"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

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.

In general, it’s a good idea to bleed air from your heaters at the start of every cold season, before you move your boiler system back into active mode. Early fall is a common time for this task. However, some heating systems don’t need much manual bleeding because of automatic bleed vents and other components.

The average cost for HVAC repairs is approximately $350. However, prices can range from as low as $100 to as high as $3,000 or more, depending on the type of repair and the extent of the damage. For example, a relatively inexpensive capacitor replacement may cost $100 to $500, while a major compressor repair can range from $750 to $2,000. Other common repairs and their typical costs include:

  • Blower motor repair: $200–$500

  • Circuit board repairs: $100–$600

  • Evaporator or condenser coil repair: $400–$1,500

  • Heat exchanger repair: $100–$200

  • Thermostat repair: $175

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

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.
