbing fixtures or electrical.
Electrical panels related to the work if new circuits are required or are to be upgraded.
Control panels or controllers that need to be replaced or upgraded.
Panoramic Views
Step back from the actual equipment as much as makes sense to get a good overall photo of the area of work. Sometimes those walking the project will get good closeup pictures of the equipment but won’t give an overall view of the total area. It’s easy to zoom in on a long shot picture, but that’s impossible with one that is already shot up close.
Job Walk Basics Panoramic Photo – Step Back and Take a Picture from a distance
5) Similar Equipment
Often the project may require you to replace equipment that looks the same, such as replacing all the rooftop Air Conditioners. In this case in order to keep your photos organized as to which photo belongs to which AC unit, you’ll need some way to identify each.
If there are equipment tags on each unit, then take a picture of the tag first and then another for each side of the AC unit or similar equipment before moving onto the next. If there are no equipment tags, then you can make your own by writing on a piece of paper the Equipment Tag, such as AC-1, then taking a photo of your written tag, then each side of the AC unit.
Dimensions of Important Items
The following are some of the items to thing about getting dimensions of while you’re onsite.
Equipment pads or platforms
Dimensions of concrete pads or platforms where the new equipment will sit.
Rigging Pathway
If you are moving old equipment out and new equipment in, then you will need to measure hallways and doorways along the path from the room where the equipment is located to where it enters the building.
Make sure to get all the pertinent photos of the equipment or work area that is part of the contract. For retrofit projects
As-built Drawings (Existing Drawings)
If doing a renovation or a design/build project it’s a good idea to ask the owner, facility engineer or there representative if they have copies of the existing MEP drawings. This can make your job a lot easier if you need to redesign the system.
Existing As-built Drawings
Also, any Architectural or Structural drawings can be useful especially if your replacing equipment on the roof. If the new equipment is heavier or if the structural code has gotten more stringent from the time the building was designed and built, then you might need to submit a structural review in order to confirm that the existing structure can hold the weight of the new equipment.
It best to get these in electronic format or to take pictures of the existing drawings if not available digitally.
Tools to Bring on your Job Walks
Personal Protective Equipment (PPE)
Some form of measuring tape, whether digital or hand held.
PPE Equipment. Some sites require that you bring a Hard Hat, Goggles, Fire Retardant Clothing, Safety Shoes/Boots/Vest, etc. You should always keep a set of PPE in your car, so that you are always prepared for a site walk. Even if it’s not required, it’s smart to wear protective clothing as some equipment rooms contain sharp edges and job site conditions could contain slippery or dirty surfaces.
Cell phone or camera to take pictures and videos.
iPad or note pad for taking notes and writing down dimensions and making sketches.
Flashlight to see dark areas in mechanical rooms, attics or within equipment.
A copy of the construction drawings and scope of work.
Bring Important Subcontractors & Vendor
If you are bidding on a turn key project, one where you are responsible for all of the other trades. This often occurs when the majority of the work is related to the mechanical, such as the replacement of major HVAC or Electrical equipment upgrades.
It’s also most likely that your company specializes in one of the MEP trades and will need to provide another subcontractor to do the other portions of the work. You might be an HVAC contractor that is comfortable replacing the mechanical equipment, but not in upgrading the electrical panels. It’s also possible that quite a bit of new structural work will be required to support the new equipment.
Maybe you want to bring out the manufactures representative of the major equipment that is being replaced. Be prepared to bring your team members that will be involved in providing you with the quotations you’ll need to provide a complete proposal. This is especially important on Design/Build projects where you are responsible to provide a complete and operable system per the intent of the RFP. This is also important in renovation so that your team can assess the existing conditions in order to apply reasonable labor factors.
In the next two test you will be required to measure the lengths of the ductwork using the bar scale shown on each drawing. Print the enclosed drawings or use a distance measuring software program like Bluebeam so that you can accurately measure the distances for each duct length based on the bar scale shown on the drawings, or if you have an estimating program you can import the drawing and do your takeoff.
Another method is to measure the drawing on your computer screen, which can be done by increasing the magnification of the drawing until the bar scale on the drawing matches the hand held scale you hold up to the computer screen.
In the following series of test there will be no numbered items given. It will be up to you to determine what you need. Start as always at the source or the largest duct in this case we have outlined the path to take for you, so that the answer sheet given will follow the same path. Start at the letter “A” on the diagram and proceed in alphabetical order until you finish filling in the takeoff form.
