Repair vs. Replacement FAQs

How Do I Know If I Should Repair or Replace My HVAC System?

Consider replacement when your system is nearing the end of its typical lifespan, needs frequent repairs, or requires a repair costing about half the price of a new system. One of our technicians can compare repair and replacement costs for your equipment. Request an estimate to get started.

How Long Does an HVAC System Last in Maryland?

Gas furnaces typically last 15 to 20 years, while air conditioners and heat pumps typically last 10 to 15 years. Regular preventative maintenance helps equipment reach the upper end of those ranges.

What Are the Signs My Furnace Is Failing?

Common warning signs of a failing furnace include:

• Age of 15 years or more
• Rising energy bills with no change in use
• Uneven heating from room to room
• Banging, rattling, or squealing noises
• Frequent cycling on and off
• More frequent repairs

If you smell gas or your carbon monoxide alarm sounds, leave your home and call 911 first. Otherwise, schedule service and we’ll take a look.

Why Is My AC Running but Not Cooling My Home?

Common causes include a dirty air filter, incorrect thermostat settings, a dirty outdoor unit, a frozen evaporator coil, low refrigerant due to a leak, or a failed electrical component. Replace a dirty filter and check your thermostat first. If the air is still warm, turn off the system to prevent damage, then call us for air conditioning repair.

How Much Does a New HVAC System Cost?

Cost depends on the system type, size, efficiency level, condition of your ductwork, and installation complexity. Because every home is different, we provide a customized estimate instead of a one-size-fits-all price. Request an estimate, and ask about financing and current specials.

How Long Does an HVAC Installation Take?

Many standard replacements of an existing system take one to two days. Projects involving new ductwork, multiple ductless units, a boiler, or a geothermal heat pump can take longer. We’ll review the timeline with you before work begins.

Heating System FAQs

How Does a Heat Pump Work?

A heat pump moves heat instead of creating it. In winter, it pulls heat from outdoor air and brings it inside. In summer, it reverses to remove heat from your home, so one system provides both heating and cooling. Learn more about our heat pump services.

Do Heat Pumps Work in Maryland Winters?

Yes. Modern heat pumps, especially cold-climate models, are designed to heat efficiently at low temperatures, and Maryland winters are moderate enough for them to perform well. Some homes pair a heat pump with a gas furnace as a dual-fuel system for added backup on the coldest days. We can recommend the right setup for your home.

What Is the Difference Between a Heat Pump and a Furnace?

A furnace creates heat by burning fuel such as natural gas or oil, while a heat pump uses electricity to move existing heat. A heat pump heats and cools with one system and can be very efficient, and a furnace delivers strong heat in any outdoor temperature. The best choice depends on your home, fuel availability, and budget. 

What Is a Dual-Fuel System?

A dual-fuel system pairs an electric heat pump with a gas furnace. The heat pump handles heating in milder weather, and the furnace takes over when temperatures drop low enough that gas is more efficient or comfortable. This balances comfort, efficiency, and operating cost.

How Does a Boiler Differ From a Furnace?

A boiler heats water (or makes steam) and sends it through pipes to radiators, baseboard units, or in-floor radiant heat. A furnace heats air and distributes it through ductwork. Boilers don’t need ducts, so they’re common in homes without them. Learn more about boilers.

What Is a Geothermal Heat Pump?

A geothermal heat pump, also called a ground-source heat pump, uses the stable temperature of the earth beneath your property to heat and cool your home. It can deliver high efficiency year-round. Bay Breeze offers geothermal heat pump services, including installation, maintenance, and repair.

Ductless Systems and Ductwork FAQs

What Is a Ductless System, and When Does It Make Sense?

A ductless system uses a small outdoor unit connected by a refrigerant line set to one or more indoor units mounted in your rooms, so no ductwork is needed. Heat pump models both heat and cool. Ductless systems work well for additions, older homes without ducts, and rooms that are hard to keep comfortable. 

How Do I Know If My Ductwork Needs Repair or Cleaning?

