iAbout service coverage
Coverage is as the business describes it, cross-checked against where its recent documented work is. A company will often travel beyond the areas listed here for a large job and decline a small one at the same distance, so confirm your address before scheduling.
About Cottam Heating & Air Conditioning
City Island is a small fishing-village corner of the Bronx, reached by a single bridge from Pelham Bay Park. Cottam Heating & Air Conditioning has its base on Fordham Street there, and its website says the family-owned company has been in business since 1984. Its red service trucks are a familiar sight across the Bronx and lower Westchester, where it lists towns such as New Rochelle, Pelham, Larchmont, Mamaroneck, Mount Vernon, Yonkers and Port Chester.
The service list is complete for a residential heating and cooling company. It covers air conditioning repair, installation and maintenance, ductless systems, heat pumps, furnaces, boilers, radiant heating, duct repair and sealing, and indoor air quality. The company also does commercial air conditioning. It describes itself as a Mitsubishi Electric Diamond Elite Contractor, and it says its trucks are fully stocked so more repairs can be finished on the first visit.
Loyalty is the main theme in the reviews. One customer has used Cottam for years across two homes and a family member's property. Another has been on a maintenance plan since about 2013, with twice-yearly service, and turned to Cottam again when a bigger job came up. A homeowner doing a larger renovation had a heat pump and two mini-splits installed after a referral from their general contractor, and was pleased with the result. Technicians mentioned include Jim, Rob, Tom, George and Hector.
There is one critical review worth noting. A customer was told their three-year-old water heater should be replaced, declined, and then had it fail again a few months later. They questioned whether the first recommendation was right. It is a reminder to ask for the reason behind any replacement advice.
Cottam lists 24-hour availability and 24/7 emergency service. The website offers a satisfaction guarantee and competitive financing on installations, but it does not advertise free estimates or publish license numbers.
Who it suits: Bronx and Westchester homeowners who want a long-term HVAC partner with a maintenance plan, and anyone planning a Mitsubishi heat pump or mini-split project. Who it suits less well: Brooklyn and Staten Island residents, who are outside its usual area.
Before booking, ask what the maintenance plan includes, whether there is a service call fee, and for the specific reason behind any replacement recommendation.
