Near me is answered by geometry here, not by a city label. We measure from your ZIP to the address each business filed with its licensing authority, keep everything inside 25 miles and rank on distance. Nobody buys a place in that order, and nothing about the ranking is ours to sell.

Check your ZIP against the directory. The ring starts at 25 miles and steps out to 75 before we return an empty result.

How the result is built

How a rooftop hvac search near you is put together

Four steps, none of them a ranking anyone can buy into. The order you see is distance, and the reason a name is missing is that we have not imported the register it sits in.

1
Filter on trade first
Only businesses whose register entry covers rooftop hvac work enter the pool. A general handyman with the right ZIP does not.
2
Measure from your ZIP
Distance is straight line from your ZIP to the address the business filed with its licensing authority, and that address is often a home, so we never print it. Only businesses inside the ring you asked for survive this step.
3
Rank on distance, then on what we hold
Nearest first. A phone number and a license row break a tie between two businesses the same distance out, because those are the two facts that make a listing worth calling.
4
Widen only if the ring comes back thin
If fewer than three businesses clear the filters, the radius steps out toward 75 miles and the page tells you it did. The distances you then see are the real ones.

Every metro we cover Coverage by state

What a commercial HVAC repair is licensed for here

In California the classification that squarely covers this work is C-20 warm-air heating, ventilating and air-conditioning. Every listing here shows the classification, the license number and the date we read it off the register, with a link back to the entry.

There is no commercial version of C-20 to hold. The register records the classification and nothing about the premises it gets worked on, so commercial HVAC repair on this page describes the equipment and the site rather than a credential the state issued.

Questions owners ask

Rooftop HVAC near me: the questions we get

Answers hold anywhere. Where your state sets a rule that changes one of them, ask the business to put it on the written price before you agree to the visit.

Find local trades

Who is responsible, me or my landlord?

Read the lease before you call. Most commercial leases put rooftop units on the tenant for service and on the landlord for replacement, and the line between a repair and a replacement is exactly where those arguments happen. Get the diagnosis in writing either way.

What does a rooftop unit repair cost?

Routine repairs land between $260 and $900. Compressor replacement runs into the thousands, at which point replacing the unit deserves a look. Those are our national bands, not a quote from anyone listed here.

How often should filters be changed?

Quarterly as a baseline, monthly if you have a fryer, a lot of dust or a lot of people. It is the highest-return maintenance task on the roof.

What license does this need?

C-20 in California, warm-air heating, ventilating and air-conditioning. Every listing here shows the classification and license number from the state register.
