The Nunn80648 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.
Loud banging on start-up (compressor slugging)
One or two rooms that never reach the set temperature
Heat pump stuck blowing cold air in heating mode
Dead or bulging run capacitor on the condenser
No cool air, or air that is barely cooler than the room
Pilot light or hot surface igniter failing repeatedly
Heating and air conditioning service built around Nunn
Dry air, wide day-to-night swings and high altitude all change how combustion and refrigerant systems behave. Across the 80648 area that translates into a steady stream of failed capacitors, clogged filters, dying blower motors and refrigerant leaks — most of which we can diagnose and repair in one visit.
Around Nunn, condensate drainage is a recurring fault. Blocked drains and failed float switches cause more water damage claims here than actual refrigerant failures do.
Because Colorado runs high-efficiency gas furnaces with central air, the transition between seasons is when we see the most emergency calls — equipment that sat unused for months.

Nunn80648 HVAC questions, answered
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 Nunn 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.
Why is my furnace short cycling?
Short cycling in Nunn most often comes from a restricted airflow path — a loaded filter, a closed register, an undersized return — or from an oversized unit. It can also be a failing flame sensor or a pressure switch fault. We measure static pressure and temperature rise before concluding anything, because guessing at this one is expensive.
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.
Are your technicians licensed and insured?
Every technician dispatched into Nunn is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
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 offer maintenance plans?
We do. A two-visit plan in Colorado covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.
