Nelson was very knowledgeable and patient to explain the services and fees options which Ener Home Services could offer over the phone. At my home, he helped me identifying what are necessary for upgrade or for safety (e.g. complying with the fire code). As I had a limited budget, Nelson carefully studied my situation and made some very good suggestions to best use my budget. I compared 5 HVAC companies in GTA and finally decided to go with Ener Home Services, not only because of its reputation but also because it offered the best value for my money, plus Nelson’s attitude, enthusiasm and knowledge. At the installation day, the Technician Jimmy and the team were doing a great job. My home is a small townhouse and there was a limited space to move the equipment and work around to install them. However Jimmy and the team worked skillfully and completed the job with high quality. I’d like to strongly recommend this company to my friends who need to replace or install their furnace, water heater, or A/C.
