Why Is My Boiler Not Working Properly? Top Causes Revealed

Home | Why Is My Boiler Not Working Properly? Top Causes Revealed

Is your boiler working less than optimally? A faulty boiler is disruptive, and it can throw off the comfort of your home. Before a malfunctioning unit ruins your day, timely action can get your boiler up and running.

Here are some expert troubleshooting pointers from the local specialist in heating repair in Milford, NH—Sanford Temperature Control.

Check the Pressure Gauge

One of the first things you should do if your boiler isn’t working properly is to check the pressure gauge. Boilers operate most efficiently when the pressure is within the recommended range, typically between 1 and 2 bars.

If your boiler’s pressure is too low, it can prevent hot water from circulating through your system. If the gauge shows low pressure, you may need to have the system repressurized. Many boilers come with a manual that explains how to top up the water pressure, but if you’re unsure, it’s best to call professional boiler services.

Inspect the Thermostat Settings

While waiting for a heating repair company to assist you, make sure your thermostat is set correctly. Sometimes, a simple adjustment is needed to get your boiler up and running again.

If your thermostat isn’t communicating properly with your boiler, it might not signal it to turn on when it should. Try adjusting the temperature settings or replacing the thermostat’s batteries.

Look for Frozen Pipes

Your boiler’s condensate pipe can freeze from prolonged exposure to cold weather. This can affect your boiler’s performance as well as cause it to shut down abruptly.

You can prevent this from happening by listening for gurgling sounds. Additionally, be sure to check the pipe for any signs of ice blockage. To safely thaw pipes, pour warm (not boiling) water over them as needed.

A malfunctioning boiler can be more than just an inconvenience if not handled quickly. For expert boiler installation and maintenance, contact your local HVAC expert: Sanford Temperature Control. Call now to schedule a service!

I thought Derek was polite. Courteous knew what he was doing. Got my furnace fixed in one day. I was very appreciative and because of his service I will now only use you guys going forward. He’s a great technician.

I'm always impressed when a service provider takes the time to educate me about the product I bought. Eddie explained the protocols for maintaining my mini-splits
, provided me with the knowledge that he brought to the inspection and showed me how to improve the longevity of the product. In the process he convinced me to extend my service.
Good job -

Eric, our Sanford tech, did wonderful as always. maintaining our beast of a heating system takes skill. He is prompt and kind gets the maintenance taken care of quickly. He doesn’t mind the annoying dogs or the beam that you have to duck under going up and down stairs.

They check in the day before coming and Eric texts when on the way. He is always on time. We have been very happy with the work and the professionalism.

This was my first time using Sanford. Derek was amazing. He diagnosed the problem quickly, showed me the problem, and then quoted me a price which was very reasonable. He had the part on the truck and had the problem fixed within a half hour. From the person I made the appointment with, Irish, to the dispatcher I spoke with for an estimated time of arrival, to Derek, my experience was nothing but positive. I had such a great experience that I will always use Sanford for my heating, cooling, and plumbing needs. Highly recommended!

After Sanford did such an impressive job installing our new Bosch furnace last winter, it was a no brainer as to who we wanted to add a central air conditioner to our house.
They gave us two options and we chose to go with a heat pump. Jason and his team did an incredible job installing the system in just a single day. The quality of their workmanship is second to none and he couldn’t be a nicer person to work with.
Another great job by Sanford !

We had Brian B come to our home to conduct a follow up visit to evaluate our Carrier AC that was installed in February. Just like the three-man crew who did the installation, Brian B did an outstanding job of making sure that everything was working just fine. He answered all our questions and made sure we were confident that our AC would be working fine this summer. Great job.

Extremely happy with the service I received. Mike did an excellent job of servicing my HVAC system. He was very efficient, knowledgeable and took the time to answer all my questions. Also, the office personnel were very helpful and responsive to all my requests and questions regarding scheduling and pricing. I will be using them again and would highly recommend Mike.

Excellent service. Arrived on time. Asked me questions to diagnose any possible issues. Explained several things I did not know about my system.

Eric was very pleasant & thoroughly cleaned & diagnosed my system. Every Sanford employee with whom I have had dealings has been pleasant, attentive, and professional. A friend recommended Sanford to me & I recommend them to you as well. I have been very happy with my equipment & service & know I can contact them anytime with questions & concerns & they will respond in a timely manner. Thank you Eric!

Our tech was great! He was respectful of the space (and rolled with the chaos of small kiddos running around like goons), knowledgeable, and efficient. We’ve used Sanford for years and will continue to do so.

Kyle G. from Sanford was awesome and super respectful. They installed furnace and AC system. He explained everything without being condescending, helped set up the wireless system, checked it and his team cleaned up everything after the job. My standards are pretty high and Kyle not only met them, he exceeded them. Thank you.
