Horizon Ac And Heat

**★☆☆☆☆ – DANGEROUS, NEGLIGENT, & UNPROFESSIONAL – AVOID ON THE HORIZON HVAC** Tech **Jose Hancock** (no valid TDLR license found) left **exposed 240V wires dangling in the fan blade path** after snapping the protective shroud. A licensed electrician confirmed this created an **immediate fire/shock hazard** next to my kids’ wall. Tech never shut off the breaker, downplayed it ("would only kill a rodent"), and lied—claiming clogged coils & dead compressor when the unit cools perfectly once the broken plastic was cleared from the fan. Knew about the exposed wires and said it was fine since the unit wasn’t working and it was grounded. Provided a false license. Umber, doesn’t return phone calls, doesn’t return emails.

Someone was supposed to come out and do maintenance service on my furnace. Appointment slot 10-2 pm. Communicates through email it’s 1-5 pm. At 2:27 pm he was on the way. At 5:30 pm still no one. I called at 5:30 pm no answer. Left a message and replied to the email, is someone coming because it’s 5:30pm. I get an email from Tanya that the technician said he came. Then they can reschedule for Monday. Mind you, I have a phone, no call! I have a doorbell, no ring!. I have a dog, no bark! And I work at home! The crappiest service ever!!! If you want reliable service don’t bother with these people. And One Guard Home warranty is scheduling all the poor quality contractors to come out. I called One Guard and they wouldn’t even take their call. What a joke of a business! Don’t waste your time with these people! Period!

Like many others here, I scheduled a routine maintenance through my home warranty (Super) with On The Horizon HVAC. The appointment was originally set for May 2nd, but they rescheduled three separate times, finally arriving on May 22nd, three weeks late — and even then, three hours past the 11am–3pm window. When the technician finally showed up, the experience immediately felt unprofessional. He was not wearing any company-branded clothing, had no visible identification, and his vehicle was unmarked — no logos, decals, or any indication that he was with an HVAC company. He didn’t even introduce himself or tell me his name until he was about to go into the attic. From there, things got worse. He removed my old air filter but never installed the new ones I handed him. He made inaccurate claims about the age of my unit — saying it was from 1981 or 2006, despite the fact that my house was built well after 2006. He asked if I owned the home, why does that matter? He failed to perform any of the maintenance tasks listed in my warranty package, which included: Calibrating the thermostat Testing temperature split Checking refrigerant levels and system pressures Performing amp draws on motors and compressor Rinsing condenser coils Inspecting electrical components Testing capacitors, limit switches, and safety switches Cleaning or replacing filters Checking heat operation Cleaning and tightening electrical connections Checking contractors and condensate lines Instead, he tried to upsell me on a new system, claiming my capacitor was bad and showing me photos of "mold" from inside the unit. When I asked where exactly the photos were taken, he vaguely said "inside the unit." I later checked the attic — the photos were clearly of dust on the outside of the unit, likely from a recent roof repair. He brought no tools except a set of gauges — which he never even used — and couldn’t explain what my warranty did or didn’t cover. When I pressed him on that, he admitted he didn’t know, yet was still trying to claim that nothing would be covered. I told him to send the report to the warranty company so they could decide, and declined to start any work order. This was a complete waste of time, with no real maintenance or diagnostics performed, and zero professionalism. It felt more like a scare tactic and sales pitch than a legitimate HVAC service. I’ll be reporting this to my warranty provider and strongly advise others to avoid On The Horizon HVAC.

No call-no show! I was assigned to this company through One Guard Home Warranty. (When I researched the company, I was skeptical due to their poor reviews.) I received an email from Horizon on 11/12/25 to schedule my HVAC tune-up. I called 11/13/25 at 3:51pm and was assigned an appt. for 11/19/25 with a timeslot of 1pm-3pm. The day of the appt., Horizon was a no show. (My husband took the afternoon off work to meet with them.) I called One Guard today to have the service request assigned to another vendor. The OG rep contacted Horizon, and was told that I did not have an appt. for service on 11/19, and they claimed I had never even responded to their email to schedule service! (I have screenshots of the phone call log.) Extremely unprofessional to deny their mistake and attempt to place blame on the customer!

If I could give them a 0. I would. I have had issues with this company for years. My warranty company One Guard, has no other contractors in my area except them. They no show, call to reschedule because they are running late and a myriad of excuses. How anyone does business with them is beyond me. I have had to cancel my warranty, as it is useless to complain, they never drop them or find reputable contractors.

We used the company through our Home Warranty. The communication was horrible during the service process along with the service process itself. There was not a text/phone/email notification of when in route; only a 4 hour window.During the service day, they had to order part which took another 2 weeks of waiting. There was no communication on updates on the parts, we had to call for updates.Once the part arrived , another 4 hour window, no text of notice… the contractor ended up leaving in the middle of the job… they had to send a 2nd contractor to finish on a now 3rd day of service. Needless to say about a month later, our AC is having another issue & we ARE NOT using this company. I do not recommend them!

Avoid Horizon AC at All Costs — Unprofessional and Unreliable I rarely leave reviews, but my experience with Horizon AC, owned by Tonya, was so frustrating and disappointing that I feel obligated to warn others. We originally worked with Horizon through Landmark Home Warranty to replace two air conditioning systems. The process was a mess from the beginning. One of the outside units had to be replaced after only two years because the coils they originally installed failed prematurely. Then, the inside coils of that same unit broke just a year later, after only four years in total. That should not happen with properly installed, quality equipment. The final straw came when the inside coils failed and we were left without AC during the Texas summer. I called Horizon repeatedly—no one answered. When Tonya did finally pick up, she promised a call back by 2 PM that day. She never followed through. This happened multiple times. I even reached out to one of their workers directly, who said Tonya would contact me as soon as she had an update—still nothing. Every time I got her to answer the phone, which was rare, she would make a promise and never follow through. Weeks turned into over a month of silence while we suffered in unbearable heat. Original call end of May, today is June 30th. Because they were the original installers and tied to the warranty, I felt stuck using them. But after weeks of chasing them and zero progress, I gave up and called a third-party HVAC company (not affiliated with my warranty). They came out and replaced everything within days. What they found was shocking: • The outside unit had leaked all the Freon due to poor installation. The technician said Horizon failed to protect a valve during soldering, allowing heat to damage it and cause a slow leak. • The coils installed by Horizon were low-quality and poorly installed, which explained the multiple failures in such a short span. Basically, because they work for landmark, they do the minimum and then you’re calling them every year to replace another part or fix something. I think that is their business Model. To make matters worse, Horizon AC has no voicemail system, so you can’t even leave a message. It’s like calling into a black hole. I even told Tonya that I’d be out of town for a week and she could take her time scheduling the repair—but three weeks after that, I still hadn’t received a single call or update. It’s just pure negligence. I knew she has caller ID because she knew when I was calling, but I even had my husband call and she still wouldn’t pick up the phone. Just try see if they even answer. Bottom line: Horizon AC and Tonya are completely unresponsive, unreliable, and careless in their work. The only reason I used them in the first place was because of the home warranty company. Had I seen their low ratings beforehand, I would have stayed far away. Do yourself a favor—skip the warranty hassle and hire a reputable company that stands behind their work. Horizon AC is a nightmare And I wish I could give them zero stars and frankly sue them for the amount of work and negligence we’ve had to do because of their poor business ethics. If you want a better company call QRF mech ac…. They have 5 stars.
