Most residential furnace installations take 4-8 hours, depending on your home’s setup and whether any ductwork modifications are needed. If you’re replacing an existing furnace with similar specifications, the job usually goes faster. However, if you’re upgrading to a different type of system or need electrical work, it might take a full day. We’ll give you a realistic timeline upfront so you can plan accordingly. We work efficiently but never rush the important details like proper connections and safety testing.
Furnace sizing depends on your home’s square footage, insulation quality, window efficiency, and ceiling height – not just the size of your old unit. A proper heat load calculation takes into account Rochester’s climate and your specific home characteristics. Many homeowners are surprised to learn their old furnace was oversized, which actually reduces efficiency and comfort. An oversized unit cycles on and off too frequently, while an undersized unit can’t keep up on the coldest days. Professional sizing ensures optimal performance and energy efficiency.
Yes, we handle all permit applications and coordinate required inspections with local authorities. This includes gas line permits if modifications are needed and general HVAC permits for the installation. We’re familiar with Rochester and Plymouth County requirements, so there are no delays or complications with paperwork. The inspection process ensures your installation meets all safety codes and manufacturer specifications. You don’t need to take time off work to meet inspectors – we coordinate everything as part of the installation service.
The old furnace gets disconnected safely and removed from your home as part of the installation service. This includes properly capping gas lines, disconnecting electrical connections, and removing the unit from your basement or utility area. We dispose of the old equipment responsibly according to local regulations. If your old furnace contains materials that require special handling, we take care of that too. The work area gets cleaned up, so you’re not left with debris or an old furnace taking up space in your basement.
If your furnace is over 15 years old and requiring frequent repairs, replacement usually makes more financial sense than continuing to fix an aging system. Other signs include uneven heating throughout your home, yellow flames instead of blue, strange noises, or utility bills that keep climbing despite similar usage. A system that can’t maintain comfortable temperatures or cycles on and off constantly is telling you it’s struggling. During an assessment, we’ll give you an honest evaluation of whether repair or replacement makes more sense for your situation and budget.
New furnaces typically come with manufacturer warranties ranging from 10-20 years on major components, with shorter coverage on parts like filters and controls. The installation work itself is backed by a separate workmanship warranty that covers any issues related to the installation process. Extended warranty options are often available for additional protection. We’ll explain exactly what’s covered under your specific equipment warranty and help you understand any registration requirements. Proper installation and regular maintenance through programs like the Dempsey Comfort Club help ensure warranty coverage remains valid.
