Refrigerant leak at a flare or coil connection
No cool air, or air that is barely cooler than the room
Heating and air conditioning service built around Johnstown
We keep licensed, background-checked technicians on the road in Johnstown and the surrounding 80534 service area, so a no-cool or no-heat call usually gets a same-visit fix rather than a return trip.
Homes in Weld County tend to be a mix of older builds with original ductwork and newer infill construction, which means airflow problems show up very differently from one street to the next.
If your system is over ten years old and you have had two repairs in the last two seasons, a replacement comparison is usually worth running even if the current unit still runs.

Johnstown80534 HVAC questions, answered
What does a new system cost in Johnstown?
A complete residential replacement in the 80534 area generally lands between $6,000 and $13,000 installed, depending on capacity, efficiency rating and how much ductwork has to be modified. We always perform a Manual J load calculation first, because an oversized unit costs more to buy and runs worse than a correctly sized one.
What causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In Johnstown we see algae and dust clogging drain lines constantly during June through August. It is a fast fix but ignoring it ends in ceiling damage.
Do you charge extra for nights, weekends or holidays?
No. Our pricing in Colorado is the same at 2am on a holiday as it is at 2pm on a Tuesday. Emergency calls are dispatched the same way as scheduled calls and carry no overtime premium.
Do you service commercial and light commercial properties?
Yes. Around Johnstown we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
What brands do you service in Johnstown?
All of them. Our 80534 technicians are trained on Heil, Goodman, Lennox, American Standard and essentially every other residential brand sold in Colorado, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
