"We recently had the pleasure of hiring Dawson Mechanical to have a new Navien tankless water heater installed. This was a little more than a straightforward job since the water heater was being relocated from a utility closet to the garage which was about 20 feet away. From the time I made the first call to Dawson, I had a good feeling about this company. Dave came over within a few days on a Saturday to look the job over and give me an estimate. He is very knowledgeable and took the time to answer any questions we had. When the day came for the installation, a crew of 3 workmen arrived around 9:00 AM and did not stop until the job was finished around 5:00 PM. They did an excellent job, were very good about keeping everything clean and neat, and the workmanship was top notch. In short, we were very happy with everything and would not hesitate to use Dawson for our future plumbing/HVAC needs."

Heating and Air Conditioning questions, answered by experts

On average, an AC unit lasts between 10 and 20 years. However, the specific lifespan depends on the type of unit, how often it's used, the local climate, and the quality of maintenance. Central AC units typically last 12 to 17 years, while window units have a shorter lifespan of 8 to 10 years. Portable AC units last about 5 to 10 years, and ductless mini-split systems can last up to 20 years. To extend the life of your AC unit, it's important to perform regular maintenance, such as replacing filters, cleaning coils, and scheduling annual professional tune-ups.

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.

When your HVAC technician mentions recharging your home AC unit, they’re referring to the process of topping off the unit with refrigerant, so the levels are properly maintained and pressurized. Normally, a properly functioning AC unit doesn’t need additional refrigerant, but AC units can develop leaks or other problems that decrease the amount of refrigerant needed.

Trick question: There is no difference between an AC and a furnace blower motor. Whether you have central air and heat or just one of these, the same blower motor carries hot and cold air throughout the ductwork in your home. Certain systems may have separate blower motors for the AC and furnace, but each serves the same function.

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.
