"My experience with Clean Air Genie was great. They were professional and knowledgeable explaining everything to me clearly and provided pictures and videos before and after the work was done. My air ducts were pretty bad (hadn’t been cleaned in 10 years) and they were able to get them very clean and sanitized. I appreciate that their prices were transparent and fair for the work. I will definitely recommend!"

"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!!"

Heating and Air Conditioning questions, answered by experts

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.

If you’re planning an AC replacement, choosing an AC with a higher SEER rating may save you money in the long run. Tax credits could cover as much as 30% of the job, and you’ll notice smaller utility bills (particularly if you live in a hot climate where you need to constantly run the AC). Generally, you can expect to pay between $350 and $1,500 for each SEER rating increase. Weigh the cost against your typical utility bill to figure out what’s worth it to you.

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.
