Frequently Asked Questions

What brands do you service?

We service all brands.

Do you install heat pumps?

Yes we do! We even have priority access to units that qualify for tax credits up to $2000.

Do you work on geothermal units?

No, we do not.

On average how many hours does it take to replace a furnace or A/C

Replacing a furnace or air conditioner takes about 4 to 8 hours. This time frame can vary based on factors like the complexity of the installation, the condition of existing ductwork, and any additional modifications needed.

What refrigerant is used in an A/C?

The most commonly used refrigerant in modern air conditioning systems is R-410A. It has largely replaced the older R-22 refrigerant, which is being phased out due to its ozone-depleting properties. R-410A is more efficient and environmentally friendly.

How often should I change my air filter?

Air filters should be changed every 1-3 months, depending on the type of filter and your household conditions.

What is the ideal thermostat setting for comfort and energy savings?

In the summer, set your thermostat to 78°F when you’re home and higher when you’re away. In the winter, set it to 68°F when you’re home and lower when you’re away.

How often should I service my HVAC system?

It’s recommended that your HVAC system, both heating and cooling, be serviced at least once a year.

What should I do if I think I have a gas leak?

If you suspect a gas leak, immediately evacuate the area without using electrical switches, phones, or devices that might create a spark. Once safely outside, call your gas company’s emergency line or the fire department from a safe location. Only return to the building once it has been declared safe by professionals.

What HVAC issues should be fixed ASAP?

An HVAC emergency includes several critical situations such as loud banging, screeching, or grinding noises from your HVAC system, refrigerant leaks from your A/C unit, sparking or burning smells from your furnace or A/C system, and the smell of gas near your furnace or heating system. These issues require immediate attention to ensure safety.

Does my thermostat’s location matter?

Yes, thermostat location affects heating and cooling efficiency. Install it centrally on an interior wall, away from heat sources, drafts, windows, and vents. Mount it 52 to 60 inches above the floor and avoid areas with poor airflow. Proper placement ensures accurate readings, consistent temperature, and improved energy efficiency.

Does turning off your thermostat cause your HVAC system or furnace to wear out faster?

Turning off your thermostat occasionally does not typically cause your HVAC system or furnace to wear out faster. However, frequently turning the system on and off can cause more wear and tear due to the repeated cycling. It’s generally better for the longevity of your HVAC system to maintain a consistent temperature and use a programmable thermostat to adjust temperatures automatically when you’re not home.

Does turning on your HVAC system after prolonged inactivity cause any problems?

Turning your HVAC system on after a prolonged inactivity can cause issues if the system has not been correctly maintained. Dust and debris can accumulate in the system, leading to clogged filters, reduced airflow, and mechanical wear. Components like belts, bearings, and electrical connections may deteriorate over time if not regularly used or inspected. It’s advisable to have a professional inspection and maintenance performed before restarting the system.

Should I turn off my heater/thermostat when gone from the house?

Lowering the thermostat instead of turning it off completely is often the best approach to balance energy savings and home protection.

Do gas furnaces still run when the power goes out?

Gas furnaces and boilers cannot run without electricity. Gas stoves and standard (not high-efficiency) gas water heaters can still run during a power outage. Tankless water heaters will not run, and gas dryers will not run.

Do you install generators?

Yes, we install Briggs and Stratton whole-home generators. For more info you can read our buying guide.

What electrical issues should be fixed ASAP?

Exposed or damaged wiring, burning smell or smoke from electrical outlets, appliances/devices, or frequent breaker trips.

What should I do if a circuit breaker keeps tripping?

Identify the appliance causing the trip, unplug it, and reset the breaker. If the problem persists, call an electrician.

What’s the difference between a whole-home surge protector and a traditional power strip protector?

Whole-home surge protectors offer total protection for your entire electrical system, including security systems or A/C. In contrast, traditional power strip surge protectors only provide localized protection for individual devices and appliances, typically with lower surge capacity.

Why do my lights flicker?

Loose bulbs, faulty fixtures, or wiring issues can cause flickering lights. If changing the bulb does not resolve the issue, it’s best to have an electrician inspect it.

Are tankless water heaters gas or electric?

Tankless water heaters can be either gas or electric. Here at Peterman we only install gas, Navient, models.

How can I prevent my pipes from freezing in the winter?

Insulate pipes, keep cabinet doors open to allow warm air to flow, and let faucets drip slightly to prevent freezing. For more information, check out our blog.

How do I know if I have hard water?

o determine if you have hard or soft water, you can observe how well soap lathers (hard water doesn’t lather well), check for white deposits on faucets and appliances or use a commercial test kit with color-changing strips. You can also contact your local water supplier for a water quality report or hire a professional for detailed testing. To learn the best ways to combat against hard water, check out or blog.

How often should I get my plumbing system checked?

It’s generally recommended that your plumbing system be inspected once every one to two years. This frequency can help ensure everything is running fine and prevent costly repairs in the future by catching issues early.

Should someone have a water softener if they have a tankless water heater?

A water softener with your tankless water heater is a good idea. It stops hard water minerals from causing scale build-up, keeps your heater running efficiently, and helps it last longer. Plus, it ensures a steady water flow and can save you money on energy bills.

What are the signs of a water leak?

Water leaks can sometimes be identified by unusually high water bills, damp spots, mold growth, and the sound of running water when no fixtures are in use.

What is the life expectancy of a tankless water heater?

A tankless water heater’s life expectancy is typically around 20 years. With proper maintenance, some units can last even longer. Regular maintenance includes descaling to prevent mineral build-up, which can help extend the unit’s lifespan

What plumbing issues should be fixed ASAP?

A burst pipe, sewage backing up in your home, no water supply, or an overflowing toilet that will not stop.

What voltage/power do you need for a tankless water heater in your home?

For electric tankless water heaters, you’ll need 240 volts (normal house power) and between 50 to 200 amps, possibly requiring dedicated circuits. Gas tankless heaters need a standard 120-volt circuit for controls and ignition, along with a proper gas supply and venting.
