Went without any major problems. Heater was attached to a water soft machine, one of the connectors broke and they bdid not have one, had to order and return to fix. This did not cause any problem, a bypass was made, and the heater was able to be used.

My wife had them put in a Master Cool swamp cooler and a heater in 2008. Like clockwork she had them service the cooler and heater each year in the spring and the fall. In 2010 I started going up with the guys and checking out the cooler when they were working on it. It seemed like it was a...

It was done as promised.I had checked out the different brands and this band has a good rating. What sold them is it was the best price for heating with air. We were replacing a propane heater and the air was basicly a bonus.

They did a great job! I was just a walk-in and I had a coupon, so they did my oil change right on the spot, and checked for other maintenance issues. I would recommend them for fast, affordable, and walk-in service.

Heating Oil questions, answered by experts

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.

Regular inspections, loop flushing, and checking heat exchangers help extend system lifespan.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.

HVAC systems usually last between 10 and 30 years, with most having a lifespan of around 20 years. Factors that impact a unit’s life expectancy include which brand you choose, how often you use it, and how well you maintain it. To make sure yours lasts as long as possible, make sure to keep it clean and schedule an annual service with an HVAC technician.

Most maintenance checks take 2-5 hours, though extensive repairs may take longer.
