To install a furnace in a house with a crawl space, follow these steps:

Assess the Crawl Space: Before installing the furnace, inspect the crawl space for any signs of moisture or damage. Ensure proper ventilation by checking and, if necessary, installing crawl space vents to promote airflow and prevent moisture buildup.

Prepare the Area: Clear the crawl space of any debris or obstacles to create a suitable workspace for installation. Ensure there is adequate space for the furnace unit and access for maintenance.

Install Ductwork: If the house doesn't already have ductwork in the crawl space, install it to connect the furnace to the rest of the HVAC system. Seal all duct joints properly to prevent air leaks.

Position the Furnace: Choose a suitable location for the furnace within the crawl space, considering factors such as accessibility, clearance requirements, and proximity to existing ductwork.

Secure the Furnace: Once the furnace is in position, securely mount it according to the manufacturer's instructions. Ensure it is level and stable to prevent any movement or vibration during operation.

Connect Utilities: Connect the furnace to the power supply and fuel source, whether it's gas, oil, or electricity. Follow local building codes and safety guidelines when making these connections.

Test and Commission: After installation, test the furnace to ensure it functions correctly. Check for any leaks, unusual noises, or malfunctions. Once everything is in working order, commission the furnace for regular use.

By following these steps and ensuring proper ventilation with crawl space vents, you can successfully install a furnace in a house with a crawl space while maintaining a safe and efficient HVAC system.

Should a crawl space have plactic sheeting on the ground?

Absolutely. Moisture from the ground (or even concrete floor as water seeps through) will rise up and saturate the crawl space area with moisture. Anything organic in the space- including wooden beams and insulation- runs the risk of growing mold and rot, eventually affecting the structural integrity of the home and overall healthiness. Additionally, termites can enter and devour the moist wood, and mold spores will rise into your home. (This is much more common than many people think- warm air exits out of the upper levels and cool air is sucked up through the crawl space). Unsealed crawl spaces will also bring humidity into the house and be a perfect place for rodents to live and die in. Definitely put something down. And if you have a vented crawl space, you should look into sealing those vents if local housing codes allow for it.
