A residential HVAC technician installs, maintains, and repairs the heating and cooling systems in people's homes — split-system air conditioners and heat pumps, furnaces, and ductless mini-splits.
It is the house-call side of the HVAC service technician role: one home, one system, and a repair that has to hold.
Here is the equipment, the in-home work, the seasonal calendar, the pay plans, and the move to commercial.
Typical residential equipment
The federal occupation definition already sketches the residential job.
O*NET defines Heating, Air Conditioning, and Refrigeration Mechanics and Installers (SOC 49-9021.00) as workers who install or repair heating, central air conditioning, HVAC, or refrigeration systems, including oil burners, hot-air furnaces, and heating stoves.
Residential service is that definition pointed at houses, and the wider role is covered in our HVAC service technician guide.
The residential line-up is the trade's small-system list: split systems, furnaces, ductless mini-splits, and heat pumps.
Heat pumps are a measurable slice of the housing stock — in EIA's 2020 Residential Energy Consumption Survey, 16.13 million of 123.53 million U.S. homes (13%) used a ducted heat pump as their main heating equipment, 1.06 million used a ductless mini-split, and 12.52 million of the ducted heat-pump homes were in the South.
Two Department of Energy efficiency floors apply to the equipment above.
New split-system heat pumps have had to meet at least 14.3 SEER2 and 7.5 HSPF2 nationally since January 1, 2023 (10 CFR 430.32(c)(5)).
Split-system central air conditioners manufactured since January 1, 2023 must meet at least 13.4 SEER2 nationally — and units installed in DOE's Southeast or Southwest regions must meet 14.3 SEER2 (under 45,000 Btu/h) or 13.8 SEER2 (45,000 Btu/h and up), a rule that keys to where the unit is installed, not where it was made.
The refrigerant side is certified work.
Under the EPA's rule at 40 CFR 82.161, anyone who could reasonably be expected to violate the integrity of a refrigerant circuit while maintaining, servicing, or repairing appliances containing regulated refrigerants must pass an exam from an EPA-approved certification program — and Type II certification is the type that covers residential split-system air conditioners and heat pumps.
BLS also notes that some technicians specialize in areas such as radiant heating systems, testing and balancing, or commercial refrigeration, and that some specialize in installation while others repair and maintain systems.
Residential service work sits on the maintain-and-repair side of that split, run on the home equipment above.
Working in customers' homes
The segment's real dividing line is where the work happens and who the work is for.
A residential call puts you at a customer's home, and the visit exists because a system needs attention — a repair, a maintenance visit, or a replacement quote.
The duties BLS lists for the occupation read like that day: installing, maintaining, and repairing HVACR systems; installing electrical components and wiring; inspecting and testing systems; discussing system malfunctions with customers; repairing or replacing parts; recommending maintenance; and keeping records.
The people side is measurable in the task data, not just soft-skill talk.
O*NET rates "Discuss heating or cooling system malfunctions with users to isolate problems or to verify that repairs corrected malfunctions" as the highest-importance core task for HVACR mechanics, at 85 on its importance scale.
The technical tasks sit right behind it: testing electrical circuits or components for continuity with electrical test equipment (83), repairing or replacing defective equipment, components, or wiring (81), and laying out and connecting control wiring from wiring diagrams (81).
The visit itself is its own topic: our guide to what happens on an HVAC service call walks the call from dispatch to invoice.
Seasonality
Seasonality in this trade is a schedule fact before it is anything else: BLS describes most HVAC technicians as full time, with schedules that may include evening or weekend shifts and on-call duty for emergencies — and sometimes overtime or irregular schedules during peak heating and cooling seasons.
That description covers the occupation, not the residential segment specifically.
The survey data puts one number on the extra hours: in O*NET's survey of HVACR mechanics, 17% report a typical week of more than 40 hours and 83% report 40 hours.
Our research found no primary data on on-call rotations or calls per night — treat any pattern you hear about as that shop's own; it varies by employer.
Pay plans common in residential work
Our research has no data on which pay plans are common in residential work.
The structures to understand — hourly wage, flat rate (a set price per job), commission, and spiffs — are explained structure by structure in our guide to hourly, flat-rate, commission and spiff pay.
Three federal pay rules attach to these plans.
Flat-rate pay does not remove overtime: for a flat-rate or day-rate worker, the regular rate under the FLSA is total job pay divided by hours actually worked, plus an extra half-time for each hour over 40 in a workweek.
Commissions count as pay for hours worked and must be included in the regular rate for overtime, whether or not they are the only pay.
And the narrow overtime exemption for commissioned employees of a retail or service establishment (FLSA section 7(i)) applies only if the regular rate is more than 1.5 times the minimum wage and more than half the pay over a representative period of at least one month is commissions.
The federal wage data has no residential line to point at: BLS publishes no separate wage for residential versus commercial HVAC work.
The closest published figure is the combined occupation's — a median of $29.33 an hour ($61,010 a year) for Heating, Air Conditioning, and Refrigeration Mechanics and Installers (SOC 49-9021) in May 2025, per OEWS.
That median is the occupation's, not a residential figure — the full percentile and state tables are on the HVAC service technician salary page.
Pay-plan rules are federal law — verify before you rely on them
Moving to commercial later
The move starts from a shared base.
Federally this is one occupation: residential and commercial work share SOC 49-9021.
And the certification requirement at 40 CFR 82.161 keys to refrigerant circuits and appliances, not to building types.
What changes is the equipment classes.
A residential technician's Type II certification covers medium-, high-, and very-high-pressure appliances — except small appliances, MVACs, and MVAC-like appliances — the class that includes the split systems and heat pumps they already service.
The commercial side adds equipment outside that class: low-pressure appliances, such as chillers using refrigerants like R-11, R-123, R-113, or R-245fa, require Type III certification.
Check which type covers the equipment a shop runs, and add a type through an EPA-approved program if you need one.
Demand does not force the choice, either.
BLS expects commercial construction — data centers included — and residential construction to drive HVAC employment growth, along with more sophisticated climate-control systems and retrofit and replacement work, with employment projected to grow 10.9% from 2025 to 2035 and about 40,600 openings a year.
