"I was contacted right away and they were at the house within an hour of my returning their call. They knew exactly what to do, had all the right equipment and were very knowledgeable about duct cleaning. The job was diagnosed, and completed in 30 minutes which included leaving the work site neat and clean. Great job!"

"I scheduled cleaning of my heating air ducts and also my dryer vent. The team arrived when scheduled and provided excellent service. The estimate provided was accurate and the time-frame was adhered to. They gave me update photos to show any problem areas and before & after pictures. They were respectful of my property and left every area where they worked in my house spotless. I couldn't be more happy with my entire experience."

"We needed to replace a patch of our living room ceiling due to damage from a water leak upstairs. We contacted C&B, who responded and quoted us a price quickly. The price was fair for a multi-day job, they got it done within a week, and they even helped us repaint the ceiling. Very professional, courteous, and trustworthy. We'd strongly recommend!"

Air Conditioning FAQs, answered by experts

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees. 

Running a window air conditioner unit costs about $0.06 to $0.88 per hour. Choosing the correct size air conditioner can help it run more efficiently.

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.

In most cases, homeowners insurance will cover an AC replacement if it was damaged due to a covered peril—such as theft, fire, or storms. So, if your air conditioner needs replacing due to regular wear and tear, your insurance company probably won’t pay for a new one. However, home warranties often cover HVAC repairs and replacements.
