"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."

Heating and Air Conditioning questions, answered by experts

Yes, ductless AC adds value to your home. Fixing or replacing traditional ductwork is an incredibly expensive and daunting prospect. Traditional ducts can be noisy and temperamental, with the potential for unwanted guests like hornets and rodents. Ductless mini-splits eliminate a major hassle and expense, so they can increase a home's value.

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.

You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.
