A little research on the web was leading me to think I was going to have to replace the water heater. However Wallace Plumbing came out and inspected the system and quickly determined that all that was needed was to clean out the short In/Out pipes on the top of the water heater. About an hour...

They have done oil changes for me and also exchanged power steering fluid for me. My experience has been good and they have always treated my wife well. The only complaint I have is they change management frequently but they do good work.

They are good for checkups including oil changes. They are equal and fair. Their prices are normal and not over extravagant for a car dealership. They are perfect on responsiveness. I would use them again.

Heating Oil questions, answered by experts

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

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.

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.

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

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