Signs your ductwork needs attention include:

• Rooms that stay too hot or too cold
• Excess dust around vents
• Higher energy bills
• Visible damage, gaps, or disconnected sections
• Musty odors when the system runs

Leaky or damaged ducts waste energy and can spread dust through your home. Learn more about our air duct services.

Indoor Air Quality FAQs

What Is Indoor Air Quality, and Why Does It Matter?

Indoor air quality (IAQ) describes how clean and healthy the air inside your home is. Dust, pollen, pet dander, humidity, and volatile organic compounds (VOCs) can all affect it. Because modern homes are tightly sealed, your HVAC system plays a big role in filtering and circulating air. See our indoor air quality services.

What Is an Air Scrubber, and How Is It Different From a Filter?

An air scrubber is a whole-home air treatment device installed in your HVAC system. A filter physically traps particles as air passes through, while an air scrubber such as the Air Scrubber Plus from Aerus works to reduce airborne contaminants and odors. Many homes benefit from both. See our air scrubber page and our article on how air purifiers and air filters work.

How Often Should I Change My Air Filter?

Standard 1-inch filters generally need replacing every 1 to 3 months, and thicker media filters every 6 to 12 months, depending on the manufacturer’s guidance. Check your filter monthly, and change it more often if you have pets, allergies, or a dusty home.

Can HVAC Help With Allergies or Dust?

Yes. Better filtration, whole-home air treatment such as an air scrubber, humidity control, and clean ductwork can reduce dust and other airborne particles that bother allergy sufferers. On-schedule filter changes and regular maintenance matter too. Talk with our team about options for your household.

Maintenance and Savings FAQs

How Often Should I Have My Furnace and AC Serviced?

Have your AC serviced once a year, ideally in spring, and your furnace or boiler once a year, ideally in fall. Heat pumps run year-round, so they benefit from two checkups a year. Priority Comfort Club members receive two checks per year.

What Happens During an HVAC Tune-Up?

During a tune-up, a technician inspects, cleans, and tests the key parts of your system to catch small problems before they become breakdowns. Our Priority Comfort Club includes a 21-point inspection. Schedule a tune-up before the heating or cooling season begins.

What Is the Priority Comfort Club?

The Priority Comfort Club is Bay Breeze’s HVAC maintenance membership. It comes in Silver, Gold, and Platinum tiers, plus a Mitsubishi ductless-only plan. Every plan includes a 21-point inspection, two checks per year, and priority service. Higher tiers add more coverage and bigger discounts, so benefits vary by plan. Optional add-ons, such as filters and condensate pump coverage, are also available. Compare plans and enroll on our Priority Comfort Club page.

Does Preventative Maintenance Really Prevent Breakdowns?

It lowers the risk significantly. Preventative maintenance catches worn parts, dirty components, and small leaks early, helps your equipment run efficiently, and extends its life. It can’t stop every failure, but it costs far less than emergency repairs.

What Should I Set My Thermostat to for Comfort and Savings?

The U.S. Department of Energy suggests setting the thermostat to about 68°F in winter when you’re home and awake, and about 78°F in summer when you’re home, with adjustments when you’re asleep or away. A programmable or smart thermostat can automate these settings. Read our article on thermostat settings for comfort and savings.

What Do SEER2 and AFUE Ratings Mean?

Seasonal Energy Efficiency Ratio 2 (SEER2) measures how efficiently an air conditioner or heat pump cools over a season, and higher numbers mean greater efficiency. Annual fuel utilization efficiency (AFUE) measures how much of a furnace’s or boiler's fuel becomes heat, so a 95% AFUE means about 95% of the fuel is converted to heat. Higher ratings usually cost more up front but less to operate.

How Can I Lower My Heating and Cooling Costs?

The most effective steps are:

• Schedule regular maintenance for your system
• Change air filters on time
• Use thermostat settings that fit your schedule
• Seal and repair leaky ducts
• Improve insulation and air sealing
• Replace aging equipment with energy-efficient models

Request an estimate if your system is nearing the end of its life.
