Electric Furnace or Forced Air Heating System Repair Service
$14,000
Our oil furnace/HVAC could not be repaired. We purchased a new unit, the install went well thanks to two professional technicians from Delaware. Our issues began after a visit from an inspector arrived 6 days later. He wouldn't listen to any question and replied "If I answer that, I have to charge you!" We have no idea what he did to the new thermostat, new oil furnace, and/or to the AC condenser. We reported it within 6 days when the outside temperature was in the 80's. Today a technician was scheduled between 8am-12noon. I was told he would be a little late...Another call advised that he needed to be replaced with a technician that is knowledgeable about "Oil furnace/ HVAC systems"??? We are now at the mercy of a longer wait time and hope someone will show up today with the temperature rising in our home. Praying that all will be corrected at no additional cost to us.

Dear consumers, I would not recommend horizon services these specific reasons. I believe I was misleading on the pricing, I was told my bill would be no more than 500.00 dollars if was to supply the faucet, this was very confusing when I received my credit card statement there was an additional 217.00 dollars reacted on that. SO MISEADING I WOULD NOT RECOMMEND THIS COMPANY I WII BE PASSING THIS IN MESSAGE ON TO FRIENDS AND NEIGHBORS. THIS PRACTICE IS A GOOD WAY TO LOOSE CUSTOMERS.
