Unlike rigid ducts, which are cut to length within a tolerance of 1 inch or less, it’s easy to cut a length of flexible duct that’s several feet longer than is needed to get from point A to point B [2A]. That creates slack in the duct, which reduces airflow for two reasons.

How do I know if I have a fresh air system?2021-03-20T20:40:25-07:00

Fresh Air Intake: If there’s a screen, it’s an intake. This is where the cool fresh air makes it’s way back to your HVAC equipment. You can test this by turning on the furnace and feeling the suction as it draws air in. Exhausts: If the vent has a flap, it’s an exhaust.

Is a fresh air intake necessary?2021-03-20T20:40:01-07:00

While not absolutely necessary, a properly insulated fresh-air intake duct attached to the return-air ducting for the heating system is a good idea to maintain healthy indoor air quality in your home.

Does furnace pull air from basement?2021-03-20T20:39:57-07:00

When the furnace fan comes on to push cold air through the duct, the hole you describe would pull more air from the basement than from the rooms. As the system tries to push more air into rooms that are not losing air, resistance would build. The result is you won’t get the cooling comfort you seek.

Can a dirty filter cause your furnace not to work?2021-03-20T20:36:32-07:00

Dirty air filters are often the culprit behind an inefficiently performing furnace. That’s because air filters trap dust, dirt and debris like hair, which over time can restrict or block vital air flow, overheating the heat exchanger and preventing your furnace from working as it should.

Can your furnace exhaust freeze?2021-03-20T00:58:19-07:00

In most cases, it was due to frozen condensate, which occurs when condensation and exhaust gases generated from the heating process are discharged outside via a vent pipe and freeze in the cold air. If ice continues to build up, the vent pipe can become blocked, causing the furnace to shut down.

What happens if furnace exhaust is blocked?2021-03-20T00:58:14-07:00

A blocked or damaged furnace flue prevents combustion gases from escaping outside. Instead these gases are released into your home. Once inside, they recirculate, and then carbon monoxide becomes part of the air taken in during the combustion process. This increases the amount of carbon monoxide present.

What is furnace exhaust?2021-03-20T00:58:08-07:00
