Edward arrived promptly on time, was extremely courteous and knowledgeable. He diagnosed my dead a/c quickly and I decided it would be cost-prohibitive to repair and will arrange for a replacement unit instead. Give Edward a pat on the back for doing his job well and being a total professional.
Alex came to my property and installed a fresh air intake vent and replaced an old exhaust vent on my furnace. He was professional, courteous, and very informative in explaining his work. completed the work quickly and everything looks great. He certainly represents Walley's as a top company to use. I will certainly use them for future jobs.
Bryan arrived on time and serviced/inspected my hot air furnace, central air conditioner, and a spit-ductless A/C unit. He was courteous, professional, efficient, and advised me of what he was doing. All work was completed in a timely fashion. Bryan should be commended for his professionalism.

Needed my AC unit checked, the entire process from booking to arrival was easy and seamless. The automated updates for arrival time were great. The technical did a great job and explained everything.

What a terrible experience with Walley’s Heating and Air Conditioning. We were given a service window of 1:00–4:00 PM, but the technician didn’t arrive until 5:56 PM. We tried to be understanding because these are some of the first hot days of the season and we know HVAC companies are busy.
After spending about an hour here, the technician told us he could not get our outside condenser to turn on and claimed that multiple parts of our professionally installed five-year-old system needed to be replaced — possibly even the entire unit.
After he left, my husband spent less than 10 minutes troubleshooting the issue himself and got the outside unit running simply by replacing the relay.
Very disappointing experience, especially after being told we might need thousands of dollars in repairs for what turned out to be a simple fix.

I can't say enough great things about this company and serviceperson Jim. Courteous prompt service. Quick responses. I am a new resident in this state and had no prior connection to any heating service here. Not only was each employee I spoke with wonderful but they helped me quickly and efficiently. I am now a customer forever.

The service is good, but the charge is too high.

Truck driver almost crashed into me in Derry when trying to go around a mail truck in the other lane. Just because you can’t get around someone in your lane doesn’t mean you can swerve into the other one and almost hit someone else. Had I not moved to the right off the road they would’ve crashed into my vehicle head on. Train your employees better bro

This was our first experience using Walley's. Their service technician Bryan was very knowledgeable and explained the required repairs and cost to complete them. We are very satisfied with their service and highly recommend them.
