"I hired Bill to change a 15amp outlet to a 20amp. The job was more in depth than I anticipated because of the distance from circuit breaker to outlet location and the need for new wiring. We discussed discussed other location possibilities, but Bill was confident he could complete the job as I had planned. He did so with absolute confidence and professionalism. Much appreciated!"

"Total Ripoff! My boiler stopped working the other day and my usual company was unable to come out due to being short-staffed that day. I resorted to google and unfortunately came across Aire Serv. Their technician (who was very nice) came out to assess the situation and determined it was caused by a damaged pilot assembly. After calling around for replacement parts, I was told that the parts were out of stock until later in the week. Despite this, I was still charged $234 for the trip fee and diagnostic fee. I was then quoted $1112 for the repairs to be done once the parts were in. I shared this quote with my normal company and they were appalled! Thankfully they fixed the issue for less than half the price Aire Serv was going to charge me! PLEASE do not use this money-grubbing company, and instead use a local independent company if you need heating work done!"

Heating Oil questions, answered by experts

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.

A geothermal heat pump system will take about 10 years to pay for itself, and it has a life span of anywhere from about 25 to 50 years. Installing a geothermal heat pump will cost about $14,250 upfront, but it can reduce your energy bills by around 65% when compared to a conventional HVAC system.

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

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.

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.
