Maintenance visits that are really a walk-through
The giveaway is no measurements. A real visit produces numbers per asset, which is why the log belongs in the agreement rather than in the small talk.

Heating, cooling and refrigeration maintenance
This is the only entry in the catalog that reliably reduces the rest of it. A standard visit covers every rooftop unit, split system, walk-in, freezer and reach-in run on the premises: coils cleaned, filters replaced, belts and bearings checked, charges verified, temperatures logged. Two visits a year is the usual pattern, and the point is to convert emergency callouts into scheduled ones, because emergency work is the most expensive way to buy any of this.

What heating, cooling and refrigeration maintenance costs
Most of these jobs land near $780. The full spread runs $320 to $2,400, and the gap between those two ends is diagnosis against replacement rather than one business being dearer than another.
What moves it: how much of the job is parts, whether the fault is found in the first hour or the third, access to the equipment, and the hour of the day you call. We never speak to the businesses listed here, so there is no rate card behind any of this. It is our own band for the category, and there is no regional index: the figure does not change with your metro.

Our estimate from national cost bands, not a quote from any business. Every row is the same band with the urgency multiplier the site applies everywhere else, so this table can never contradict the headline number. Ask for a written price before the work starts.
Who is licensed to do this work
In California the classification that squarely covers this is C-20 warm-air heating, ventilating and air-conditioning or C-38 refrigeration, and the register says who holds it. Every listing on this site shows the classification, the license number and the date we read it, with a link back to the register entry so you can check it against the state rather than against us.
Overlapping classifications exist and are labeled as overlapping rather than as a match: C-4 boiler, hot water heating and steam fitting, C-43 sheet metal and D-62 air and water balancing. A general building contractor may hold the job and subcontract the trade, which is a real answer and a different one, so the card says which of the two you are looking at.
One thing worth being plain about: CSLB classifications do not distinguish commercial work from residential. There is no separate commercial license to hold and no register field that would prove one. That is why this page describes the equipment rather than the contractor, and why nothing here says a business has been checked out. We read a public record on a stated date. That is the whole claim.
Before you pay for a callout
Two minutes of checks that sometimes end the problem
We would rather you did not need a callout at all. These are the checks that end the most calls for this fault.
Try a quick fix first
Some issues resolve without a truck roll. Two minutes now can save the callout.
- 1
List every asset before you ask for a price: rooftop units, split systems, walk-ins, freezers, reach-in runs, ice machines, prep tables. Missing assets is the main reason maintenance prices vary so wildly between contractors.
- 2
Ask for the temperature and pressure log as a deliverable. Without it you have bought a visit rather than a record.
- 3
Book both seasonal visits at once. It is usually cheaper and it gets you a slot before the rush.
What the visit actually includes
- Condenser and evaporator coil cleaning on every unit
- Filter replacement throughout
- Belt, bearing, capacitor and contactor inspection
- Refrigerant charge and superheat verification
- Temperature log for every refrigerated asset
- Written list of what is likely to fail in the next six months
Diagnosis
How maintenance visit faults usually present
Written from how these faults actually present on a working premises, not from a manual.
Assets quietly left off the schedule
Ice machines, back-room unit heaters and under-counter fridges are the usual omissions, and all three then fail as emergencies.

By location
Heating, cooling and refrigeration maintenance near you
Local pages show which businesses are listed for that metro, how far out they sit, and the local conditions that drive demand.
Counted from the businesses we have imported for each metro center inside a 25 mile radius, and counting only those whose own license classification names this trade. General contractors licensed widely enough to take it on and subcontract it are excluded here, and still appear in a search. A metro reads “none yet” until we load a register that covers this trade there.

Maintenance visit FAQs
Short, specific answers. If yours is not here, ask the business you call before you agree to the visit.
How often should we schedule?
Twice a year for heating and cooling, twice a year for refrigeration coil cleaning, and more often in hot, greasy or dusty environments. A kitchen fouls a condenser far faster than an office does.
Can one contractor cover both heating and refrigeration?
Frequently yes, because commercial refrigeration and air conditioning overlap heavily. In California look for a business holding both C-38 and C-20, which the listings here show from the register.
Is a maintenance contract worth signing?
The value is in the schedule and the priority, not the discount. Read what happens on a breakdown call: response time and whether parts are included are what actually differ between agreements.
