"Very accommodating and helpful with suggestions when it was noticed that the fan we purchased was defective..our installer came back in the afternoon to install the replacement fan. Check your purchases at Home Depot before you leave the store...our Hunter Fan was definitely returned by a previous customer and then put back on the shelf. The Company and installer handled the job very efficiently and professionally and we would highly recommend."

"Justin did great job, intalled the hookup and the transfer switch for the portable generator. Worked in freezing temperature outside. The only downside was that the install was postponed few times because he was waiting for the parts"
