Review by Andrew M. in Owings Mills, MD
I have lived in this house for 26 years and this is BY FAR the WORST experience I have had with a repair contractor. I would tell people to never call or recommend this company to anyone! I called them on a Saturday because they offer same day service and I had no heat and yes they did come out the same day (which is certainly something)... the young man took one look at my problem and immediately recommended a new system. He told me my system (only 8 years old) was shot and that I could begin replacing parts but that would run me $4000.00. When I asked him why I would not just replace the system at that point, he immediately called his salesperson and made an appointment for me to meet with her the very next day. At that point, my *radar* should have gone off, but it did not. Horizon provided me with a ridiculous estimate to replace the system for $10,000.00 which I knew was way high. I ended up with a mid-priced Rheem system for $6000.00 installed by another contractor. But it does not end there, not even close! A month after the install, I started having the same problem I had started with: faulty thermostat wiring. The contractor who ultimately fixed the problem indicated that this was my problem all along and I very likely did not need a new system at all. I was the victim of an overly-aggressive Horizon employee who was merely out to sell me a new system at any and all cost. Do not use this company! They only want to sell you new equipment! When I called Horizon Services to voice my displeasure with the result of my experience, they offered me the cost of the service call :$99.00 and nothing more! They said they stand by their original estimate! Which was wrong!!! And that original estimate ended up costing me $6000.00 that I did not need to spend!

Review by in Ellicott City, MD
Project: Repair Natural Gas or Propane Furnace / Forced Air Heating System
When they come to install my unit, the rep brought in so much dirt, I had to clean my carpet. Overall the work was good. Shop around before picking a company. They have sales rep waiting to sell you what you don't need.

I didn’t spend any money. After visit they didn’t find what is wrong with my hvac. It continues to make the loudest noise when it stops heating.

Very impressed with Clifford, he was very responsive to all my concerns and even came over to install the unit on his day off because I requested him personally. He continues to answer any questions I have had after the installation.

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.
