Air conditioning systems often show warning signs before failing completely. Contact Dalelis if you notice:
Dedham's housing ranges from historic homes in the Village and Precinct One to mid-century builds in Greenlodge and Oakdale. Many of the oldest homes were built without air conditioning, and adding cooling requires careful planning. Dalelis specializes in retrofitting ductless mini-splits into older colonials and installing central air in homes with existing ductwork.
In newer neighborhoods near Legacy Place and Route 1, homes typically have central air systems that are 15 to 25 years old. If your AC runs constantly without adequately cooling, or makes unusual noises, those are signs it needs professional diagnosis. We handle refrigerant recharges to full system replacements.
Dalelis is based in Norwood, roughly 5 miles south of Dedham Square, so we respond quickly for scheduled maintenance and emergency cooling calls alike.
Yes. We install ductless mini-split systems that provide cooling without tearing into walls or ceilings. It is one of the most popular AC upgrades we do in Dedham's historic neighborhoods.
Proper sizing depends on square footage, insulation, windows, and layout. We do a Manual J load calculation to recommend the right size for your specific home.
A central air replacement typically takes one day. New installations without existing ductwork or multi-zone mini-splits may take two days.
We install and service Carrier, Lennox, Goodman, Rheem, Mitsubishi, and Comfort-Aire. We recommend based on your home's needs, not brand loyalty.
