"Issue with Bell Mechanical This past August of 2024 we had a heat pump system installed in the house by Bell Mechanical. Unfortunately, we have had nothing but issues since with the biggest being no heat multiple times and now again today we are without heat in the majority of our house. It is freezing outside, we have a toddler and within the past week this is the 2nd time we have no heat (4th time since the system was put in). Not only is this a life safety issue, but it also is heart breaking to have your toddler tell you they are freezing. Looking for advice on next steps. We have never sued anyone or threatened to sue but this may be the time as we have had nothing but issues since the beginning. From the start we made it very clear that everything needed to be done to code and permitted. We were doing a lot of major renovations at our house and everything was being done to code and permitted. John (the salesman) at Bell said that was not a problem. John also told us that the only additional cost we could potentially incur outside of what he quoted us for the system and its installation would be a $500 fee for the installation of the heat strip. We accepted this and moved forward. After Bell removed our central air system and installed the new carrier system we got his with additional work needed at the tune of over 2k. Needless to say we were not happy. John told us the electrician they use and that if we used that electrician there would be no delay but if we used ours that it would cause a delay. So, we went with what John said as he was the expert. John got the electrician to come down a little in price which we were grateful for. Fast forward to when the building inspector came out to close out the permits for the work Bell did and other work being done at the house, the inspector told my contractor that the heat pump was not done to code. We were told that the electrical for it was not done to code and he could not close out the permit. My husband talked to the electrician Bell gave us who informed us that Bell told him to “cut corners” which was part of getting the cost down slightly. Reminder, we NEVER said to do this, we made it clear that everything needed to be permitted and even paid the permit fees to Bell. Back and forth with Bell and the electrician got the electrician to fix his work at no additional cost but Bell still needed to fix the outside plug which was not to code. Giovanni at Bell agreed that Bell would fix this issue at no additional cost. It has been 3 months now and Bell has still not rectified this issue and Giovanni and John are both nonresponsive to our follow-ups. Bell has also had to come out 4 additional times because our system was not working and again today, we have no heat. Today will be the 5th time they have to come out for issues on a system that is 4 months old. This is not OK. We have given Bell ample time to rectify the issues. Clearly they did not do the install properly and there is also the possibility we have a faulty system. We have never sued someone or went to court but then again, we have never had such large and costly issues."

Thermostat installations and replacements FAQs

It's often worth replacing your old thermostat with a newer model that can enhance your home's comfort and energy efficiency. Upgrading to a programmable or smart thermostat can save you up to $200 per year on energy bills. Plus, smart thermostats offer convenient features like remote control and learning capabilities, making your home more comfortable and easier to manage.

Signs of a bad thermostat include your HVAC system not turning on when it's supposed to or failing to reach the desired temperature. If the thermostat's display is blank or not functioning properly, it could be malfunctioning. Another indicator is the HVAC system running continuously without shutting off or cycling on and off too frequently. You might also notice uneven temperatures throughout your home, with some rooms being too warm or too cold. These issues suggest that the thermostat is failing and may need repair or replacement to ensure your HVAC system operates efficiently.

A thermostat should last between 10 to 20 years, depending on its quality and how well it's maintained. Over time, dust, wiring issues, and general wear can affect its performance. Even if a thermostat is still functioning after 10 years, you might choose to replace it to take advantage of newer energy-saving technologies and smart home integrations. Upgrading to a modern thermostat can improve efficiency, offer more control over your home's climate, and potentially lower energy bills.

The number of thermostats you need depends on your home's size, layout, and heating and cooling zones. In a standard single-zone HVAC system, one thermostat controls the temperature for the entire home. However, larger homes or those with multiple floors might benefit from multiple thermostats linked to a multi-zone HVAC system. This setup can offer better comfort and energy efficiency: It lets you customize the temperature in different areas, so you're only heating or cooling the spaces you're using.

Replacing a thermostat typically takes a professional technician about one to two hours to complete. If you're swapping out an existing thermostat for a similar model with compatible wiring, the process can be done in less than an hour. However, installing a new thermostat that requires additional wiring, such as a smart thermostat, or moving the thermostat to a new location can extend the time to two hours or more. Complex installations may also involve cutting into drywall or integrating with other home systems, which can add to the duration.

There are a few things that can cause your home thermostat to fail. The most simple one is age and cleanliness. Dirt, grease, dust, and other small particles can clog sensors and cause malfunctions in readings. You may also have a failing power supply and loose connections, and the simplest cause is that it isn't installed in the right place in your home so it can't properly sense air temperature. Repairing a thermostat costs around $210.
