"My chest freezer broke down and I did not want to buy a new one since I could not afford the same size. I reached out to appliance parts pro and they were confident that what I ordered would fix my problem. $200 in parts later and I now have a broken freezer on my porch and am still paying the loan to this terrible company. They just want you to order parts and try them because they know you can't return them. I hate this company with every fiber of my being and will make sure that anyone that has a broken appliance will not use them.

"Frances is pleasant to talk with and was punctual and responsive. My problem was that he's probably too busy. When I received his invoice, he charged me for the recessed lights that *I* had already purchased and then I had to prove myself by showing him the receipt. He charged me 2x the Home Depot price for Romex (which I had 100 feet of in my garage, ready to go). He put in dimmer switches that didn't match the coloring of my house project (old switches were almond, new switches should have been white) and then indicated he thought I wanted almond color since those were in other places (so were the white!). He should have asked what color I wanted, but didn't and then didn't offer to replace them. This experience left a bad taste in my mouth, I'd not hire him again."

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.

DIY maintenance like filter cleaning is possible, but professional servicing ensures proper pressure, refrigerant levels, and loop performance.

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.

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

Leaks, poor airflow, reduced efficiency, and loop blockages are common problems requiring service.
