Customer Testimonials

Have been using Horizon for the past few years for maintenance and repair of our HVAC, and recently had them clean our vents. We have been happy with their service and their professionalism. Have not had problems with their work, and if there was ever an issue after a visit, they came back out and addressed promptly. They will usually point out things that they note that could become potential problems, but it is never a high-pressure sell.


HIRE THIS COMPANY!!! We just had our furnace and AC replaced and they did MORE than they promised. Before Horizon our 2nd floor was 8-10 degrees warmer in the summer and now after the installation the upstairs and mainfloor are exactly the same!!! They are professional from setting up and doing the estimate, installation, inspection and follow-up! I requested service a few days after the install and they came out that day! I would recommend them to everyone!
Thank you Horizon


By far the most professional and knowledgeable company I have ever worked with! We worked with 4 different people from Horizon Mechanical and all of them where top notch. They are not the cheapest, but they are not the most expensive either. You really do get what you pay for. Extremely dependable and trust worthy. You can tell they are the kind of people who genuinely want to do the right thing. They now have a customer for life!


Absolutely first class company, people and service! They go above and beyond to educate and inform. Their level of communication is a 12 on a scale of 1-10! The communication, care and competency were exhibited throughout the event - from Carolyn coming by to estimate the job and make recommendations - to receiving an email with a photo of my technician and the truck he would be driving - to the level of professionalism in the tech who arrived - his communication and explanation of the job - and the time - and his care for my home - all exceeded my expectations! Horizon is my GO TO company! Thank you to all the professionals throughout the organization!


The technician arrived on time and even called me 30 minutes before the arrival time to let me know he was on his way. He did a thorough job cleaning and checking out the furnace. After the furnace maintenance was complete he helped me pull out my stove to check the gas connection for leaks. Above and beyond! Thank you!


Horizon Mechanical is a solid company all the way around. Each member of the staff is dedicated to making sure you are a satisfied customer. We are service contract members and it really takes a load off your mind to have them just a phone call away for heating, cooling & plumbing service.

Highly recommend.


Great Company. Very thorough and methodical when working on heating and sir conditioning system.

From Our Website

We'll do business with Horizon again, they take care of our concerns, show up on time, go above and beyond, do the work they say they are going to do, and are professional at all times. We cannot stress enough how important it is for a homeowner to have annual maintenance performed on their homes heating system, whether it's a gas furnace, hot water boiler, or a hybrid of the two, nothing is more effective at helping to eliminate unexpected failures in their homes comfort system, resulting in a no heat situation.


Because we spend so much time in our homes (up to 90 percent of our time) and the tremendous improvements in energy efficiencies in our homes, high efficiency heating and air conditioning equipment, better windows and insulation, air sealing and weather stripping. That's all well and good for the lower energy bills, but because of the tighter air envelope, it allows for the trapped pet dander, dust, pollens and other allergens to recirculate in your home, which can create asthmatic and allergic reactions.


When is it recommended a homeowner begin to investigate replacement of a furnace? When your furnace is still operating! You are in a better position to weigh your options and make a focused, informed decision when you are not in an emergency situation. If you wait too long you risk a heating failure, which always comes at the worst possible time. Holidays, weekends, extremely cold temperatures, a home full of guests, that always seems to be the time an older furnace will give out. Homeowners then find themselves in the uncomfortable position of hiring a company to install a furnace, just because that company could get to your home quickly.


Our technicians are skilled in the repair and servicing of all brands of heating equipment for your office or business. Handling No Heat or No Cooling situations on rooftop mounted equipment, or RTU's as we call them in the industry. Handling thermostat, control and other occupant comfort issues is no problem either. Some minor issues like dirty air filters are common problems, but in some cases there are more serious issues involved, and we can handle it all. Please let us know when calling if we will require any unusual equipment access information, such as needing to contact building management for a key to a certain room, this will allow us to serve your needs quicker and faster, and help eliminate some confusion.


Our technicians are background checked, uniformed and NATE certified professionals trained to properly diagnose, repair and service all types of Air Conditioning Systems as well as handle and dispose of refrigerant and freon per EPA requirements. Servicing an air conditioner could easily be passed off as, "If it's not broken, don't fix it", resulting in a neglected home appliance, and not until a failure occurs do homeowners give this appliance any thought. Not changing the oil in the family car, would be similar to not servicing your homes air conditioner.


Our technicians can provide a Whole House Plumbing Inspection at no additional charge during a service to identify any other potential issues with your homes plumbing fixtures, before it becomes an emergency; waste and water lines as well as install valve tags to help you quickly identify emergency safety shutoffs such as gas and water valves, in case you ever need them. When a water heater needs to be repaired sometimes you know about it right away, think cold shower, or a leak has developed and you may not catch it right away, but eventually you find water on the floor around the heater.


Horizon Services Plumbing, Heating and Air Conditioning has extensive knowledge of in-home safety equipment to help you keep your loved ones safe. All of these above listed measures as well as others are either addressed, inspected or can be discussed with you during a Peak Advantage Service Agreement visit.


One of the first things to consider when it comes to handling indoor air quality issues at your office or business is the selection of the proper air filter for the type of environment that the equipment provides conditioned air to. The degree to which the filter removes particulates from the air is directly proportional to the length of time between maintenance or replacement interval that the filters in the equipment will require. It is also important that the filters fit properly in the equipment, to ensure that the heat exchanger surfaces, such as coils, stay clean for as long as possible, thereby maintaining efficiencies to keep operational costs as low as possible.
