"Initially there were a few issues that came up, but Don Hughes did a great job with what he was given on the fly. He really does GOOD, CLEAN work. Don kept me informed through EVERY step of the process because there were the early "snags" that really slowed his installation process. Don has been trained on Navien Tankless Water Heaters, so when my application required another (NEW) Rinnai system (because of space considerations), Don was able to quickly adapt to the situation and install PERFECTLY a product he was never trained on, serviced or installed before. The entire ECO staff was fantastic to work with from the beginning estimate to the end when they had another teammate call and follow-up on the whole project. Don did a great job cleaning up before he left, couldn't tell he was even there. I will be staying with ECO Plumbing, Electric and HVAC for my home appliance servicing and upgrades. Thanks ECO!"

Heating Oil questions, answered by experts

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

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.

Service costs range from $200 to $1,500, depending on maintenance needs, system age, and labor.

Costs depend on system age, type, labor, and whether part replacements are necessary.

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives). 

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.
