"New Era HVAC was amazing! I own a small business that has a very challenging environment to work around. Jared was extremely professional and minimized the disruption to our routine. We have large warehouse heaters. A few years ago we had one installed by another company. They left a huge mess, took 2 1/2 days to do the work and had no regard for disrupting our business. In contrast, when Jared replaced the second one he was done in one day, left the area clean and neat when he left, and was extremely accommodating with us. We have also had a tankless water heater replaced by New Era and had the same experience. Professional, honest, and reliable - you will not find a better company out there!!"

"Tony was very easy to work with and accommodating. I had narrowed my choice to 3 firms. Elevation was not the cheapest nor the most expensive but I felt most comfortable with Tony and believe he offered the most value. My air conditioner was installed today, I hope this will be the start of a great (and cool) relationship."

Heating and Air Conditioning questions, answered by experts

Choosing between a ductless mini-split and central AC depends on your specific needs. Ductless mini-splits are ideal for targeted cooling, providing zoned comfort and energy efficiency. They are perfect for smaller spaces or homes lacking ductwork. In contrast, central AC offers consistent cooling throughout the entire house but requires ductwork and may be less energy-efficient for smaller spaces. 

Consider factors like budget, home size, and cooling preferences to make the right choice. Combining both systems, with a ductless mini-split in specific areas, can also be a viable solution for tailored comfort and overall efficiency.

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

You can adjust uneven airflow in your home by adjusting the dampers on the vents. However, if the temperature feels consistent throughout the home, don’t worry too much about uneven airflow. Generally speaking, larger rooms should receive more airflow than smaller rooms, especially if they only have one vent.

While your AC unit may still run even if its capacitor is going bad, doing so takes a lot more energy, so it can drive up your electric bill and cause further damage to your AC unit’s parts. If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.
