Is it worth it to repair a hot water heater near Montclair?

It depends on the problem the water heater is having and the age of the unit. Water heaters last about 8 - 12 years and are relatively inexpensive appliances; if your water heater is fewer than 6 years old or suffering a fairly minor breakdown a repair will make the most sense, but if it’s older than 6 years and facing a repair bill of more than half the cost to replace it just go ahead and get a new water heater.

How much does it cost to fix a home air conditioner near Montclair?

The cost to fix a home air conditioner near Montclair varies depending on the nature of the problem and the parts and labor needed to fix it. Typically, air conditioning repair costs range from $200 - $1600, with most common repairs costing around $360 on average.

Why is my AC running but not cooling my home near Montclair?

If your AC is running but not cooling your Montclair home there are a few things you can check before calling a repairman. First, check the filter and see if it needs to be replaced. Second, check the thermostat setting and make sure it is on cool and set to the desired temperature. Third, check the breaker and make sure it is turned on. If none of these things solve the problem, then you may need to call a repairman.
