READ TIME14 Minutes

A challenge many HVAC contractors face is finding the work to expand their business beyond their neighborhoods. Fortunately, there are plenty of websites that post or collect opportunities from both public and private organizations that make this easier than ever, and some can even help you with putting your proposal together or other aspects of the bidding process. In this article, we list some top HVAC bidding websites, and discuss how they can help you bid faster and with greater reach.

How an HVAC bidding website works

HVAC bidding sites offer a digital platform to submit bids for HVAC work, but they don’t radically change the process of interacting with potential customers directly. The basic flow is something like this:  

  • 1
    A customer presents the details of their project and requests proposals. In some cases, bid submission is open to anyone and in other cases, the customer may pre-screen contractors and only invite a small number of them to actually make a bid.
  • 2
    Eligible contractors that determine they can deliver on the items and services the project requests put together proposals outlining how they plan to fulfill the project’s goals, then submit them.
  • 3
    The customer reviews the submitted proposals, selects which contractor(s) to give the project to, and lets them know.
  • 4
    The contractor(s) chosen for the project communicate with the customer to negotiate the specific terms & conditions.
  • 5
    Once a contract is finalized, work on the project begins.

Moving this process to an online HVAC bid list expands the reach of both contractors and clients, allowing them to connect for more jobs over greater distances. It also makes the process more useful and easier to manage for both clients and contractors. The next section will expand on these points.

Using software to structure and put together your bid proposal is another way to make bidding – online or otherwise – more efficient. We explain more in our article on how to choose the best HVAC bidding software for your business.


4 features to look for in an HVAC bidding website

There are many advantages to managing your HVAC bids online if you find the right platform. Here are four general qualities you should look for in a bidding website to ensure you’re getting the most benefit. 

1. Access to a network of clients in your general service area

Moving the HVAC bidding process online allows you to overcome time and distance constraints by letting contractors access larger pools of projects over wider areas. It’s then up to the contractor how flexible they want to be in terms of how far they’re willing to travel for the work.

2. User-friendly interface & task assistance

A good HVAC bidding website will provide tools that assist with tasks related to submitting bids. This may include providing templates to structure a bid proposal, tracking the statuses of bids, and allowing you to manage or submit bids with just a few clicks. The idea is to cut down on manual administrative work so your bids get out to clients faster.

Our article on commercial HVAC bid templates gives an example of a template designed for commercial HVAC bids, as well as a list of other templates you can use for commercial HVAC proposals. You can also check out our article on HVAC bid templates for a more inclusive list.

3. Speeds up and automates the bidding process

An HVAC bidding website with tools to speed up proposal reviews for clients is helpful for contractors as well. It sets clear expectations for what proposals need to include, and helps all parties move quicker to negotiations and, eventually, getting work done.

4. Real-time updates

Instant notifications is another key feature to look for in HVAC bid websites. Knowing if a bid has been accepted or rejected anytime, anywhere leads to faster decision-making on whether to prepare for negotiations or chase a different lead. It also keeps open communication between contractors and clients, which helps to increase transparency and minimize misunderstandings.

4 other ways to find HVAC bid opportunities

At this point, you may be asking: “How else can I find HVAC bids near me?” We’ll reiterate that we think bidding on HVAC contracts online with websites like the ones listed above is the most efficient way to expand your business. However, if you’re starting small and want to stick to local projects, there are a few other options available:

  • 1
    General contractors – Some general contractors will have jobs they’re looking to subcontract out if you look on their websites or contact/visit their headquarters.
  • 2
    Classified advertisements – Some large city newspapers, as well as certain small local newspapers, will have sections called “Bids and Proposals” where you can find contact information for people or companies soliciting jobs. 
  • 3
    Technical shops – Shops that provide hardware and other services for tradespeople may sometimes have “bid boards” where general contractors will post jobs they want to hire subcontractors for.
  • 4
    Lead generation software – Some field service management platforms have built-in (or add-on) tools that will automatically search different sources for available bids. With ones like BuildOps’ Pipeline+, you can even customize what kinds of bid opportunities you get based on the types of work your contracting team specializes in.


When it comes to how to find HVAC bids, the sites we listed above are good starting points. When it comes to managing an HVAC project after you’ve won the bid for it, count on BuildOps. It’s built for commercial contractors with features not often found in other field service management software like advanced non-exact searching your customer and project details to help you find information more easily, asset management hierarchies for clients that own more than one serviced property, AI that speeds up notetaking and report writing, and customizable workday lists of “need-to-input” information.
