Central AC, heat pumps, and ductless splits.
Boulder summers are short but unforgiving — 95° afternoons followed by 50° nights. We size cooling equipment for that swing, not for the catalog. The result: a system that runs longer at lower stages and costs less to operate.
- Same-day AC repair and refrigerant service
- Two-stage and variable-speed AC installation
- Heat pump conversions (with Xcel rebates)
- Ductless mini-split design and install
- Smart thermostat setup with mobile control
Furnaces, boilers, and hybrid systems.
Three generations of work on Boulder furnaces means we've seen every brand, every age, and every failure mode. We don't guess — we measure manometer pressures, flame patterns, and combustion-gas readings before we say a word about cost.
- 24/7 emergency furnace repair
- High-efficiency furnace replacement (95%+ AFUE)
- Boiler service for hydronic & radiant systems
- Heat pump + furnace hybrid configurations
- Annual combustion safety inspections
Cleaner air for dry climates and smoke season.
Colorado's air is dry, dusty, and increasingly smoky. Comfort isn't just temperature — it's humidity, particulate, and ventilation. We install whole-home solutions that protect equipment, lungs, and woodwork.
- MERV-13+ media filtration
- UV-C in-duct sterilization
- Whole-home humidifiers (bypass and steam)
- ERV / HRV ventilation for tight homes
- Smoke-event protocol kits with HEPA
The cheapest hour you'll ever spend on your HVAC.
A spring tune-up before AC season and a fall tune-up before furnace season catches roughly 80% of the problems that turn into emergency calls. HearthGuard members pay $19–$59 a month and stop thinking about it.
- Spring AC tune-up (refrigerant, coils, capacitor)
- Fall furnace tune-up (heat exchanger, ignition, gas pressure)
- Priority scheduling for members
- Repair discounts of 10–20%
- Extended-warranty registration handled for you
