The problem with most "pros"? Too many bad habits. \nIt's easy to get swept away in the day to day monotony, even for those that call themselves "pros". When it comes to hiring a heating and cooling technician, nobody wants to deal with being treated like a sale rather than a person, the use of scare tactics instead of education, or someone who just wants to get to job done quickly instead of correctly. \nAll our HVAC pros go through 5 years of HVAC schooling, for a total of 10,000 hours of on-the-job training. And it's not just technical training either; it's training that focuses on you, on making you feel comfortable every step of the way. We will roll out the red carpet for you, both figuratively and literally. \nRed Carpet Treatment \nDuring every visit to a home, we lay out an actual red carpet to prevent any additional mess. But what may be even more important than just protecting your home is making sure you feel like you've received the best in customer service.

"The install could not have gone better. The technician was at my home at exactly the time given. My water heater is in a carpeted hall way and the technician was careful and considerate to ensure that carpet was not damaged. The installation took about 2 hours and when done, I would never have known the technician was in the home except that I now had hot water."

"A regular furnace and air conditioning maintenance check on Wednesday, January 13 revealed that the heat exchanger was failing on our 17-year-old furnace.  There were other problems as well.  The condition was unsafe and we decided to replace the furnace and the air conditioning unit which had been installed at the same time, to take advantage of financial incentives and improved efficiency.  We've dealt with Homer Nine for many years, and they were willing to install the furnace immediately, on an emergency basis.  The day after the furnace check, January 14, they customized the sheet metal ductwork and installed a new furnace.  They came back the following Monday, January 18, they returned and installed a new air conditioning unit.  On every occasion, they were punctual and courteous, and described what they were doing.  They cleaned up completely.  This is why we've dealt with them exclusively for many years - a very professional company which treats its customers very well.

"Dylan and Nate were excellent across the board! They were super nice, they thoroughly explained all relevant points, and they picked up our 75 gallon water tank within hours of it being available to pick up and installed it the same day. And the job was done with precision. It could not have been a better experience from start to finish! Thank you Dylan and Nate for everything!! It is truly appreciated!"
