I recently had Always... come out to do a preventative maintenance on my furnace and to unstop a clogged drain.
I thought that the guy that came out was pretty knowledgeable, I would have asked him to do major repairs. The drain definitely works much better now and he even gave me some advice on what to do to keep it working better.
The preventative on the furnace really didn't seem like he did too much just clean the motor.
Some bad things: I really feel like I was overcharged, the service call alone is 70$ without doing a thing. They were supposed to return my call a day earlier than they did. Also they were supposed to get back to me with a quote for more work and they still haven't (a week later). Also the preventative furnace maintenance didn't even come with a new filter, this seems so basic to me, but maybe they never do.
I gave 3 stars because I feel they were competent, and could probably do any work. I will not be using them again.
