AC Repair in Hudson, Colorado

Hudson sits at exactly 5,000 feet, which makes it the cleanest piece of arithmetic on our service map: a 12.0% gas derate under the NFPA 54 convention of 4% per 1,000 feet above 2,000 feet, and air about 13.8% less dense than at sea level. It is also a Weld County address, which means replacement work routes differently from the Adams County towns a few miles south. We have been running this corridor since MoJo Home Services opened in 2009. Reach us on 720-807-4050 — licensed, insured, EPA-certified, and no part gets named before the readings are taken.

What does exactly 5,000 feet do to an air conditioner in Hudson?

It costs capacity on the air side. Cooling depends on the mass of air moved across the evaporator, not the volume, and at 5,000 feet each cubic foot carries about 13.8% less mass than at sea level. Where a sea-level design sheet says 400 per ton, Hudson wants about 464. The total-heat constant of 4.5 becomes about 3.88, and the sensible-heat constant of 1.08 becomes about 0.93. A three-ton Hudson system measuring a textbook 1,200 CFM is delivering the mass-flow equivalent of closer to 2.6 tons, which is why an apparently correct system still falls behind on a design day.

Why is refrigerant charge the most misread measurement in Hudson?

Because manufacturer superheat and subcooling charts are printed for standard air, and at 5,000 feet the air crossing both coils is not standard. A technician who reads those charts literally in Hudson sees numbers that suggest an undercharge and adds refrigerant to a system that was never short. That raises head pressure, increases compressor discharge temperature, and shortens equipment life while the actual fault — usually airflow well below 464 CFM per ton — goes untouched. The correct sequence is to establish airflow with a static-pressure reading first, then interpret subcooling with that airflow known. Charge is a conclusion, not a starting point.

What fails most often on Hudson air conditioners?

Capacitors that no longer measure what the case says they should, contactors worn by repeated switching, outdoor coils packed with dust and seed off open Weld County ground, drain lines that clog until a float switch cuts the system, and refrigerant creeping out of flare fittings and valve stems a few ounces a season. On systems that have been topped off more than once, the leak is still there and the accumulated overcharge has usually made the symptoms worse. We look for the leak rather than refilling around it.

Which repairs are worth doing on an older Hudson system?

Refrigerant type usually decides it. Anything from before about 2010 will almost certainly be an R-22 machine, and R-22 has not been produced in or imported into this country since 2020 — every pound now comes out of reclaimed stock, spent on a unit already close to the end of its life. Systems charged with R-410A are a different matter; parts and refrigerant are both ordinary. Equipment sold new today ships on R-454B, the result of a phasedown that took effect in 2025. Electrical repairs — capacitors, contactors, fan motors — are almost always worth doing regardless of age. Sealed-system work on R-22 in Hudson rarely is.

Who permits air conditioning replacement in Hudson?

Weld County, not Adams. Hudson is a Weld County town of 1,571, and equipment swaps here follow the county's building department rather than the routing used for Henderson or Commerce City to the south. Replacement documentation should show a load calculation built on 5,000 feet and a 12.0% derate, and the condenser should be paired with an AHRI-matched indoor coil. A mismatched coil undermines both rated capacity and any subsequent charging measurement.

What does Hudson's exposure do to outdoor equipment?

Open ground means wind-carried grit reaching the condenser coil with nothing to slow it, and unshaded units taking full afternoon sun. Both raise condenser approach temperature, and at 5,000 feet the coil is already rejecting heat into air 13.8% thinner than its rating conditions. Annual coil cleaning recovers real capacity here without opening the sealed system, and a level pad with proper clearance around the unit does more for longevity than most add-on accessories.

Weld and Adams County neighbours

Lochbuie sits southwest and straddles the same county boundary question. Fort Lupton is the other Weld County town on this route, and Henderson, 23 feet higher at 5,023 feet, is Adams County. We carry Hudson-specific numbers rather than a single plains-wide assumption.
