25 HVAC questions, answered plainly.

HVAC stands for Heating, Ventilation, and Air Conditioning, which covers the systems that regulate indoor comfort.

Experts recommend twice a year, once before summer and once before winter, to keep efficiency high and prevent breakdowns.

Common signs include uneven temperatures, strange noises, weak airflow, and rising energy bills.

With proper maintenance, most HVAC systems last 12 to 20 years.

Yes. Routine maintenance improves efficiency, prevents costly repairs, and lowers energy bills over the life of the system.

It depends on your location and needs. Options include furnaces, boilers, heat pumps, and radiant heating.

This may be caused by a clogged filter, a pilot light issue, or a thermostat problem.

Most filters should be replaced every one to three months, depending on usage and household factors like pets.

Yes. Heat pumps can both heat and cool, which makes them an energy efficient choice for the Oklahoma climate.

A furnace heats air and distributes it through ducts, while a boiler heats water and circulates steam or hot water.

Proper ventilation improves air quality, reduces allergens, and helps prevent mold growth.

They include exhaust, supply, balanced, and energy recovery ventilators, often called ERVs or HRVs.

Signs include stale air, condensation on windows, lingering odors, and high indoor humidity.

Yes. Clean, filtered ventilation reduces dust, pollen, and pollutants that trigger allergies.

Yes. Mechanical ventilation ensures consistent air exchange even when windows are closed.

At least once a year, ideally before the summer season begins.

Possible reasons include low refrigerant, dirty filters, blocked vents, or compressor issues.

Most AC units last 10 to 15 years with regular maintenance.

If it is over 12 years old, needs frequent repairs, or drives high energy bills, replacement is usually the better value.

No. Oversized units short cycle, which wastes energy and reduces comfort. Proper sizing is essential.

Replace filters regularly, schedule maintenance, seal ducts, and consider a programmable or smart thermostat.

Yes. Smart thermostats optimize heating and cooling and can save around 10 to 15 percent on energy bills.

Costs vary, but a new system typically ranges from about 5,000 to 12,000 dollars depending on size and type.

Yes. Air Factory offers financing, and we provide free estimates on standard work.

Yes. Modern systems with air purifiers, humidifiers, and ventilation upgrades noticeably improve indoor air quality.
