"I would steer clear. 1. Pay with check discount is not guaranteed.

Debbie has my Zelle QR code and info and still refuses to refund the overcharge. She would rather argue than honor her discount. 2. Does not stand behind their "100% Money-Back Satisfaction Guarantee on Service." We had an error code on our furnace. Tech came out and diagnosed as a bad inducer. We believed him and purchased a new one. They installed it right away and also did an inspection. Total was about $1100. Steep, but not bad since the tech said that should get us a few more years on an 18 y.o. furnace. The inspection went well and we were happy. Next day the error code was back. Different tech came out and diagnosed as a control board issues. $900 to fix. Ouch. He was at the house for a long time to do the diag. After asking for detailed information, Debbie refused to give any insights and lied to us about not being charged any mark up on the inducer. At this point I was definitely not satisfied! The more questions I asked to get to the truth, the more Debbie blamed us for the age of our furnace. I asked for a refund of the service and told her she could come get the part once we received the refund. This was because we STILL had not gotten the check discount she promised us! The part was charged at $600+ so the remaining amount for the service is $475 which includes the inspection that failed to find the control board issue. That and the check discount comes to $500. on a nearly $1100 bill. But Debbie would rather blame us for asking questions and not being grateful for the time they spent NOT FIXING THE ISSUE! Debbie lied to me when she said she would give the refund and come get the inducer. She has gone back on her word and refuses to make it right according to her own posted "promise." Debbie can send the refund amount through Zelle or bring a check when she picks up the inducer to resolve this issue. The BBB has now directed me to the IL Attorney General."

Generator Install questions, answered by experts

No, you shouldn’t use an extension cord to plug a generator directly into your home without using a transfer switch. That’s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of electrical fire or electrical shock to you or any workers repairing lines on your local electrical grid.

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home

In many cases, you’ll need a permit or basic inspection to install one of these large generators. Since they include significant alterations to your home electrical system and many produce exhaust fumes, local governments often require jumping through a few hoops for general safety purposes. Your installer may be able to help you with these permits.
