"Great, they were friendly and professional. I also had a crack in my windshield that needed to be replaced, they advised me of a person they use and the cost. No pressure to go with their provider. I chose to go with another glass company and I just had to return to get my inspection stickers put onto my new windshield.

"Inspection went well. HVAC equipment was installed and maintained by Horizon. Technician was on time, and was professional in interaction with me. He clearly explained what he was going to do, and explained the results when the inspection was completed. there were no unexpected charges. Not the cheapest, but I am looking for good, not cheap."

"I have nothing but praises to sing for this company! Our heat stopped working on us last week right before the temp was expected to drop significantly. I checked Angie's List, found Air Temp Solutions, submitted my issue and within minutes I received a phone call to set my appointment. They sent over Rob Teixeira who was EXCELLENT!!!! He immediately detected the issue which was the flame sensor, fixed it and viola...we had heat again in no time! We are planning on doing further work with this company as we need to have an additional return grille installed. If you need fast and reliable heating or AC this company (and Rob) is who you should go with...you will not be disappointed!!!"

"They are very good and the mechanic is good. I paid a deductible and I had an extended warranty; the repairs were somewhere around $1,300. They are very knowledgeable and seemingly very honest. If something is not right after they have done it, they make it right. They give me a ride home if they have to keep the car. They are very well qualified and keep up on all the latest technologies."

Install Boiler questions, answered by experts

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.

If you're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.
