What good looks like, by problem

Fifteen problems every AC, plumbing and electrical company runs into, and the habits the best shops use to fix them.

Missed calls

Calls ring out at lunch, after 5 and on the first hot or cold day, and most of those callers don't call back.

What good looks like

  • Aim to answer at least 9 in 10 calls live during business hours.
  • Aim to pick up within about 20 seconds.
  • Every voicemail and missed call returned within minutes, not by the end of the day.

Best practices

  1. Measure your true answer rate by hour of day, not your gut feel. Most owners guess high.
  2. Cover the gaps on purpose: lunch, the first and last hour of the day, Saturdays and the first big weather day.
  3. Set an overflow rule: after a set number of rings or calls waiting, calls roll to a second person or an outside team.
  4. Return every missed call fast, with a named owner for the call-back list.
  5. Write a short after-hours plan: what counts as an emergency, who is on call and what the caller is told.
  6. Listen to five recorded calls a week and coach one thing at a time.

Slow response to new leads

Web forms, ad leads and quote requests wait hours for a call back, and by then the homeowner has booked someone else.

What good looks like

  • Aim to call every new lead within 5 minutes during business hours.
  • At least three attempts over the first two days, by call and text.
  • One named owner for new leads every hour you are open.

Best practices

  1. Send every lead source to one place, so nothing sits in an inbox.
  2. Call first, then text if there is no answer. Leave a short voicemail with a call-back number.
  3. Make three attempts in the first 48 hours, at different times of day.
  4. Time your response for a week. What gets measured gets faster.
  5. Know what each lead source costs per booked job, not just per lead.
  6. Plan who covers new leads at night and on weekends, when many forms come in.

Customers who never hear from you again

Thousands of past customers sit in your software. Their equipment ages, their plans lapse, and nobody calls them.

What good looks like

  • A clean list with a working phone number and the equipment age for most customers.
  • Every customer contacted at least once or twice a year.
  • Aging equipment flagged before it fails, not after.

Best practices

  1. Clean the list first: remove duplicates, fix phone numbers and mark do-not-call customers.
  2. Sort by what predicts a sale: equipment age, last visit and open repairs.
  3. Start with the warmest groups: lapsed members, recent repairs on old equipment and unsold estimates.
  4. Lead with a reason to visit, such as a safety check or no-charge inspection, not a sales pitch.
  5. Call during your slow weeks, so the work lands when you have room on the board.
  6. Track every campaign from call to sold job, so you know what to run again.

Unsold estimates

Techs give good options, the homeowner wants to think about it, and the estimate is never mentioned again.

What good looks like

  • Every open estimate has an owner, a next step and a date.
  • A first follow-up within two days of the visit.
  • Estimates reviewed weekly, oldest and largest first.

Best practices

  1. Leave every estimate in writing, with options and a monthly payment.
  2. Call within 48 hours, and ask what questions came up, not whether they are ready.
  3. Plan a short sequence: day 2, day 7, day 30, then seasonally.
  4. Offer a second visit to answer questions for larger jobs.
  5. Track why estimates are lost, and coach to the top reason.
  6. Keep unsold estimates on the list for future outreach.

Empty slots and the shoulder season

The board is full in peak season and thin in spring and fall, while payroll and trucks cost the same every month.

What good looks like

  • Your slow months planned at least four to six weeks ahead.
  • A target for how full each day should be, by trade and area.
  • Fill work ready to book: tune-ups, inspections and lapsed members.

Best practices

  1. Look at last year's board by week, and mark the soft weeks before they arrive.
  2. Start calling past customers four to six weeks before the slowdown.
  3. Book by area and time window, so trucks aren't crossing town.
  4. Keep a short list of easy yes visits: tune-ups, safety checks and filter or water heater service.
  5. Hold back a slot or two each day for emergencies in peak season.
  6. Review fill every morning and push the next three days first.

No-shows and cancellations

The truck shows up and nobody is home, or the visit is cancelled the morning of.

What good looks like

  • Aim for 7 or 8 of every 10 booked visits to happen as scheduled.
  • Every booking confirmed back to the homeowner on the call.
  • A reminder the day before and the morning of.

Best practices

  1. Read the booking back: date, window, address and phone number, in the homeowner's words.
  2. Tell them why the visit matters to them, not just when it is.
  3. Send a confirmation right away and a reminder the day before.
  4. Call or text when the tech is on the way, with a name and photo.
  5. Track no-shows by reason and by who booked them.
  6. Rebook missed visits the same day.

Maintenance plans that lapse

Members sign up once, the renewal date passes quietly, and the plan is gone.

What good looks like

  • Renewals worked 60 days before they are due.
  • Every member visit scheduled, not waited for.
  • A renewal rate you track every month.

Best practices

  1. Schedule member visits proactively each season.
  2. Start renewal calls 60 days out, with a reminder at 30 days.
  3. Show members what they got: visits, discounts and what the tech found.
  4. Make renewing easy, with auto-renew where your state allows it and a clear way to cancel.
  5. Call lapsed members within 90 days with a reason to come back.
  6. Treat plan members as your first list for every campaign.

