Highly recommend Leeda Air Systems for anyone needing HVAC or hot water tank service. Our old hot water tank failed and flooded the basement, and Lee came in on short notice to make sure we weren't without hot water for long. The new tank was installed quickly, at a great price, and Lee handled the whole job with real professionalism. Great experience from start to finish — will be calling them again for any future HVAC needs.
