Even a high-quality furnace can underperform, or pose safety risks, if it wasn't installed correctly. Old Glory Air Conditioning and Heating helps Arlington area homeowners recognize warning signs that may indicate installation issues with a relatively new heating system.
If your new furnace never seems to heat your home evenly, even shortly after installation, this can indicate improper sizing for your home or ductwork connections that weren't properly configured during the installation process.
A properly installed, appropriately sized furnace should provide efficient heating in line with its rated efficiency. If your energy bills seem unexpectedly high following a new furnace installation, this can point to sizing issues or improper setup affecting the system's actual performance.
A new furnace that turns on and off more frequently than expected, rather than completing full heating cycles, can indicate an oversized system or improper installation, both of which place unnecessary strain on the equipment.
While some initial noise is normal as a new system settles in, persistent unusual sounds, rattling, banging, or excessive vibration, can indicate improper mounting, loose connections, or other installation issues that weren't properly addressed.
If certain vents provide noticeably weaker airflow than others immediately following installation, this can indicate ductwork connections that weren't properly sealed or connected during the installation process.
While a brief burning smell during initial startup is normal, a persistent burning or unusual odor that doesn't resolve can indicate an installation issue that needs prompt professional attention.
For gas furnaces, any activation of a carbon monoxide detector following a new installation is a serious safety concern that requires immediate attention, as it can indicate improper venting or combustion issues stemming from the installation.
Many installation issues can be traced back to inexperienced or rushed installation work. Choosing a licensed, experienced HVAC company for your furnace installation significantly reduces the likelihood of encountering these problems in the first place.
If you're noticing any of these warning signs following a recent furnace installation, it's important to have the system inspected promptly, ideally by a qualified technician who can identify whether installation errors are contributing to the problem.
