Our Realtor recommended Richards when we moved in and they have been by the house 2x every year to inspect our furnace and air conditioning. We have only seen 2 different service folks - they have great tenure. Most amazingly, they have always been on time for the appointments. Amazingly on time compared to any other vendor we have worked with.
Several years ago we had them replace the aging AC and furnace and the job was completed on time and on budget.
