The Littleton80123 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.
No cool air, or air that is barely cooler than the room
Outdoor condenser humming but the fan not turning
Musty or burnt smell the first time the system runs
Short cycling — on and off every few minutes
Loud banging on start-up (compressor slugging)
One or two rooms that never reach the set temperature
Heating and air conditioning service built around Littleton
Serving Littleton and the wider Jefferson County area, our crews carry the common failure parts on the truck — capacitors, contactors, igniters, flame sensors, motors and filters — so the first visit is usually the last one.
A large share of the equipment we service in Littleton was installed by a builder to a minimum spec. That usually means an undersized return, a cheap filter rack and a condenser sitting close to a wall.
Heating season here is October through April. A pre-season inspection catches cracked heat exchangers and failing igniters before the first real cold snap.

Littleton80123 HVAC questions, answered
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.
What brands do you service in Littleton?
All of them. Our 80123 technicians are trained on Trane, Goodman, American Standard, Rheem 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.
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.
What does a new system cost in Littleton?
A complete residential replacement in the 80123 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.
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in Colorado, particularly in older homes without existing ductwork. We service indoor heads, clean filters and drain lines, check line-set insulation and diagnose communication faults between heads and the outdoor unit.
Do you service commercial and light commercial properties?
Yes. Around Littleton 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.
