"Kurt was absolutely excellent. He quoted me a fair, comprehensives price after coming to my house and explaining the issues and what needed to be fixed (I found out my main shut-off was leaking and not up to modern codes!). Then, once I gave a deposit, I had the job scheduled and completed within a week. After the job was completed, he gave me a run-through of everything that they did along with a short tutorial on the water softener. That included fixing the main-shut off as shown in the picture. Finally, after signing one form, he said that he would turn in the $750 rebate to ALASD for the water softener for me. Overall, I would certainly use them again for any of my plumbing issues."

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.

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.

Yes, many providers offer organic or eco-friendly treatments. Confirm availability with your contractor.

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.