Welsch Heating & Cooling

Close rate and average ticket in the home

The visit happens, but the homeowner doesn't hear options they can understand, and the work goes to someone else later.

What good looks like

  • Every visit ends with written options: good, better and best.
  • Financing offered on every larger option.
  • Close rate and average ticket tracked by tech, every month.

Best practices

  1. Use the same inspection checklist on every visit, so nothing is missed.
  2. Show photos of what the tech found before talking price.
  3. Present options in writing, with a monthly payment on each.
  4. Ask for the decision, and accept "not today" without pressure.
  5. Ride along and role-play monthly. Coach one habit at a time.
  6. Hand unsold options to a follow-up process, not the tech's memory.

An overwhelmed dispatcher

One person answers the phones, runs the board, calms customers and chases techs. Something always slips.

What good looks like

  • Phones and the board are not the same person's job in busy hours.
  • The next day's board is built the afternoon before.
  • Customers hear about changes before they ask.

Best practices

  1. Separate answering from dispatching during peak hours.
  2. Build tomorrow's board by 3 PM, grouped by area.
  3. Match job types to tech skills before the day starts.
  4. Text customers about delays before they call.
  5. Keep a short list of who to call when a tech runs long.
  6. Debrief the day for 10 minutes: what slipped and why.

Hiring and keeping good techs

Good techs are hard to find and easy to lose, and every departure costs months of production.

What good looks like

  • You know your turnover rate and why people leave.
  • Every new tech has a 90-day plan and a mentor.
  • Pay, growth and recognition are clear and written down.

Best practices

  1. Hire for attitude and teach the trade, with a clear path from helper to lead.
  2. Plan the first 90 days: ride-alongs, checklists and weekly check-ins.
  3. Hold stay interviews with your best people before they think about leaving.
  4. Make pay plans simple enough to explain on one page.
  5. Use a fair scorecard, and coach before you correct.
  6. Remove the frustrations that make techs quit, such as bad routes, missing parts and chaotic days.

Reviews and the customer experience

Happy customers rarely leave a review, and one bad experience can cost you a customer for life.

What good looks like

  • A review request after every completed job.
  • Every review answered, good or bad, within a few days.
  • Your rating and review count tracked monthly.

Best practices

  1. Ask for the review the same day, while the visit is fresh.
  2. Send the link by text, so it takes one tap.
  3. Never offer anything in exchange for a review, and ask every customer, not just happy ones.
  4. Reply to every review, and take problems offline fast.
  5. Listen to calls and read reviews for patterns, then fix the cause.
  6. Make the first call and the arrival feel professional: names, windows and updates.

Pricing and knowing your numbers

Revenue looks fine, but margins are thin and nobody is sure which jobs, techs or lead sources make money.

What good looks like

  • A handful of numbers reviewed every week.
  • Prices built from your real costs and target margin.
  • Cost per booked job known for every lead source.

Best practices

  1. Pick five weekly numbers: answer rate, booked jobs, close rate, average ticket and revenue per tech.
  2. Price from your true hourly cost, including drive time and overhead.
  3. Review prices at least once a year and when costs change.
  4. Track every job back to the source that created it.
  5. Cut the lead sources that cost more than they bring in.
  6. Share the numbers with your team, so everyone knows the score.

Running on spreadsheets

The schedule, customers and estimates live in spreadsheets, notebooks and people's heads. It works until you grow.

What good looks like

  • One system for customers, jobs, estimates and invoices.
  • Everyone sees the same board, live.
  • Customer history available on every call and every visit.

Best practices

  1. List what lives where today before you pick software.
  2. Clean your spreadsheet before you import it.
  3. Move one thing at a time: customers, then scheduling, then estimates and invoices.
  4. Train each role on the few screens they use.
  5. Set a date to stop using the old sheet, and keep to it.
  6. Review after 30 days and fix what people work around.

Calling rules and compliance

Calling and texting customers comes with rules on consent, timing and opt-outs, and the rules change.

What good looks like

  • Consent recorded for every text and marketing call.
  • Do-not-call lists checked before every campaign.
  • Opt-outs honored right away, in every channel.

Best practices

  1. Scrub lists against the national and state do-not-call registries before calling.
  2. Keep a record of consent for marketing texts and calls.
  3. Honor opt-outs fast, however the customer asks.
  4. Call only within allowed hours in the customer's time zone.
  5. Watch the Updates page for rule changes and dates.
  6. Ask your attorney when a rule is unclear.

The owner is the bottleneck

Everything runs through the owner, so growth stops when the owner's day is full, and the business is hard to sell.

What good looks like

  • The business runs for 30 days without you.
  • Each key job has a written process and a person who owns it.
  • You spend more time on the business than in it.

Best practices

  1. Write down the jobs only you do today, and hand off one a month.
  2. Put processes in writing: booking, dispatch, sales follow-up and billing.
  3. Give people numbers to own, and review them weekly.
  4. Hire or outsource the work that ties you to the phone.
  5. Keep clean books and records a buyer or lender can trust.
  6. Plan your exit years ahead, even if you never sell.
