Pilot light or hot surface igniter failing repeatedly

Heating and air conditioning service built around Castle Rock
Most of the work we do in Castle Rock starts the same way: the system is running but the house is not comfortable. Before we replace anything, we measure airflow, static pressure and temperatures so you are paying for the actual fault.
In the 80109 area we see a lot of attic-mounted air handlers. Attic heat soak in summer and cold-soak in winter both shorten component life and make insulation checks part of a proper diagnosis.
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.

Castle Rock80109 HVAC questions, answered
Why is my furnace short cycling?
Short cycling in Castle Rock 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.
How quickly can a technician get to Castle Rock?
For the 80109 service area our target response time is 30-60 minutes from the moment dispatch confirms your address. Real-world timing depends on the day — the first sustained heat or cold snap of the season is always our busiest period — but we hold technicians locally specifically so that window is achievable rather than aspirational.
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 Castle Rock?
A complete residential replacement in the 80109 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.
How much does an HVAC service call cost in 80109?
A diagnostic visit in Castle Rock typically runs $75 to $150, and that fee is usually applied toward the repair if you approve the work. Repair prices are quoted as a flat rate before we start, so the number you approve is the number you pay regardless of how long the job takes.
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 Castle Rock 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.
