Short cycling — on and off every few minutes

Heating and air conditioning service built around Littleton
We keep licensed, background-checked technicians on the road in Littleton and the surrounding 80166 service area, so a no-cool or no-heat call usually gets a same-visit fix rather than a return trip.
Homes in Arapahoe 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.

Littleton80166 HVAC questions, answered
How often should I change my filter in 80166?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Littleton with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.
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.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Littleton see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
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.
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 80166 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.
