Most residential AC installations take one full day for a standard replacement. If you’re upgrading from window units to central air, or if electrical work is needed, it might take two days. The timeline depends on your home’s specific requirements, like ductwork modifications or electrical panel upgrades. During the initial assessment, you’ll get a clear timeline so you can plan accordingly. Complex installations involving major ductwork changes or multiple zones can take longer, but you’ll know this upfront.
AC sizing depends on several factors beyond just square footage. Your home’s insulation, window placement, ceiling height, and local climate all matter. A proper load calculation considers these variables to determine the right capacity. Oversized units cycle on and off too frequently, wasting energy and failing to remove humidity. Undersized units run constantly and never achieve comfortable temperatures. Professional sizing ensures your system operates efficiently and keeps your home comfortable without wasting energy or money.
Yes, professional AC installation includes handling required permits and scheduling necessary inspections. Most municipalities in Norfolk County require permits for AC installation, especially when electrical work is involved. We pull these permits and ensure the work meets local building codes. We coordinate with local inspectors and handle any required follow-up. This protects you from potential issues down the road and ensures your installation is completely legal and up to code.
Absolutely. Homes without existing ductwork have several options for AC installation. Ductless mini-split systems are popular because they don’t require extensive ductwork and offer zone control for different areas. Traditional central air is also possible with new ductwork installation, though this is more involved. The best choice depends on your home’s layout, your budget, and your comfort preferences. During the assessment, you’ll see all viable options with honest pros and cons for each approach.
Installation day starts with protecting your home’s floors and furnishings. Our technicians will remove your old equipment and begin installing the new system, including indoor and outdoor units. You’ll hear some noise during the work, but we minimize disruption where possible. The process involves electrical connections, refrigerant line installation, and system testing. Once everything is connected and tested, we’ll walk you through operating your new system and clean up completely. Most installations are finished in one day.
Regular maintenance keeps your new AC system running efficiently and extends its lifespan. Change air filters every 1-3 months depending on usage and filter type. Keep the outdoor unit clear of debris, leaves, and vegetation. Schedule annual professional maintenance to check refrigerant levels, clean coils, and inspect electrical connections. Many homeowners join maintenance programs like our Dempsey Comfort Club for regular service reminders and priority scheduling. Proper maintenance prevents most major repairs and keeps your warranty valid.
