Most residential AC installations take between 4-8 hours, depending on your home’s specific requirements. Straightforward replacements where existing ductwork is in good condition typically finish faster. If we need to modify electrical connections, update ductwork, or work around unique architectural features common in Norfolk County homes, it may take longer. We’ll give you a realistic timeline during our initial assessment and keep you informed if anything changes during installation.
Proper sizing requires a detailed load calculation that factors in your home’s square footage, insulation levels, window placement, ceiling height, and local climate conditions. Many homeowners assume bigger is better, but oversized systems actually cool poorly and waste energy. Undersized systems can’t keep up on hot days. We perform Manual J load calculations to determine the exact capacity your home needs for efficient, comfortable cooling throughout the summer months.
Yes, we handle all necessary permits for AC installation in Medfield and throughout Norfolk County. We’re familiar with local building codes and inspection requirements, so you don’t need to worry about compliance issues. Our installations meet or exceed Massachusetts building standards, and we coordinate with local inspectors when required. This ensures your installation is done legally and safely, protecting both your home and your investment.
Absolutely. Many older Norfolk County homes weren’t built with central air conditioning, but that doesn’t mean you can’t have it. We can install new ductwork, recommend ductless mini-split systems, or explore hybrid solutions that work with your home’s existing heating system. Each situation is different, so we evaluate your specific layout, basement or attic access, and cooling priorities to recommend the best approach for your home and budget.
All equipment comes with manufacturer warranties, and our installation work is guaranteed. If something isn’t working properly, we’ll return to diagnose and fix the issue. As a Dempsey Energy customer, you have access to our ongoing service team and can join our Dempsey Comfort Club for priority scheduling and maintenance benefits. We’re not going anywhere – we’ve built our reputation in this community by standing behind our work and taking care of our customers long-term.
Spring and early summer are ideal for planned AC installations, before the peak cooling season hits Norfolk County. You’ll have more scheduling flexibility, and we can take time to ensure everything is perfect before you really need the system. However, we handle emergency replacements year-round when systems fail unexpectedly. If your current system is struggling or you’re concerned about reliability, don’t wait until it fails completely during a heat wave to consider replacement.
