Have questions about keeping your home cool and comfortable? We’ve gathered answers to the most common air conditioning maintenance, repair, and installation questions to help you make the best decisions for your system.
AC Maintenance FAQs
How often should I have my air conditioning system serviced?
We recommend having your AC professionally maintained once a year, ideally in the early spring before the intense New Jersey summer heat kicks in. Regular tune-ups keep your system running efficiently, lower your energy bills, and catch minor issues before they turn into costly mid-summer breakdowns.
What is included in a Mann's Heating and Air Conditioning AC safety and maintenance check?
Our comprehensive maintenance check covers everything needed to optimize your system, including:
- Cleaning the outdoor condenser coils.
- Checking refrigerant levels and pressure.
- Inspecting and tightening all electrical connections.
- Testing the thermostat operation and calibration.
- Checking the condensate drain for blocks.
- Inspecting the ductwork for visible leaks.
- Replacing or cleaning your standard air filters.
Do you offer seasonal service agreements?
Yes! We believe in preventing emergencies before they happen. We offer seasonal service agreements that include regular precision tune-ups, priority scheduling, and discounts on repairs. It’s the easiest way to ensure your comfort system runs at its best all year round.
AC Service and General Questions
How often should I change my home's air filters?
For standard 1-inch pleated filters, we recommend changing them every 30 to 90 days. If you have pets, allergies, or smoke in the home, you will want to check them monthly. Clean filters keep air flowing freely, which prevents your system from overheating and improves your indoor air quality.
Does cleaning my air ducts actually help my AC run better?
Absolutely. Over time, dust, dander, and debris build up inside your ductwork. This buildup restricts airflow, forcing your AC to work much harder to cool your home, which increases energy wear and tear. Professional duct cleaning ensures clean, unobstructed airflow and maximizes system efficiency.
AC Repair FAQs
What are the signs that my air conditioner needs a repair?
You should call a professional if you notice any of the following:
- Blowing warm air: The system is running, but the air coming from the vents isn't cold.
- Frequent cycling: The AC turns on and off constantly without properly cooling the space.
- Strange noises: Squealing, grinding, or banging sounds from the indoor or outdoor unit.
- Unusual odors: Musty or burning smells when the system turns on.
- Water leaks: Pooling water around your indoor furnace/air handler or dripping from the ceiling.
Why is my AC running but not cooling my house?
This common issue is usually caused by a few specific culprits: a severely clogged air filter blocking airflow, a tripped breaker to the outdoor condenser unit, a failing compressor, or a refrigerant leak. Turn the system off to prevent damage and give us a call to diagnose the exact issue.
Do you provide emergency AC repair services?
Yes. We understand that a broken AC in the middle of a New Jersey heatwave is a major safety concern. We offer 24/7 emergency service to get your cooling system back up and running as quickly as possible.
AC Replacement and Installation FAQs
How long does a typical central air conditioning system last?
On average, a well-maintained central air conditioner lasts between 15 to 20 years. If your system is approaching or past the 15-year mark and requires frequent repairs or runs up high electric bills, it is likely time to consider a replacement.
What are the benefits of replacing my old system with a new Carrier® unit?
As a Carrier Factory Authorized Dealer, we install some of the most reliable, whisper-quiet, and energy-efficient systems on the market. Replacing an old system gives you:
- Significantly lower monthly energy bills thanks to higher SEER2 (efficiency) ratings.
- Enhanced indoor humidity control and consistent temperatures.
- Modern smart thermostat compatibility.
- Peace of mind with excellent manufacturer warranties.
Do you offer financing options for new AC installations?
Yes, we understand that a new HVAC system is a significant investment for your home. We offer convenient financing options through Payzer, allowing you to apply online easily, get quick approvals, and split the cost into manageable monthly payments.
Heating Maintenance FAQs
When should I schedule my annual heating system maintenance?
We highly recommend scheduling your heating tune-up in the early fall, before you turn the system on for the first season. Getting your furnace or boiler checked in September or October ensures it runs safely and efficiently all winter long, preventing sudden breakdowns on the coldest days of the year.
