Signs you need heater repair
Not sure whether it’s time to call? These red flags say don’t wait: cold spots in lived-in rooms; not blowing warm air or weak airflow from vents; short cycling (on/off) or new strange noises; a sudden spike in energy bills; or any burner/ignition or electrical odor. If startup is delayed or your thermostat can’t hold temperature, a targeted repair can often restore performance quickly.

Heating system installation
Ready to upgrade to energy-efficient heating without running new ducts or changing your fuel type? We design and install heat pumps, ductless mini-splits, and electric heaters that deliver quiet comfort and precise control—ideal for remodels, additions, and homes aiming for lower utility bills. Every project starts with thoughtful system design so your new equipment matches your space, usage, and goals.
Professional sizing & load calculations
Comfort isn’t guesswork. We perform Manual J load calculation to right-size your system, using heat loss analysis, airflow balancing, and ductwork assessment. Proper sizing helps prevent short cycling, reduces noise, and extends equipment life while maintaining even temperatures.
Post-installation system check & warranty support
Install day ends with a full startup and commissioning: control calibration, performance verification, and a documented QA/commissioning checklist. We register equipment for manufacturer warranty coverage and show you how to use your new controls for best efficiency and comfort.

Heating maintenance & service plans
Proactive care keeps little issues from becoming big bills. Our tiered **HVAC maintenance plans—Silver, Gold, and Platinum—**include seasonal inspections, filter changes, deep cleanings, and performance testing (including combustion analysis where applicable). The result? A quieter system, steadier temps, and lower energy spend year-round.
Anual heating maintenance
With yearly maintenance, small issues never get the chance to become emergencies. We set a schedule, perform safety checks, deep-clean the system, lubricate moving parts, replace filters, and document readings so you have a clear record. The goal is the same every visit: safer operation, fewer surprises, lower costs.

Frequently Asked Questions
How often should I schedule heating maintenance?
Most manufacturers recommend annual heating service. In Colorado’s climate, a fall tune-up prepares your system for heavy use, while homes with heat pumps often benefit from a spring check as well. We’ll tailor the preventive schedule to your usage and system type.
What are common signs I need heater repair?
Watch for uneven heating, new noises, short cycling, odors at startup, or higher utility bills. Airflow issues or thermostat problems can also point to underlying faults. The sooner you call, the simpler—and usually more cost-effective—the fix.
Do you offer heating maintenance plans?
Yes—our plan tiers (Silver/Gold/Platinum) include tune-ups, priority response, and discounts on repairs. You’ll also receive reminders so you never miss seasonal service. Ask us which level fits your home and budget best.
