Castle Pines is an upscale community south of Castle Rock with large custom homes, many exceeding 4,000 square feet, set among mature ponderosa pines at 6,200+ feet elevation.
Castle Pines' high elevation and pine tree surroundings create unique challenges — pine needle accumulation on outdoor AC units, wildfire smoke concerns, and extreme cold at elevation during winter storms.
Castle Pines homes are often large enough to need dual furnace systems — one for the main level and one for the upper floor. When one system fails, the other compensates by running overtime, which can lead to both systems failing in sequence if not caught early.
Castle Pines homeowners — the ponderosa pines around your home are beautiful but shed needles that accumulate on and inside your outdoor AC condenser. Schedule a professional condenser cleaning in late spring before cooling season begins.
