"It was wonderful working with Chris/ Nextgen today. He did a great job explaining everything I need to do with my unit, what to expect, and all the benefits I can get from it. I really appreciate the time he took to answer my questions and make sure I understood everything. I just want to say thank you, Chris, for all your help! I look forward to a great installation! I’m scheduled for tomorrow"

"CB Mechanical provided exceptional service. The staff provided a level of friendliness that made me feel as though my time spent on the repairs was time spent with old friends. Charlie provided a lot of detail to his work and even double checked the repairs before completing the job. I feel as though the quality and low pricing makes them a top choice for my household. I promise you wonâ t be disappointed!"

"Chris’s crew was outstanding. They cleaned our crawlspace and didn’t encapsulated it. They were placed ductwork where it was needed. The photographs are clear documentation of a home improvement. I think the cost was reasonable to high, but I have nothing to compare to. In the end, I am quite pleased. The dehumidifiers have lowered the humidity in the living space and eliminated a musty smell that had been present. I can recommend him with no reservation."

Heating and Air Conditioning questions, answered by experts

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.

Winterizing can still help you save money on energy costs and help prepare your AC for its work next year when you turn it back on. We suggest planning for at least some maintenance, even if winters are mild in your area.

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

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.
