Our AC went out during a heatwave. Jim Leahy showed up 11AM sharp as promised and fixed our unit quickly for a great price.

I would not recommend this company. After leaving message and calling several times needing service finally someone answered and apologized for not returning the call saying they had been very busy. I was told I would be contacted when they were on there way later that day but never received a call they just showed up at the door. They found the boiler motor needed bushings and they would replace coupler . The home visit with nothing being fixed was $135.00 only thing physically done was a few squirts of oil in the boiler motor and a promise they would call me when parts were located. I never recieved

Jim Leahy's - owner service is exceptional and had exceeded my expectations. I placed call for service on Friday evening and he called me same night to check on the issue and gave me some tips on how to troubleshoot. Few people will do that..had many times called for service, him and and his staff are always very honest and helpful and his work is always top notch..highly recommend this business.
