"THEY WERE THERE ON TIME AND TOOK A TOUR OF THE HOUSE TO CHECK LAY OUT AND COUNT THE VENTS. WE HAD MORE THEN THE DEAL ALLOWED SO THE PRICE WENT UP FROM 89.00 TO AN ADDITIONAL 230.00 DOLLARS. THEY HAD SOME EQUIPMENT ISSUES,  THEY WERE NOT REALLY SET UP TO REACH SOME OF THE VENTS IN OUR HOUSE. THEY ALSO WERE IN NEED OF A NEW BRUSH, THE ONE THEY USED WAS PRETTY WORN.
ON THE UP SIDE THEY WERE FRIENDLY AND WORKED STEADY GOING FROM ROOM TO ROOM IN ORDER TO COMPLETE THE JOB IN A TIMELY MANNER. I FELT THE PRICE WAS A BIT HIGH TO ADD FOUR MORE VENTS AND A RETURN, THE WORK WAS COMPLETED AND I HOPE THAT WE DON'T REQUIRE THIS SERVICE AFTER MOVING INTO OUR NEW HOME.

Boiler Repair FAQs, answered by experts

Over time, a radiator can leak if turned off due to the built-up air pressure, which can cause water or coolant to leak. If your radiator leaks when it’s off, turn your whole system off and bleed the radiator, then turn it back on. If it’s still leaking, you might want to have an HVAC professional look at the issue.

It can be difficult to determine the cause of a coolant leak unless you have the unit inspected by a certified professional. Most coolant leaks are caused by wear and tear on seals and joints. This typically happens five years after a unit is installed. Additionally, faulty or worn compressors, evaporator coils, and condenser coils can also cause leaks.

Regular inspections, cleaning, and checking of exhaust systems maintain safe operation, ensuring efficiency.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.
