Frequently Asked Questions

General HVAC

  • HVAC stands for Heating, Ventilation, and Air Conditioning. It covers all systems that regulate indoor temperature, humidity, and airflow — including furnaces, air conditioning units, ductwork, vents, and filters.

  • Twice a year — once in the spring before cooling season and once in the fall before heating season. Bi-annual tune-ups keep your system efficient, extend its lifespan, and catch small issues before they become expensive repairs.

  • Rising energy bills without a change in usage, uneven temperatures or hot/cold spots, strange noises (banging, clanking, humming), frequent cycling, system age of 15 years or more, poor airflow, or an unexplained increase in indoor humidity.

  • Every 1 to 3 months for most homes. If you have pets, allergies, or smokers in the home, change it more frequently. A clogged filter restricts airflow and makes your system work harder than it needs to.

  • Consider the repair cost alongside the age and efficiency of the system. A useful rule of thumb: if repairs will cost 50% or more of what a replacement would cost and the system is older or inefficient, replacement usually makes more financial sense long-term.

  • Yes. We offer 24/7 emergency HVAC repair. Call us anytime at 303-919-9292 and a qualified technician will respond as quickly as possible.

Heating and Furnace

  • 15 to 20 years with proper maintenance. Regular filter changes and annual tune-ups go a long way toward reaching that upper range.

  • When the system is 15 years or older, has frequent breakdowns, has jumped significantly in energy costs, or when the repair estimate is 50% or more of replacement cost.

  • Different sounds point to different issues. Rattling usually means loose parts. Buzzing suggests an electrical problem. Whistling can indicate dirty ducts or a clogged filter. Banging at startup often points to delayed ignition. If you hear something new, shut the system off and call for an inspection.

  • Check and replace the air filter, test your thermostat on heat mode, vacuum vents, remove clutter around the furnace, verify smoke and carbon monoxide detectors are working, and schedule a fall tune-up.

Air Conditioning

  • Common causes include a clogged filter, incorrect thermostat settings, a refrigerant leak, a frozen evaporator coil, or a failing compressor. Start with the filter and thermostat. If nothing obvious stands out, turn the system off and call for a diagnostic.

  • The unit is 10 years or older, requires frequent repairs, cools inconsistently, has weak airflow, cycles more than it should, or your energy bills have increased without explanation.

  • Yes. A spring tune-up ensures your system is ready before the heat arrives. A technician will check refrigerant levels, clear condensate drains, inspect coils and wiring, and verify overall performance.

  • Why do some rooms stay warmer than others?

Hybrid Systems

  • A hybrid system, also called a dual-fuel system, pairs an electric heat pump with a gas furnace. It automatically switches between the two based on outdoor temperature — using the heat pump in mild weather and the furnace when it gets cold enough that gas heat becomes more efficient.

  • The upfront cost is higher than a conventional system, but the monthly energy savings are real and ongoing. Many homeowners recover the difference over time, especially in Colorado where both heating and cooling loads are significant.

Tankless Water Heaters

  • A tankless unit heats water on demand rather than keeping a large tank hot around the clock. This eliminates standby energy losses and means you never run out of hot water. The tradeoff is a higher upfront cost.

  • Yes. With proper maintenance, a tankless water heater typically lasts 20 years or more, compared to 8 to 12 years for a conventional tank unit.

Ductless Mini-Splits

  • A heating and cooling system that works without ductwork. It has an outdoor compressor and one or more indoor air handlers. Each zone can be controlled independently, making mini-splits ideal for room additions, garages, or spaces your central system doesn't reach well.

  • Yes. Dual-function mini-splits run on a heat pump and output warm or cool air depending on the season.

Indoor Air Quality

  • Common signs include frequent allergy symptoms indoors, noticeable dust buildup, unexplained odors, humidity swings, or a stale smell in rooms with limited airflow. Colorado's dry climate makes humidity control especially important.

  • Yes, particularly HEPA-level models. They work best alongside proper ventilation rather than as a replacement for it. For whole-home coverage, an in-duct air purifier integrated with your HVAC system is more effective than a standalone unit.

Load Calculations

  • The industry-standard method for determining how much heating and cooling capacity your home actually needs, measured in BTUs. It accounts for insulation, window size and placement, square footage, and local climate. Go Green includes a Manual J calculation with every installation at no extra charge.

  • An oversized system short-cycles, wasting energy and wearing out components early. An undersized system runs constantly and still can't keep up. A properly sized system heats and cools evenly, runs efficiently, and lasts longer.

Emergency Repairs

  • Any situation with an immediate impact on your health, safety, or property — including total loss of heating in winter, loss of cooling in extreme heat, a suspected gas leak, electrical problems, or flooding from a condensate line.

  • After-hours service typically costs more due to overtime and priority scheduling. We provide upfront pricing wherever possible and will never surprise you with hidden charges.

  • Turn the system off, close blinds to block heat gain or retain warmth, check thermostat batteries and the circuit breaker, use a fan or space heater if safe to do so, and avoid DIY repairs on gas or electrical components. Call us at 303-919-9292 and we'll get someone out as fast as possible.
