Anthony was very professional and knowledgeable.
Punctual, professional and thorough. Kept me informed on what he was doing. Did an inspection and tune up on my boiler. Ready for the cold weather!
Prompt and reliable. Good communicator. Clearly stated what he was going to do and later recapped the results of his work.
The technician, Anthony, was very pleasant and thorough.
Great service! Mr. Powers always does a great job!

Howald technicians are always professional. We’ve used them for about 8 years for a new HVAC and then semi-annual maintenance, which has been so helpful.

Daniel did a great job!
Our malfunction was hard to figure out. James clearly knew his stuff and dug deep to try to find a simple and inexpensive solution. In the end though we’ll have to spend some money on a motor replacement. But we can do that confident that had it been something simple, James would have found it. We do not worry that…
