5.0 Ed N. Middletown, DE

They were fast, Skilled, neat and very polite and respectful. Heaters have been used for a couple of years now with no issues.

5.0 Frank V. Wilmington, DE

Every single person we dealt with from the Customer Service people, the technician, CJ, the estimator, Kevin and the installation crew could not have been nicer and more professional. Not a happy time when you have to replace your heater, but they all made it an outstanding experience. Iâ d highly recommend One Hour to anyone needing HVAC help.

1.0 Paul M. Newark, DE

Lack integrity and ownership of their work! Said I needed a new compressor and air handler when what I truly needed was new ductwork. They also tried a bait and switch of the air handler by installing one with a lower seer than the one we agreed on. The system finally started working the way it should after several attempts at patching the ductwork. The end result was installing industrial size ductwork that eliminates access to most of my attic.

5.0 Mary R. Smyrna, DE

Iâ ve been using One Hour Heating and Air Conditioning for several years now and have always been happy with their service. Iâ ve never felt like I was being ripped off or pressured, which is so important. They come when they say they will and everyone Iâ ve worked with has been friendly and professional. They even wear booties inside to protect your floors. Everything is expensive now, but I feel like their prices are fair and they really try to fix your system instead of jumping to selling you a new one. One of the few companies I would actually recommend to a friend or neighbor.

5.0 Manuel V. Bear, DE

Paul was very professional and knowledgeable, he did an awesome job and got my air conditioner working in no time!

4.0 Gladwyn D. Bear, DE

4.0 James V. Middletown, DE


5.0 Ronald J. Newark, DE

Very professional

5.0 Tyron C. Bear, DE

Hai L was a good technician, he identified the problem and went to work on it. He was concerned bout me not having heat, so he went to get the part himself otherwise I would have to wait for them to order. One hour heating and air conditioning will be my go to for all my heating and air conditioning needs.

5.0 Rob M. Middletown, DE

Very prompt, customer service conscious, very professional. Great job!

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.
