They then gave me a quote on two water heater options. I chose a new 50 gallon Rheem gas water heater and it was completely installed within a few hours. I couldn't believe how quickly my problem was resolved! The young man that installed the new water heater was very professional and careful about making sure not to have any leaking on our newer carpeting when he removed the old tank. He also explained to me the basics of the new water heater.

"Needed to hook up my portable generator to the house. Mr Sparky was the first to call from angi so I asked for a quote. They came over very quickly and gave my wife and I a very good quote we thought. We didn't even get another, Slept on it, they called back the next day and we set set up a date. Mario showed up (very nice guy) . Said it would be a couple hours, and it was. They didn't need to turn off the whole house which was good and wired in a new electrical panel and plug on the outside. We tested it, and it worked perfectly. We are very happy.
Thanks guys....!"

Heating Oil questions, answered by experts
It’s a better use of energy (and your money) NOT to run an ERV system all the time. Most experts recommend that you cycle your ERV system on and off throughout the year. However, the recommended advice could change based on your climate, the number of people in your home, the size and style of your home, and your heating and cooling system. Contact a local pro for more specific advice.
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.
Yes, including optimizing settings and suggesting upgrades if needed.
Costs depend on system age, type, labor, and whether part replacements are necessary.
Leaks, poor airflow, reduced efficiency, and loop blockages are common problems requiring service.
