"Fabulous! We needed our water conditioner serviced and other company wouldn't touch it because they didn't install it and just wanted to sell us a new one. Rebecca scheduled us for the following day! Steve Venditti was great, has 20 years of experience and knew what he was doing. He spoke with the manufacturer and they decided what needed to be done.

When you need AC heating or plumbing services, look no further than Horizon Services. For nearly 30 years, we’ve been the trusted name in plumbing heating, and air conditioning, offering an unmatched level of service at reasonable rates.

"Less than 5 years ago, I spent in excess of $10,000 to have a new unit installed with a 10 year warranty. I should have seen the red flags from the very beginning. The sales representative told us additional vents would be installed and when the installation crew showed up, that did not happen. Fast forward to the present and I am now on my 4th phone call for an appointment this season, 3 days so far of not being able to work as I waited for a technician to come diagnose the problem. The 3rd. tech came last night and indicated that the work the other tech did was not for the root of the problem. (I was told in front of witnesses that the work needed to be done, was not covered under warranty, would cost me $367 and would fix my issues)In fact, the 3rd tech only made the issue worse by leaving our attic return unscrewed and overfilling our unit with Freon that the 4th tech had to remove from our system. Upon leaving last night I was told that everything was corrected. Today - my home is slowly creeping up in temperature (presently 80 degrees inside, while set to 72). The company keeps trying to sell me a "maintenance plan" and I keep reiterating to EVERY one who pushes it that we have been getting tune ups/cleanings elsewhere and will only use them for warranty issues since we have had NOTHING but problems with them."

From sinks, toilets and tubs to main lines and sewers, our team of drain & sewer professionals are ready to provide you with fast, expert services.

"They truly live by the code of "you get what you paid for". The price was cheaper than expected (and they included a free estimate too). So ultimately, our slow bathtub drain was cleared. However, the technician had terrible housekeeping. After stripping the caulking around the overflow valve, they left the caulking pieces in the bathtub and told us to flush them down the drain (?!). They said the provided bio solution would clear the pieces just fine...but why do that when a trash can is less than a foot away?? Then, they did not offer to reseal the valve they just opened...just left a mess for us to pick up. As such, we will not be using them again next time...free estimate or not. If we wanted the bare minimum, we would have done it ourselves."

Tankless water heater installations FAQs

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
