"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).

"I needed an entire new house system with all duct work installed and lines and power. I had window units for air and baseboard for heat. Greg's team was great to work with. Always on time and very professional. Did a great job on the install and I love the system Can't even hear it run. They worked and listened to me on ideas I had on what I wanted to have done, and we worked well together to come to a final solution that worked, as some of the ducts was hard to install. Would use the Blair team anytime. P.S. Great price on the system"

"They were very good with initial response, estimate, and install date. The quality of the install was mediocre; attention to detail, not so much. They did not worry too much about cleanup after the job, several examples of that; I have un-removable black goo on my driveway. There was supposed to be a two week follow-up visit and I was going to address some of my questions and issues then but was scheduled twice and did not occur either time, no call no show the second time. I realize this all occurred during a peak time of year. The unit does work without difficulty and we are happy to have HVAC but I will probably go with another company for service and maintenance.

"I was advised by another HVAC service company that I needed to replace the condenser motor and fan on our cooling system. I was provided an estimate in excess of $1,000. So, I opted for a second opinion. I contacted Kirk Wiesman at New Climate. Kirk evaluated the unit that same day and stated that it is difficult to predict when the motor may fail. With young children in my home, I prefer to error on the side of caution and wanted the motor replaced if I could afford to do so. Kirk stated that the fan was fine and did not need to be replaced. As promised, Kirk provided later that same day an estimate to replace the motor ($393). We agreed upon a date and time for the work to be completed. Kirk showed up on time and installed a direct replacement (original equipment) motor.  Kirk explained the charges, which matched the estimate.  Kirk also explained the warranty on this work."

Install Boiler FAQs, answered by experts

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.
