Air Conditioning

With our services, we at HARP offer upfront, affordable, no-surprise price quotes. We provide customers a plethora of different services, such as professional tune-ups and air conditioning system maintenance, AC unit replacement, as well as air conditioner repair, and emergency services.

Our team members also offer accessories that are ideal for spring and summer allergy season, such as our heating, ventilation, and air conditioning (HVAC) filters, which prevent particles — pollen, mold spores, animal dander, and dust — from infiltrating your home.


All of our work comes with a money-back guarantee, which means it’s essentially a risk-free purchase. Our team of technicians can install and replace heating systems, provide maintenance and tune-ups for boilers, heat pumps, and furnaces, offer emergency services for heaters, as well as fix heating systems on short notice.


Our HARP installations and repairs include comprehensive warranties, even for our plumbing services. Our factory-trained, certified plumbers provide services like water heater replacement and repair, sump pump maintenance, and drain clearing, as well as emergency services. Leaky bathroom faucet? Not a problem. Our plumbing system repair team can fix it.