What exactly do your technicians do during a heating safety check?
Because heating systems rely on combustion or high electrical loads, our maintenance is focused heavily on safety and efficiency. A typical Mann’s tune-up includes:
- Checking the heat exchanger for dangerous cracks or corrosion.
- Testing for dangerous carbon monoxide (CO) leaks.
- Inspecting and tightening all electrical connections.
- Cleaning and adjusting the burners and ignition assembly.
- Inspecting the flue pipes and venting system for blockages.
- Checking and tightening all electrical wiring and safety controls.
- Testing the thermostat for proper operation.
- Replacing standard air filters.
Can routine maintenance really save me money on my heating bills?
Yes, absolutely. Dust, dirt, and neglected components force your system to run longer and work harder to heat your home, which spikes your gas or electric bills. Regular maintenance keeps your system running at peak efficiency, which can lower your monthly heating costs by up to 15%.
Heating Service & General Questions
What is the difference between a furnace, a boiler, and a heat pump?
This is a common point of confusion for homeowners:
- Furnaces heat air and blow it through ductwork and registers throughout your home.
- Boilers heat water and send steam or hot water through pipes to radiators or baseboard heaters.
- Heat Pumps are all-electric systems that pull heat from the outside air to warm your home in winter (and reverse the process to cool it in summer). Mann's provides expert service and installation for all three types of systems.
Why is my home so dry when the heat is running, and how can I fix it?
As heating systems warm the air in your home, the relative humidity drops drastically. This causes dry skin, static electricity, and irritated sinuses. We can install a whole-house humidifier directly into your ductwork to add controlled, comfortable moisture to your air all winter long.
Do you service oil-to-gas heating conversions?
Yes, we do! Many Central New Jersey homeowners are switching from old oil systems to cleaner, more cost-effective natural gas lines. We handle the entire process—from removing the old equipment to installing a highly efficient modern Carrier gas furnace or boiler.
Heating Repair FAQs
What are the signs that my heating system needs a repair?
Do not wait for your heat to shut off completely. Call us if you notice any of these warning signs.
- Yellow or flickering burner flame: On a gas furnace, the flame should always be a steady, crisp blue. A yellow flame can indicate incomplete combustion and a carbon monoxide hazard.
- Frequent cycling: The system turns on and off every few minutes without reaching your thermostat setting.
- Cold spots: Some rooms are freezing while others are boiling hot.
- Loud noises: Clanking, banging, or persistent squealing noises from your unit.
My furnace is blowing cold air. What should I check before calling you?
Before you call for emergency service, check these three quick things:
- Make sure your thermostat is actually set to "Heat" and the temperature is set higher than the room's current temperature.
- Check your air filter. A completely clogged filter restricts airflow, causing the furnace to overheat and safety switches to shut off the burners, leaving only cold air blowing.
- Check your electrical panel to ensure the breaker for the heating unit hasn't tripped.
What should I do if my heat goes out in the middle of a winter night?
Don’t panic. Wrap up in warm layers, keep your doors closed to lock in residual heat, and call Mann’s immediately at (732) 442-6640. We offer 24/7 emergency heating repairs across Middlesex, Monmouth, Somerset, and Union counties to ensure your family stays safe.
Heating Replacement & Installation FAQs
How many years can I expect my furnace or boiler to last?
Typically, a well-maintained gas furnace lasts between 15 to 20 years, while a high-quality boiler can last 20 to 25 years. If your system is within this age range and requires frequent repairs or makes your energy bills skyrocket, replacing it is usually the more cost-effective choice.
What are the advantages of upgrading to a high-efficiency Carrier® heating system?
As a Carrier Factory Authorized Dealer, we offer systems with AFUE (Annual Fuel Utilization Efficiency) ratings up to 98%. This means 98% of the fuel you pay for is converted directly into heat for your home, with almost zero waste. Upgrading gives you lower utility bills, whisper-quiet operation, and a reliable manufacturer's warranty.
