A new air conditioner with a basic SEER of 14 costs, on average, between $3,200 and $4,200. It is crucial to realize that the cost of replacing your AC can vary significantly depending on your specific needs and personal preferences.
A bad capacitor is the most common air conditioning repair. Find your outside unit (condenser) and check it out if your thermostat appears to be functioning properly but the air coming from your vents is simply not cold. The fan motor and the compressor are the two parts. Both are audible to a trained ear. The compressor is like a deep buzz, like a refrigerator running, and the fan naturally makes a whirring noise. Your hand should feel warmer than the ambient air when you hold it above the fan. There is a good chance that your capacitor is damaged if the outside unit is buzzing or humming but nothing is turning or blowing.
The average price to replace a water heater, including the cost of the new unit and labor, is $1,200. Bargain hunters can complete the task for as little as $815 at the low end. High-end systems can run as much as $10,000 or more, depending on the type of water heater, where it will be installed, and other factors.

He just called to say the water heater was making a very loud noise and was leaking in the catch pan. This is his interpretation so I’ll let the pros have a look.
