How can we help?

More than our logo is going green!

Reliable Heating & Cooling offers many “green” products that are not only good for our environment, these products will help keep more “green” in your pockets. In today’s economic climate, investing in energy efficient products for your home is a smart choice. Reliable offers many Energy Star certified systems that often qualify for additional rebates and incentives from third parties. The federal government has been offering tax credits for the purchase of certain high efficiency equipment.

Check out the many earth friendly ways Reliable Heating & Cooling can help you reduce the amount of energy your home consumes.

  • The new R410A air conditioners are not only ozone friendly, these units often use 1/2 or 1/3 of the energy used by your existing air conditioner.
  • “Duel-Fuel” or “hybrid” systems offer flexibility by combining a high efficiency gas furnace with an electric heat pump. These systems use smart technology that can be adjusted to use the most efficient form of energy.
  • A tankless water heater only operates when you are using hot water. Replacing your old tank water heater will lower your gas consumption, AND, with a tankless water heater you don’t run out of hot water!
  • The simple installation of a programmable thermostat can lower your energy consumption using your existing equipment.
  • Installing a whole-house humidifier allows your home to feel warmer at lower thermostat settings.

We can help you lower your energy consumption in many other ways, and an energy analysis of your home from Reliable Heating & Cooling is absolutely FREE.

What our customers are saying

Had a small gas leak for a property I was helping a friend sell and we found out late last night. We reached out to Reliable H&C and Derrick was over first thing in the morning. He was friendly, professional and knowledgeable. He answered my questions with a smile. Derrick was a rock star. Will absolutely call him again. Bravo

Connor Kapp

We had a emergency water leak problem with our AC unit in the basement of our recently purchased condo. Called Reliable and Derrick was there within a couple of hours. He was polite, knowledgeable, and friendly. Derrick quickly found the problem and repaired it. He also checked the system overall, pointed our some concerns and answered all my questions. I can’t say enough about how satisfied we were with Derrick and Reliable Heating & Cooling! We would definitely recommend them!!! Thanks again!!!!

Terry Mills

I had a system malfunction on Sunday evening December 12, 2022 on my Carrier Infinity ICS purchased in 2008.I am a first time caller to Reliable. Marty called me back and had his Tech dispatched at 8 AM the next day. The unit had failed and was dangerous to use. He had a new system by the next morning. They installed it and I was completely satisfied with their service and response time. I overwhelmingly recommend Reliable and will be using them from now on.

DM

Reliable has installed and maintained our last 2 furnaces and AC. Our experience with them has been great. Just yesterday we had an issue with our AC. I talked to Marty and he said he’d have someone out the next day. They even were able to accommodate us with an afternoon call. Derrick arrived promptly on time and had us up and going again in 15 minutes (bad capacitor on the condenser unit fan motor). With the prediction of high 90 temps, we were so thankful to have AC working again.

Keith Scherer

Have been with them for more than 10 years. They provide exceptional service…from the time they call to remind you about setting an appointment to the actual service day. Derek (and all their other technicians) are knowledgeable, professional, prompt, and open to listening to questions and pay attention to details. Never had a problem with anything. Thank you for a job well done. Good pricing.

Seema Chouhan

We have used Reliable Heating and cooling for all of our heating and cooling needs. We needed some water heater work and Ralph came out and took care of it right away. Ralph was very professional and knowledgeable. He got the job done very quickly and everything is working great! I always recommend Reliable to family and friends. They truly are Reliable!
