Diaco's HVAC is a Worcester HVAC company that Angi says has five years of experience, with services centered on central air-conditioning installation, heat pumps, and central air cleaners. That is a focused set of heating-and-cooling jobs for homeowners planning an installation or replacement. The written customer history is very small: one Angi review, posted in 2023, rated the company two stars. The homeowner said a four-day job was not completed as promised, with missed appointments and calls that were not returned. That account is old, but it is specific enough to make scheduling and follow-through the first things to clarify. Diaco's HVAC may fit a homeowner looking for the listed installation work, but confirm the scope, completion date, arrival windows, and communication plan before booking. Ask what happens if the job runs past the quoted timeline, and get those terms in writing.
They told me they would do the job for 4 days and they could not do it. I am trying to work with them but now they are telling me they have a job and it is like I am begging them to do my job. They do not show up or call me and when they say they are going to show up they do not come.
