Any mistake during furnace installation can jeopardize your safety and lead to a fire or carbon monoxide leak. Temperature fluctuations, humidity issues, and noise are also possible. At the very least, a poorly installed furnace will run inefficiently and increase energy costs, require more repairs, and may not last as long. Therefore, furnace replacement is not a DIY job. The following mistakes can create significant safety hazards:
1. Hiring an Inexperienced Contractor
Finding an HVAC installer that is licensed, certified, and insured is critical. Make sure they have several years of experience installing furnaces. An inexperienced contractor or a handyman doesn’t likely have the knowledge required to complete the job and avoid costly mistakes and safety hazards. Always check a professional’s reviews and background before hiring them; also, avoid going for the cheapest bid.
2. Selecting a Furnace That’s the Wrong Size
One of the biggest furnace installation mistakes is choosing one that’s too big or too small for your home. Bigger is never better when it comes to heating systems. A technician must perform the proper calculations to determine the right size and capacity for any HVAC unit, whether it’s a furnace or air conditioner.
Don’t automatically assume your old furnace is the right size. It may not be. The load calculation is an important part of the process and ensures your heating unit will work efficiently and operating costs will be kept in check.
3. Poor Ductwork Design and Installation
For your heating system to be safe and effective, your duct system must be properly designed. It will then allow heated air to get to where it’s required. Improperly sized ductwork won’t match the unit’s output capacity. And old ductwork may have leaks that can impact efficiency.
To avoid efficiency problems, heat loss, and airflow problems, have a professional evaluate your ductwork. They’ll ensure it’s properly sized, sealed, and insulated. An experienced contractor will also ensure a seamless installation of ducts, supply and return vents, ceiling diffusers, etc.
4. Failing to Meet Ventilation Requirements
Poor ventilation or a lack thereof can cause carbon monoxide to build up. This can be a deadly situation for your household. Intake vents, exhaust pipes, flues, dampers, and related components must be correctly installed to avoid a buildup of toxic gases.
5. Installing the Furnace in the Wrong Place
During the furnace installation process, the contractor should identify a spot where the unit can be properly ventilated and they can access it for maintenance and repairs. Registers and return grills must also be installed where there are no obstructions. Meanwhile, placing exhaust vents where they’re unlikely to get blocked improves safety, and the outdoor unit your furnace is connected to should be in an open area where vegetation, leaves, branches, and foliage won’t interfere with its performance.
6. Incorrect Drain System Design
A furnace generates moisture and condensation as it heats the air, which must be drained away. If the drainage system is poorly designed, there’s a risk of leaks and water damage to your home. Water can also back up in pipes and freeze when it’s cold outside, potentially leading to HVAC system failure. Your safety can be jeopardized by mold and indoor air quality issues as well.
7. Installing the Thermostat Incorrectly
Furnace installation involves installing several components, including the thermostat. If it’s not correctly placed and connected, it will have difficulty communicating with your heating system, resulting in poor temperature control that can leave your home dangerously cold or hot. A professional will properly connect the thermostat, calibrate it, and perform tests to ensure the system is capable of effective temperature control.
8. Forgetting to Register the Warranty
The manufacturer’s warranty must be registered for you to take advantage of it if there’s a defect or repair issue. Furnace repairs are often expensive, so it’s important to have warranty coverage. Also, follow all maintenance guidelines (including professional tune-ups and installation) to keep your furnace in peak condition and prevent voiding the warranty.
