Best Heating & Air Conditioning / HVAC In Janesville

“Rock Valley replaced our boiler and on the complementary one year check-up on the system, they discovered a small leak that was dripping on the basement floor. In the end, they replaced a small section of pipe where it was leaking - at no charge, of course. Great customer service! They made it right and they're our boiler guys for life!! ?“

“Amazing! The entire process was wonderful. The assessment, the proposal, and the final furnace installation was best experience we've ever had! Highly....HIGHLY recommend J.C.!!!“

“FAST and amazing service! Just had our AC and furnace replaced and can’t recommend these guys enough! First service call was the day after we called them. New units were installed in less than a week! THANK YOU!“

“My A/C unit kept freezing up on the inside and would stop working. I called up Don Martin and scheduled a time for a technician to come service the unit. Clay was able to diagnose the issue and had it fixed in about an hour. He replaced the capacitor and topped up the refrigerant, which was about 8ozs low. He also cleaned up the unit for me and recommended I try a less restrictive filter. The total cost for the repair was very reasonable, and he provided me with a breakdown of the costs for parts and labor. The A/C is working great again, and just in time as next week temps will be in the 90’s. I will definitely use them again for any future heating/cooling issues I run into.“

“If I could give Bruce and the team at Polar 10 stars, I would. My A/C went out during the warmest week of summer. His tech came out right away and got it going again. My furnace and A/C unit were over 30 years old and I knew they would need replacement soon. The tech checked everything over and gave me a rough timeline for replacement. I opted to do it right away and Polar quoted me a great price. They did the replacement a week or so later - in and out in about 6 hours. Super polite, clean, and professional. I highly recommend Polar.“

“We had a gas line run for our dryer and A & A was the best choice. Extremely helpful and very nice! The guy who did the install was quick and paid attention to detail so it was done right. I would definitely recommend them to others!“

“That negative review was left by a competitor - completely false. Lenz Plumbing is one of the most trusted plumbers in the area, I would call them in a heartbeat. Fast, courteous, neat and tidy and priced extremely competitive, if not cheaper than the competition.“

“Agsun Corp always goes above and beyond the expectation, Workers are excellent people. I have used them several times and they will always be my first electrician(s) I go to. Thank you everyone over at Agsun for everything you continue do!“

“A tech came and fixed our AC around 10:00 last night. Highly recommend! The tech was experienced and knowledgeable. Super nice too! Thank you!!!“

“Just had them over to fix a sink and garbage disposal Awesome service Price was right“
