Bumble Bee has serviced our A/C and gas furnace units for the past several years, and kept everything working efficiently. They've made minor repairs (new fan on our exterior condenser unit), and suggested minor improvements (re-taping the duct joints above the unit) which made a big difference in our overall comfort. We also had them install a Fujitsu mini-split heat pump unit in our home office space - they did an excellent job with the install (very neat and tidy), and it's performed perfectly. We wouldn't hesitate to recommend them to our friends and neighbors - and have done so happily. They always hire very nice/professional technicians too, so it's never a worry when they're over working on the house - which we very much appreciate.
