Frequently Asked Questions — Heavy Metal HVAC LLC

At Heavy Metal HVAC LLC, we take pride in providing top-quality heating and cooling services throughout Marion and Polk County, Oregon. Below you’ll find answers to some of the most common questions our customers ask about HVAC systems, maintenance, and installation.

General HVAC Questions

  • What does HVAC stand for?

    HVAC stands for Heating, Ventilation, and Air Conditioning. It refers to the systems that keep your home or business comfortable year-round.

  • How often should I have my HVAC system serviced?

    We recommend having your system serviced twice a year — once in the spring before cooling season and once in the fall before heating season. Regular maintenance helps prevent costly repairs and improves system efficiency.

  • How long should my HVAC system last?

    Most systems last 10–15 years with proper care. Oregon’s mild climate can help extend system life if maintenance is kept up.

  • What are signs I might need HVAC repair or replacement?

    Watch for uneven temperatures, higher utility bills, strange noises, or reduced airflow. If your system is over 10 years old and needs frequent repairs, it may be time to replace it.

Heating Systems (Gas Furnaces & Heat Pumps)

  • Why is my furnace blowing cold air?

    This could be caused by a dirty flame sensor, clogged air filter, or a thermostat issue. Our technicians can diagnose and fix the problem quickly.

  • What’s the difference between a gas furnace and a heat pump?

    A gas furnace burns natural gas or propane to create heat, while a heat pump transfers heat from the outside air into your home. Heat pumps are very efficient in Oregon’s climate.


  • How can I lower my heating bills?

    Regular maintenance, using a programmable thermostat, sealing ducts, and upgrading to a high-efficiency furnace or heat pump can all reduce your energy costs.

Cooling Systems (Heat Pumps, Ductless Mini Splits & Commercial Package Units)

  • Why isn’t my air conditioner or heat pump cooling properly?

    Low refrigerant, a dirty filter, or compressor issues are common culprits. We’ll run a full system check to find and fix the cause.

  • How often should I replace my air filter?

    Replace filters every 1–3 months depending on your filter type and indoor air quality. Clean filters improve performance and air quality.

  • What are the benefits of a ductless mini split system?

    Mini splits offer zoned comfort, high efficiency, and easy installation without the need for ductwork — perfect for additions, garages, and older homes.

  • What size heat pump or air conditioner do I need?

    We perform a load calculation to determine the correct size for your home or building. This ensures optimal comfort and efficiency.

Maintenance & Service

  • What’s included in an HVAC tune-up?

    Our tune-ups include cleaning coils, checking refrigerant levels, tightening electrical connections, testing components, and verifying overall system efficiency.

  • Do you offer maintenance plans?

    Yes! Heavy Metal HVAC offers annual service plans that include seasonal tune-ups, priority scheduling, and discounts on repairs — helping you keep your system running at its best all year long.

  • Can I do any maintenance myself?

    You can replace filters, keep outdoor units free of debris, and check thermostat batteries. Leave electrical or refrigerant work to licensed professionals like us.


Installation & Replacement

  • How long does a new HVAC installation take?

    Most residential installations are completed in one or two days. Commercial or more complex systems may take a little longer.

  • Do you offer free estimates for new installations?

    Yes — we provide free in-home and on-site estimates for all new system installations, including gas furnaces, heat pumps, mini splits, and commercial units.

  • Are rebates or financing options available?

    Yes! Many Oregon utility providers offer rebates for energy-efficient upgrades, and we also offer financing options (on approved credit).

Energy Efficiency & Air Quality

  • How can I improve my system’s efficiency?

    Regular service, proper insulation, sealing ductwork, and upgrading to ENERGY STAR® equipment all make a big difference.

  • Do you offer indoor air quality solutions?

    Yes — we can install air purifiers, high-efficiency filters, UV lights, and humidifiers to improve your home’s air quality.

  • What is a SEER rating?

    SEER (Seasonal Energy Efficiency Ratio) measures cooling efficiency — the higher the SEER, the more energy-efficient your system.

Service & Warranty

  • Do you offer emergency HVAC repair?

    Yes, Heavy Metal HVAC provides 24/7 emergency repair service for both residential and commercial customers in Marion and Polk County.

  • Are your technicians licensed and insured?

    Absolutely. All of our technicians are licensed, certified, and insured, giving you peace of mind on every job.
