"I emailed this company. He called the next day and we spoke about my concerns. He decided to come out himself instead of sending another technician. He showed up on time and got right to work. He looked at the duct and the screen and attempted to reattach it but it couldn't be done properly because there was no part to hold on to the screen. He said it was too late because the ceiling was already done. I liked that he tried to fix it and didn't charge me because it wasn't able to be fixed. He did clean the furnace. I was impressed that the owner came out himself and attempted to fix the register."

"Dan was incredibly helpful every step of the way. He broke our estimate down for us, separating the cost to just replace the boiler and to add a radiator to one of our rooms. He also had a plan to be able to do the projects separately, if we wanted. We ended up doing everything together. It was very quick, the techs were super polite and knowledgeable. Would HIGHLY recommend."

Boiler Repair FAQs, answered by experts

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

If you have multiple radiators, start by bleeding a first-floor radiator that is farthest from the boiler. Work your way toward the boiler on the first floor before moving to the next floor, where you’ll again start by bleeding the radiator farthest from the boiler. Continue this pattern for radiators on each floor until they’ve all been bled.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

Regular maintenance includes annual inspections, filter changes, and checking for leaks or pressure inconsistencies to improve efficiency and longevity.

Most HVAC service calls include diagnostic fees, which could include checking on a specific issue you’re experiencing or running through a routine inspection checklist. If you called for a particular problem, the service call will also include an estimate to fix the issue, including materials and labor. Depending on your HVAC technician and the service you requested, you might also get a general inspection of your system components to ensure everything is working as intended.
