"I would steer clear. 1. Pay with check discount is not guaranteed. We had a service done in mid-February, and were mistakenly charged the full amount, even though we were told we would receive a 3% discount. We were then told they would mail a check. No luck. 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."

Heating Oil questions, answered by experts

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

If a geothermal heat pump is installed correctly, then you shouldn’t have to worry about having a backup heat source such as a furnace or oil boiler. However, there are geothermal systems installed that include a backup in case the heat pump fails due to extreme cold. This is simply a backup heat pump you’ll likely never need and not an alternative heat source.

You can expect a geothermal system to last for years. According to the Department of Energy, the underground infrastructure for the heat pumps lasts about 25 to 50 years, which includes the pipes buried in the soil. The actual heat pump itself has a life span of around 25 years.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.
