"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!"

"We have been customers of Watkins for a few years, but this is our first review on them. They are super friendly and do great work. A few years ago, they were able to help us get us a new furnace in a timely fashion when ours died in the middle of winter (it was really old). At that time, they noticed the AC was not installed correctly and not up to code (previous owner). We also knew the water heater was next to go, but were able to hold off until this year. Our new AC had a part go bad this year, but they were able to come out quick and repair pretty quick (and no charge). We are very pleased with all the work and highly recommend them!"

"My husband and I were completely satisfied with H and M Heating and Cooling. We switch from a water boiling system to a conventional furnace in October. The men were on time, professional, and did excellent work. I would highly recommend them."

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).

"We selected Blair Heating and Cooling to install a Trane Mini-split ductless AC system in our historic 100 year old house. The system has two compressors and a total of 6 indoor units. From the start, Greg Blair and his team went out of their way in suggesting ways to accomplish exactly what we wanted. His team sought our feedback on every decision made right down to the routes the outside lines took to make sure they were as integrated as possible. Even though the job was difficult as our house is a three-story brick house with terra cotta blocks in the walls and metal where you would think metal shouldn't be, all of them remained positive, helpful and really excellent. I can’t recommend Blair any higher. This is the second job they have done for us and they are definitely our only choice!!"

"Mr. Wells and his staff worked with us very closely to ensure that we have the equipment that we needed at a price that we could afford.  They provided options for our furnace, answered all types of questions, and guide us to a furnace that will not only address our immediate needs but that has the attributes that will give us a worry-free operation for another 20 years.  The installers were meticulous, enterprising, and hard workers.  They arrived on time and departed only after the unit was operating as advertised.  In addition, this furnace came with a three years maintenance agreement so twice a year Wells will stop by our home to check and tune-up our unit.  
Bottom line:  The customer service, furnace attributes, employees, warranty, service after the purchase, and price made this purchase a winning one!

Install Boiler FAQs, answered by experts

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

Propane is more cost-efficient than natural gas on a per-unit basis because it produces twice as much heat energy as an equivalent amount of natural gas. But propane is not ideal if you already have a gas line installed. The best choice for your home depends on the efficiency of your appliances and the amount of installation required of your fuel choice.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.
