"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."

"We had a furnace installed by Harp on July 8th 2024 after it being diagnosed by their technician as to the reason our ac system was not functioning properly. That’s when our troubles with Harp began. The installation was not done properly, we needed 3 service calls to get the ac to work properly. The installers were sloppy. We cleaned up screws and wire and parts from the old furnace for weeks. When heating season began we noticed that the humidifier installed with the furnace was not operating. We scheduled an appointment to have it repaired and they called the day of the appointment and told us they couldn’t come that day and we had to reschedule, so reluctantly we did. They finally came and repaired it. From what the technician told me it was not wired properly. On January 21st 2025( the coldest night of the year) the furnace stopped working. We called Harp to get someone to come to repair it as we had no heat in below 0º weather I was told the best they could do is to come the next day between 2 and 6 pm. I tried to explain that this was an emergency but to no avail. I called my local oil company and they were at my door within 30 minutes( which I would’ve expected from the company who sold us the furnace) the repaired it quickly and told us that one f the wires on the control panel was not attached properly. It cost me $300. I would NOT recommend Harp to anyone. They are not reliable and do not stand behind their promises of service 24/7. Stay as far away from this company as possible. We are sorry we ever started with them."

FAQs for thermostat installation and replacement projects in Stratford, CT

Smart thermostats may be worth it for many homeowners. They come with various features, including voice control and smartphone apps. Vacation mode can help lower energy usage when you’re out of town for an extended period. Alert warnings let you know about major spikes or drops in temperature. Smartphone apps can track energy usage, and smart thermostats can learn your routine over time to adjust your temperature and reduce wasted energy consumption automatically.

You typically do not need more than one smart thermostat. While it’s common to see multiple mechanical thermostats throughout a large home, multiple smart thermostats may try to override each other. This can lead to problems with the HVAC system. Ensure the unit you buy has the option for dual- or multi-zoned systems to avoid compatibility issues.

Installing a programmable or smart thermostat may save you $180 per year in utility costs. A big part of this comes from a smart thermostat’s ability to learn and adapt to your regular routines. With smartphone apps or web-based interfaces, you also have the option to control your thermostat when you’re not home.
