We have been customers for quite sometime after we moved into our house with an old furnace. We bought the annual service contract and have been absolutely delighted with them . We got an extra 10 years out of the old furnace. We had A1 install our new one like 6 years ago and then a new air conditioner as well. They are clean, quick and very professional.
Most recently we had to have sewer drain work done and unfortunately the drains were under the furnace. We called A1 to dismantle it, John was here right on time and explained the do/not do with the furnace off for our safety while it was pulled apart. After the drain work was complete he came back to reassemble a few days later - as John was here he arranged to do our annual service call for us as well, which was really convenient.
Every interaction we have had has been great, they are thorough and helpful and clearly have our best interest. I highly recommend them!!
