 # Whether it’s an air conditioner, a water heater or a coffee maker, most manufacturers will require you to register equipment shortly after purchase in order to offer you their basic factory warranty.

Unlike a coffee maker which can be easily replaced, warranty service for major equipment requires more than a phone call to the manufacturer and voiding those warranties is easier than you might think.

When it comes to major equipment, using off-brand replacement parts or failing to use an authorized service provider for repairs and regular preventive maintenance are just a few of the things that can void your warranty and, when it comes time for warranty service, you’ll need an authorized service provider to diagnose the problem and deal with the manufacturer.

Manufacturers will often require service providers to send back a defective part so they can confirm that it is, in fact, defective and, if they determine that the replaced part was still good, the service provider will be held liable for the cost of the part, plus an additional financial penalty.

And, while the basic factory warranty will cover the cost of a warrantied part, it won’t cover the costs associated with diagnosing the problem, ordering

  # Nothing is more frustrating than having your air conditioner coil freeze up just as the temperature outside is climbing.

Coils freeze when the temperature in your evaporator coil drops too low. Moisture in the air freezes on contact, building up ice on the coil. This buildup blocks airflow and can cause your unit to fail completely.

## Why do AC coils freeze?

**Low air flow** prevents heat from being absorbed by the refrigerant in your evaporator coil. The temperature in the coil then plummets below freezing and ice accumulates. A dirty filter, malfunctioning fan or motor are possible causes of low air flow. Restrictions of any kind in your ductwork can also prevent the air from flowing across the coil.

**A faulty thermostat** can overwork your air conditioner, reducing the temperature in the coil to the point of freezing it. The unit's internal controls can also cause problems so have the entire control system checked.

**Low refrigerant pressure** results in a lower temperature in the evaporator coil as the refrigerant expands. This is typically caused by leaking refrigerant which must be repaired immediately.

## How to prevent frozen coils

**Clean and replace filters** at least four times per year to maintain airflow
