"We got several quotes from local HVAC providers / installers. We felt the most comfortable with the salesman from Extreme One Hour Heating and Air Conditioning and I got the best price from them which also included a 2-year membership in their Comfort Club (Spring and Fall service visits to check and tune-up my system). We were an all electric home until a couple of years ago when we added natural gas. When our 16-year old Trane heat pump developed problems this proved an ideal time to switch over to a gas furnace and air conditioner. We stayed with Trane as we were happy with our Trane heat pump. Because we have some space constraints and limitations for our new system, Extreme sent out their system designer the day before the installation to develop a creative solution that met our requirements and efficiently maximized the space with which they had to work with minimum impacts to us. The day of the install they arrived on time, were friendly but very professional and treated our home as if it was their own. They also took the time to answer my questions while the worked. Since it was bitter cold that day, they needed to be in and out all day, and we were without a heating system most of the day, they brought a heavy duty space heater to keep us from freezing until they were done. At completion, showed us how to use the new system including the new programmable thermostat, changing filters, etc. and they cleaned up everything and left our home better than they found it. They then submitted all of our rebate paperwork to Vectren and DP&L for us. We were very impressed with the whole process of buying and installing a complete new HVAC system. I highly recommend Extreme One Hour Heating and Air Conditioning for and HVAC installation work!"

"They could not use the furnace that was advertised, they had to upgrade. Something about a down flow and up flow. The one being offered was either down flow or up flow, I cant remember, and I needed the other one so they had to upgrade it. I spend several hundred dollars more then that. I thought that they were prompt, the guy that came in explained everything in detail to me, showed me how to install the filter. He created it so I could easily install the filter which I couldn't on the other one. He was patient, took his time, and what was required to do a professional job. He was very professional, cleaned up after himself and was good."

Hi! I am a chemical engineer specializing in industrial utilities by trade who enjoys fixing and building things in my free time. I offer services such as furniture building, home appliance repairs (ovens, refrigerators, freezers, dishwasher, garbage disposal, washer/dryer, water heater, A/C, furnace, sump pump, etc) small scale plumbing or drainage projects/repairs (exterior storm water drainage, pvc/copper piping- I do not do cast iron, faucets, etc). I can install new appliances, but might need help lifting and setting the appliance (I do not dispose of old appliances). I also can repair kitchen stand mixers such as Kitchen aids (rebuild/regrease).

"I was very pleased as my problems were quickly diagnosed and quickly fixed.  And while I chose to get a new air conditioner, I'm the one who brought up the idea -- it wasn't the result of a pressured sale -- and when the technicians checked out my also-aging furnace, they confirmed that the heat exchanger was in good condition.  A lot of places will tend to find cracks on older heat exchangers quite easily.  The A/C install went smoothly and the price was exactly what was quoted.  Will seek out Wells again.

"We hired them for an initial inspection of HVAC systems when we saw some problems on a home inspectors report. Etta who works at the front desk was wonderful to talk with about the different issues and setting up appointments. After the inspection, we learned that most systems were fine, just the AC needed fixed (it was 15 years old). Lloyd was very helpful explaing the difference between repairing and replacing the unit, which helped us make the best decision moving forward. They are a very friendly and professional company with good prices, I would recommend them to anyone in need of HVAC services.

"I took advantage of the Angie's List promotional coupon for an a/c tune-up. Jake was quick to respond to my request through Angie's List and scheduled me quickly and at a convenient time. Once here, he was thorough in cleaning inside and around my A/C unit. He did the proper diagnostics and discovered that my capacitor was leaking. He offered me an excellent deal to replace it and was able to come back in two day to do so once the part came in."

"Harold and his team showed up right on time, and got to work without delay. They were clean, quick and didn’t even bat an eye at our two small children who kept asking who they were and what they were doing. They installed a new breaker box, and meter box, it looks far more clean and professional than the person/company who built our house. My husband and I highly recommend this team and will absolutely rehire them should that time come."

Install Boiler FAQs, answered by experts

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.
