Quoting Common HVAC Repairs: Capacitors, Contactors, Drain Lines and Blower Motors

Most HVAC repair calls end with one of a handful of fixes. A capacitor that gave up in the heat. A contactor with pitted points. A drain line full of slime that tripped the float switch. A blower motor that hums but will not spin. These repairs come up so often that every one of them should be a ready-made line on your service list, priced and described before the first call of the season.

Why Common Repairs Need Ready-Made Lines

The previous guide, Quoting HVAC Repairs on Site: From Diagnosis to a Written Estimate Before You Leave, made the case for getting a written estimate to the customer before the van leaves. That only works if writing the estimate is quick. If the tech has to look up a part cost, add labor, round it, and type a description every time, it will not happen in the driveway.

With each common repair on the service list in HVACBossPro, the estimate is a few taps: diagnostic, repair, maybe an option, and tax is figured. The price is the same no matter which tech found the problem.

Capacitors

The single most common summer repair at many shops. Set it up as one line that covers the part and the labor: “Replace outdoor unit run capacitor.” If you stock different types, consider separate lines for a single capacitor and a dual run capacitor rather than one vague line.

Description example: “Replace failed run capacitor that helps start and run the outdoor fan and compressor. Test operation after replacement.” The customer does not need to know microfarads. They need to know what it does and that it was tested afterward.

Contactors

Often found alongside a capacitor problem. A separate line, “Replace outdoor unit contactor,” lets you quote it on its own or together. Some shops add a combined line for both at a slightly lower price than the two separately, which gives the customer a reason to approve both at once. That is a pricing choice for you to make, not a rule.

Condensate Drain Lines

A clogged drain line can shut down the system or leak through a ceiling, so it is a repair customers usually approve quickly once they understand it. Set up “Clear and flush condensate drain line” as a line. If you also install drain line cleanouts or float switches, give each its own line.

This is also a good place to put a maintenance reminder in the description: “Clearing the drain line once or twice a year helps prevent overflow and water damage.” It is honest, and it points toward a maintenance plan.

Blower Motors, Thermostats and Coil Cleaning

Blower motors vary widely in cost by type and size. Rather than one line with a single price that is wrong half the time, many shops keep a few: standard motor, variable-speed motor, and so on. The tech picks the right one, and the equipment details on the estimate, such as the brand and model of the air handler or furnace, show what system it is going into.

Thermostats are usually two or three lines: replace with a basic programmable model, replace with a customer-supplied thermostat, or install your recommended model. Write what is included, such as removal of the old unit and setup.

Coil cleaning can be indoor, outdoor or both. Separate lines let the customer choose. Coil cleaning is also a natural option to add on any repair estimate, as described in Good, Better, Best HVAC Quotes: Writing Options as Separate Estimate Lines.

Keep Descriptions Short and Honest

Every line on a repair estimate should answer three questions in a sentence: what is broken, what you will do, and why it matters. Avoid scare language. “Your system could fail at any time” is true of every machine ever built and makes customers suspicious. “The capacitor is reading well below its rating and is likely to fail soon, which would stop the outdoor unit from running” is specific and believable.

A before photo from the tech app of the bulged capacitor or the corroded contactor goes a long way. It keeps the conversation about the equipment instead of about trust.

From Quote to Repair to Invoice

Once the customer approves online, the approved estimate becomes the scheduled job, or the tech does the work right then if the part is on the truck. The same lines carry onto the job, and when the tech taps Complete, the invoice is created and a card on file can be charged. The capacitor the customer approved at $185 is billed at $185, plus the tax they already saw.

Over time, the service list also tells you something useful: which repairs you quote most often. If drain lines show up on half your summer estimates, that is a strong argument for including drain line clearing in your tune-up and maintenance plan.

Refrigerant needs a slightly different kind of line, priced per pound, and that is the next guide in the series. For everything else about quoting and approvals, return to the HVACBossPro HVAC estimate software page.
