Heat Pump Electrical Wiring
Replacing like for like still changes the load more often than people expect. Hot tubs, pools and saunas carry their own rules, and the inspector will know them even if the installer did not.
Heat Pump Electrical Wiring in O’Fallon and across St. Charles, St. Louis, Lincoln and Warren counties.
Owner-operated: the person who answers the phone is the person who measures it.

What this work actually involves
Terminations are torqued to spec, which is the single most common thing missed on appliance work.
Nothing gets quoted off a description. The reading comes first, because a symptom has several possible causes at very different prices and only a measurement separates them.
Where a permit and an inspection are required they happen, and the site is left ready for them. One person carries the job from the first call to the final test.
When people call about this
- A hot tub waiting on power
- A breaker that trips on a cycle
- An appliance with a scorched plug
- A pool pump on a shared circuit
Why people choose Clint for it
The diagnosis and the repair are the same person’s work, which is why the explanation you get is first-hand rather than relayed.
Five point zero from 94 Google reviews, A+ with the BBB since December 2022, and seventeen years in the trade behind it.
Where this is done
A roughly fifty mile working radius from O’Fallon, covering thirty municipalities across five jurisdictions in the St. Louis metro.

Read the data plate, not the old circuit
Every appliance states what it expects: volts, amps or watts, and often the circuit size. That plate is the specification, and a replacement appliance frequently asks for more than the one it replaced.
Same-size replacements still change things. Induction cooktops and heat-pump dryers draw differently from what was there in 1996.
The data plate settles it
Every appliance carries a plate stating what it draws and what circuit it needs. That plate, not the old circuit and not the showroom brochure, governs the install, and it is the first thing to look at when a new appliance will not run right.
A replacement frequently draws differently from what it replaced. Induction asks more than a coil range, a heat pump water heater asks differently from a resistance one, and a modern dryer is not the dryer the circuit was run for.
Heat pump circuits in this climate
A heat pump has a compressor circuit and usually auxiliary heat strips, and the strips are the larger load. Sizing for the compressor alone is the common error.
The plate governs: circuit, disconnect in sight of the unit, and whip to the condenser. Load against the service gets calculated because heat pumps and chargers arriving in the same year is what fills a service.
Permits, inspections and why they vary here
Requirements genuinely differ across this metro. O’Fallon, St. Charles, St. Peters, the St. Louis County municipalities and St. Louis City each run their own process, and what one treats as a minor repair another permits and inspects.
Work that needs a permit gets one, and work that needs an inspection is left ready for it with the panel labeled and the junctions accessible. That matters most before a closing, when an inspector’s written item becomes someone’s negotiating position.
Who actually does the work
Clint Ehman does the diagnosis and the repair himself. There is no salesman writing a scope for a technician to execute, and nobody paid on what the visit totals.
Seventeen years in the trade, four of them running his own shop out of O’Fallon, licensed, bonded and insured with workers compensation coverage, 5.0 from 94 Google reviews, and A+ BBB accreditation held since 2022.
“Clint came out installed me a large 200 amp panel put some new dedicated lines in my basement and garage he did great clean work all inspections passed he was thorough and knowledgeable. I will have him back out again.”

How the visit goes
- The call
Which appliance, and whether it is new, replacing something, or failing.
- The measurement
The appliance’s data plate against the existing circuit, and the condition of the terminations at both ends.
- The finding
Whether the circuit is right, needs upgrading, or is fine and the problem is a connection.
- The work
Circuit matched to the plate, disconnect and bonding where water is involved, terminations torqued to specification, tested under load.
What the job includes
- Circuit matched to the appliance’s own data plate
- Disconnects and bonding where water is involved
- Terminations torqued to specification
- Correct receptacle or hardwired connection as the appliance requires
- Permit and inspection where required
- Testing under load before we leave
What it does not
- Supplying or repairing the appliance
- Plumbing and gas connections
- Appliance haul-away
Work that is not electrical gets a referral, not a quote. Recent jobs are worth a look before you call.

Heat Pump Electrical Wiring across the metro
Where the house is changes what the work involves. What an inspector looks at first differs by address here, which shapes the job as much as the house does.
St. Louis County
The obsolete panel brands concentrate in this county, because they were installed through exactly the decades this housing was built and upgraded.
St. Louis City
St. Louis City is century brick with shared walls and basement panels that have been added to five times. Code corrections and occupancy inspections are the common call.
Lincoln County
Outages last longer this far from town, which changes the backup conversation from comfort to the pump.

Questions worth asking first.
My new appliance will not run. Is it the appliance?
Often it is the circuit. The data plate states what the appliance expects, and comparing that to the existing circuit usually explains it in one visit.
Does a hot tub need its own disconnect?
Yes, with bonding, and placement is specified by code. It is one of the items inspectors check first on spa work.
Will my induction range fit the existing circuit?
Often not. Induction generally draws more than the coil range it replaces, and the appliance data plate settles it before delivery day.
Where do you work?
Out of O’Fallon across St. Charles County, St. Louis County, St. Louis City, and Lincoln and Warren counties, roughly a fifty mile radius.
Do you pull permits?
Where the municipality requires one, yes, and the work is left ready for inspection with the panel labeled and junctions accessible. Requirements genuinely differ across this metro, which is why it is established per address rather than assumed.
