Understand your system before you spend money on it.

Plain-language guides from Prestige. We believe informed homeowners make better decisions, and we'd rather explain than sell.

Heating

No heat: what to check first

  1. Thermostat on Heat, set a few degrees above room temperature, with fresh batteries.
  2. Furnace power switch on. It usually looks like a light switch near the unit.
  3. Breaker not tripped.
  4. Filter not clogged. A blocked filter can trip safety switches.
  5. Furnace door fully closed. Many furnaces won't run with it open.

If you smell gas or your CO alarm sounds, leave the home and call your gas utility or 911 first. Then call us.

Decisions

Repair or replace?

A common rule of thumb: multiply the system's age by the repair cost. Under about 3,000, repair usually makes sense. Over about 5,000, replacement is worth a serious look. It's only a starting point. Safety, efficiency and how the rest of the system is holding up matter too.

A rule of thumb, not a quote. We'll give you both options with real numbers.

Maintenance

Filters, explained

Check your filter monthly and replace it when it looks gray or clogged. Higher-rated filters capture more particles but can restrict airflow on systems that weren't designed for them. If you want better filtration, we'll check that your system can handle it.

Heat pumps

Heat pumps in winter

Steam and short defrost cycles are normal. An outdoor unit that stays caked in ice, or aux heat that never shuts off, is not. Both cost you money and are worth a call.

Cooling

Why AC coils freeze

Ice forms when the coil gets too cold, usually from low airflow (dirty filter, closed vents, dirty coil) or low refrigerant. Turn cooling off and run the fan to thaw it, then have it checked. Running a frozen system can damage the compressor.

Maintenance

Is maintenance worth it?

Seasonal tune-ups catch weak capacitors, dirty flame sensors and clogged drains before they leave you without heat or AC. They also give you a record of your system's condition. That's the idea behind Prestige Care.
