"Everyone that we dealt with couldn?t have been nicer. We had a tub to shower conversion which was completed in one day. Matt, the installer, laid a tarp down from the door to our bathroom to protect the floors. He asked for our input when he was installing the shelves and grab bars. After he finished cleaning everything up he explained how to used the new shower head and what to use to clean the surface. The next day we texted him with a question and he immediately answered. We couldn?t be happier with the job done and the professionalism of the company."

"Technician Jim was not impressive. Was not confident when answering the questions I asked. Very contradicting.. Tried to sell product for items that were not even in need of repair. Spoke negatively about the company and made excuses as to why he could not perform his job due to lack of information from dispatch or technician manager. Said he would follow up, I never heard from him. Blessing to me, I decided to go with another HVAC company. I typically would not put names out there, but please be careful if you get this gentleman as a technician."

Boiler Repair questions, answered by experts

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

Most HVAC systems last between 10 and 20 years, with an average life span of 20 years. The individual components within an HVAC system have their own life expectancies as well. For instance, a furnace often lasts for 15 to 30 years, while a heat pump might need replacing after 10 to 15 years.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

With proper maintenance, boilers last for around 15 years on average. A cast iron boiler may last longer, over 20 years, but you should always consider the efficiency of older boilers and opt to replace an old one if it’s significantly lower than newer, high-efficiency boilers. Otherwise, you’ll be spending more on your utility bills each month.

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.
