"My loft above my garage was humid and a bit uncomfortable from what I was expecting. I’ve watched enough home repair shows and understand air flow enough to know it would never be perfect, but something was off because of the humidity issues. Mike came in and did an inspection, confirming that there was a lot of room for improvement in the garage ceiling. The heat camera was showing that there was a lot of heat transfer happening in the loft, foot prints (from boots) leaving heat transfer marks which is unusual and recommended dense insulation pack to fill the void. I sat on it for a few weeks, called and scheduled for the 17th, but got in early due to an opening. It took several hours to complete the work, and the folks said it had 5” bat insulation but a 17” void, which confirmed Mike’s original thought that there was a gap between the insulation and the loft floor which was carrying the heat from the outside into the floor."

Since 2005, RCM Heating & Cooling has been providing New Lennox and Mokena with excellent workmanship, outstanding customer service, and quality products. As a full-service company, their highly trained and experienced technicians can assist you with anything from installations to maintenance to repairs. In fact, the technicians are proud experts when it comes to troubleshooting and diagnosing issues. When you need a heating or cooling problem solved, they are the ones to turn to. They are also indoor air specialists and can help you determine which product would best improve your home’s overall comfort. For same-day service, give them a call today.

"Heating season started and my forced air furnace failed. Of course all the HVAC repair companies were backlogged. RCM was available, came within hours, and the problem quickly diagnosed by the repairman (Jeff). The problem? My total bill was $675.00 for two 1 hour visits to replace an inducer motor. The OEM replacement part is $125 on-line. So, $550.00 for two hours of labor? I asked about the apparent high cost and was told was the cost of the part was responsible. When I pointed out the part was available on-line at $125, I was told that RCM has to pay more for a replacement inducer motor than I would. Having worked in the trades in my youth, I've never heard of a contractor paying more than the public. I don't know whether RCM's prices are fair, average or I got shafted, but I do know when I'm being fed a line. My advice is to get your furnace checked well before the season starts."

Energy Efficiency Auditing questions, answered by experts

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.

Insulation is measured by R-value, which is the measure of a material's ability to resist heat transfer. The higher the number, the better the insulation. When installing insulation yourself, you need to determine the optimal R-value you need to keep your home warm in the wintertime, cool in the heat of summer, and energy-efficient all year long. Each inch of insulation provides between a 3 and an 8 R-value. The climate where you live plays a major role in what R-value you need and the price tag you might see in your insulation installation.

The best way to save money on home heating oil is to get large deliveries in the summer months when the prices are lowest. However, this method will only work if you have a separate storage tank or an unusually large primary tank. You can sometimes save money by opting into a delivery contract, as some companies offer set prices that they believe will sit at the average cost over the contract term. If the price of oil rises, you could enjoy some savings, but keep in mind that you might also pay a bit more if the price decreases.

Yes, most audits include a report with prioritized recommendations for improving energy efficiency. Confirm with your auditor.
