I would never recommend this company D DOWLER.My home warranty company contacted them they came out checked furnace said it was pressure switch.I sent email to home warranty company which they received since they had been dispatched. I got email that night saying they canceled my service call as my negativity toward warranty company hurt their feelings.I called to explain guy was really rude and said call Dawson Heating and Air since they did such a good job for me first time.Worked out for the best for me as they misdiagnosed the problem anyways.I would recommend Dawson .
