They are good. I was impressed with how good the service was. I like that when I go in for a simple oil change, they check other things as well and alert me if I am going to need further service in the future. Their prices are fair.

Dropped off our Mercury. Let the manager, Tony, know what needed attention (several things, a blown fuse, service with oil change, fix flat on spare tire, inspection sticker). Tony called when the SUV was ready. Pay him and picked it up.

There had been heavy rain & flooding in the city. Our sewer backed up and ruined most items in the basement. We contacted them and they installed a new water heater in a few days. We had contacted another plumbing company, but they were unable to replace the water heater for several weeks.

Heating Oil questions, answered by experts

You can expect a geothermal system to last for years. According to the Department of Energy, the underground infrastructure for the heat pumps lasts about 25 to 50 years, which includes the pipes buried in the soil. The actual heat pump itself has a life span of around 25 years.

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt.

Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.

The most obvious downside is the high upfront cost of buying and installing one of these systems. Additionally, sometimes the system can take a longer time to heat than alternatives like a boiler. Also, if something goes wrong with the geothermal pump, repairs are often significantly more expensive than repairing traditional, above-ground heat pumps.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.
