Dave Pugh's AllGood Home is a fairly small outfit, but they were very responsive, both initially in getting us the estimate, then in scheduling the work and showing up on schedule. We discussed various options, like extending the existing radiator system and just putting in central air conditioners, but after a lengthy discussion with Dave, we decided the simplest option was to replace the heat pumps with new, higher efficiency heat pumps. The first heat pump went in right away, no muss no fuss. The second one was delayed a day due to problems with the heat pump supplier, but they did what they could in prep work until they were able to secure the second heat pump. They were neat, efficient and professional. A few days later, one of the heat pump's digital thermostat began showing a fault and shutting off. Dave drove out on a Sunday afternoon to troubleshoot, eventually spending a good couple of hours before he was able to make it behave properly. Have had no troubles with it since then.
