Do NOT hire them for extended maintenance plan. When the AC GUY came out for the annual maintenance ... he was horrible. He was unfriendly, unprofessional.... as he was putting our AC back together, he dropped some screws. I handed them to him(he didnâ t pick them up) & he said they were NOT IMPORTANT. These are newer systems((a/c & furnace purchased thru them)). When I called the office & spoke to the OWNER, he said this was TRIVIAL. & we were wasting his time & admitted it was a new employee. HE was unfriendly & uncaring. SHOP ELSEWHERE for maintenance plan!!

Review by Patrick T. in Parkville, MD
Project: Repair a Natural Gas, Propane or Electric Fired Boiler or Radiator Heating System
I had one of their techs come out an evaluate my boiler which was showing low pressure. The tech spent about twenty minutes looking at my system and then quoted me nearly $7,000 for a new boiler and then charged me nearly $100 for coming out. I got a second opinion weeks later and it turned out the boiler just needed to be pressurized by turning a single knob. I would never call on them to evaluate a problem. It seems they are in the business of upsetting as opposed to repairing.

Project: Install or Replace a Heat Pump
We've always been very pleased with their work! We have used them for over 30 years, for multiple projects, at two different properties. They are always on schedule, they have a fair price & they clean up after the work is done!

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
