Frequently Asked Questions

The smell of rotten eggs from your AC system almost always points to a gas leak that’s getting into your ductwork. Natural gas can catch fire, explode, or reduce oxygen levels in the bloodstream, resulting in severe or fatal consequences.

If you smell rotten eggs coming from your AC unit, turn off the gas supply if you can and evacuate the house immediately. Then, call 911 or your gas contractor to report the leak.

Don’t ignore a furnace that keeps shutting off too quickly. Common causes of your furnace cycling on and off (short-cycling) include:

• Low airflow
• A dirty or corroded flame sensor
• Faulty thermostat
• Blower motor issues
• Oversized furnace
• Blocked exhaust vent (flue pipe)

Don’t hesitate to contact a professional heating contractor from Master Plumbers Heating & Cooling to inspect your system as soon as you realize your furnace has an issue.

This is one of the most common FAQs we receive. Your heater may blow cool air instead of hot air for various reasons, including:

• Incorrect thermostat settings

• The heater’s pilot light has gone out
• Faulty thermostat
• Overheated furnace

• Clogged condensate drain lines

If you notice your heating system blowing cold air, contact an expert to identify the source of the issue and restore your heating.

Several things can cause your hot water supply to run out unusually fast. Common culprits are a broken dip tube, sediment buildup, or a faulty heating element. Your water heater may also run out of hot water fast because of power supply issues, rusty pipes, or a pilot light that has gone out.

If your hot water runs out faster than normal, contact your local water heater company to diagnose and fix it as soon as possible.

If you have low water pressure, start by contacting your neighbors to see if they’re experiencing a similar problem. If so, the municipal water system may have an issue. If not, do the following:

• Check to see if the main water valve is completely open
• Clear pipe clogs
• Test the water pressure
• Check your well pump
• Look out for leaks
• Replace the water pressure regulator
• Install a water pressure booster

With some research, know-how, and professional help, you can improve your water pressure in almost any scenario.
