"I’m extremely satisfied with Regional. We had three sump pumps that needed to be replaced (primary, secondary, and water powered backup). The quote was very reasonable, and they were able to do the work shortly after their initial visit. They replaced everything with Liberty pumps. Justin and Erich did the work and they were very professional. We had them quote out a couple of other items (replacing water heater, etc) and those quotes were also very reasonable. I will definitely hire them for future jobs."

"We recently replaced our Heating & Cooling system with a energy efficient furnace & air-conditioning unit. We knew what we wanted, so I received bids from 4 different suppliers, receiving bids for a apples to apples comparison. All-Temp was by far the best pricing. Our installation process went flawlessly & the installers answered any question that I had. They came back out to our home per my request on a couple more occasions, to adjust the amount of time the 2 stage system ran. Everyone that we have dealt with has been extremely professional, courteous & knowledgeable. We just received a clean & check of our system & Jen our technician met each of those attributes. I would highly recommend All-Temp for any of your heating or cooling needs. Herb Pitzman Huntley, IL"

"It seemed that thermostat & furnace were not communicating and we had no heat. I was expecting an expensive repair or possibly having to replace furnace. My technician (Johnny) arrived promptly and quickly discovered the issue...all that was needed was a cleaning."

"Cahill installed my new furnaces in a professional manner and the units work very well. The annual service is thorough and complete. I am confident that the units are well maintained and not just given a cursory service. Installation of the ducts was done quickly and professionally and their advice helped me make the right decisions. They showed up to perform the work at the agreed time and completed the work efficiently. I didn't have to allocate a block of hours during which they might show up -- as with most service companies. I'm very pleased with this company."

"I have been very satisfied with Lasco Heating & Cooling. They have been maintaining and repairing my finance and air conditioning across multiple properties for over 10 years. Keith is a great partner, giving information on how much useful life on parts to help me decide what to replace to prevent emergency service calls. Keith is very responsive and repairs things quickly."

"This business is the company that bought the older Barrington Heating and Air Conditioning. I have relied on Barrington to service my house furnace and A/C for more than 50 years. They have come to my rescue more than once. My service technicians have become friends, not just repair people."

FAQs for heat pump repair or service projects in Round Lake, IL

Heat pumps move air to cool or warm your home during different seasons. In cold weather, they extract heat from the outdoors and bring it inside to warm your home. In warm weather, they remove heat from your home to keep it cool. This efficient heat transfer increases indoor comfort, improves energy efficiency, and reduces the need for additional heating systems.

Replacing a heat pump costs between $4,200 and $7,900. The actual cost depends on the type of heat pump. Geothermal models are the most expensive to replace, with the price of the unit plus labor ranging between $6,000 and $20,000. Air source models cost between $4,500 and $8,000 to replace, while the replacement costs for a mini split unit run between $1,300 and $8,000.

The average heat pump is designed to last about 14 years, roughly the same as a central air conditioning system (12 to 15 years). Newer models can last 20 years or more. How long your heat pump lasts depends on how frequently you use it and whether you perform routine maintenance like annual tuneups.
