Do you work with both residential and commercial HVAC systems?
Yes. We service single‑family homes, townhomes, condos, apartments, offices, retail spaces, restaurants, warehouses, churches, schools, medical facilities, and multi‑unit commercial buildings.

How do I know if I need HVAC repair or replacement?
If your system is over 12 to 25 years old, requires frequent repairs, struggles to heat or cool your home or building, produces unusual noises, or causes rising energy bills, replacement may be the better long‑term option. Newer systems offer higher efficiency, quieter operation, improved comfort, and lower operating costs.

How long do HVAC systems last?
Most HVAC systems last 12 to 20 years with proper maintenance. Heat pumps and mini splits may last longer depending on usage, installation quality, and routine care. Commercial systems may have shorter or longer lifespans depending on load and operating hours.

What is the most efficient HVAC system for Maryland homes?
High‑efficiency heat pumps, variable‑speed furnaces, and inverter‑driven mini splits are among the most efficient options for Maryland’s climate, offering excellent performance in both hot summers and cold winters.

What is the most efficient HVAC system for commercial buildings?
Commercial heat pumps, VRF/VRV systems, rooftop units (RTUs), and high‑efficiency gas heating systems are common choices depending on building size, zoning needs, and usage patterns.

Furnace Installation and Heating Questions

How do I know if I need a new furnace?
You may need a new furnace if your system is 15 years old or older, produces uneven heat, makes unusual noises, requires frequent repairs, or struggles to keep up during cold Maryland winters.

What types of furnaces do you install?
We install gas furnaces, electric furnaces, propane furnaces, oil furnaces, high‑efficiency furnaces, two‑stage furnaces, and variable‑speed furnaces.

Do you install commercial heating systems?
Yes. We install commercial furnaces, rooftop units, heat pumps, boilers, and multi‑zone heating systems for offices, retail spaces, restaurants, and industrial buildings.

What is the best furnace for Maryland homes?
High‑efficiency gas furnaces are the most common and cost‑effective option for Maryland’s winter climate.

How long does furnace installation take?
Most furnace installations are completed within one day.

Do you repair all furnace brands?
Yes. We repair all major furnace brands and models, including older systems.

What are common furnace problems in Maryland?
Common issues include no heat, weak airflow, ignition failure, short cycling, blower motor problems, thermostat issues, and uneven heating.


Heat Pump Installation and Service Questions

Do heat pumps work well in Maryland?
Yes. Modern heat pumps perform reliably in Maryland’s climate, providing efficient heating in winter and cooling in summer.

What types of heat pumps do you install?
We install ducted heat pumps, ductless heat pumps, high‑efficiency heat pumps, cold‑climate heat pumps, and variable‑speed inverter systems.

Do you install commercial heat pumps?
Yes. We install commercial heat pumps, VRF/VRV systems, and multi‑zone heat pump systems for offices, retail spaces, and multi‑unit buildings.

Are heat pumps more efficient than furnaces?
In many cases, yes. Heat pumps use less energy and provide both heating and cooling in one system.

How long do heat pumps last?
Most heat pumps last 12 to 25 years with proper maintenance.

Do heat pumps qualify for rebates?
Many Maryland homeowners qualify for incentives that reduce installation costs.

Mini Split Installation and Service Questions

What is a ductless mini split?
A mini split is a high‑efficiency heating and cooling system that does not require ductwork. It is ideal for additions, older homes, and rooms that need targeted comfort.

Where can mini splits be installed?
Mini splits can be installed in bedrooms, basements, garages, sunrooms, additions, offices, man caves, she sheds, and any space without ductwork.

Are mini splits efficient?
Yes. Mini splits use inverter technology to deliver extremely efficient, quiet, and consistent heating and cooling.

Do you repair mini splits?
Yes. We repair and install all major ductless mini split brands and systems.

Do you install commercial mini split systems?
Yes. Mini splits and multi‑zone ductless systems are common in offices, server rooms, retail spaces, and commercial additions.


Air Conditioning Installation and Cooling Questions

How do I know if I need a new air conditioner?
You may need AC replacement if your system is over 12 years old, uses R‑22 refrigerant, struggles to cool your home, or causes high energy bills.

What types of AC systems do you install?
We install central air conditioners, high‑efficiency AC systems, variable‑speed AC units, and ductless cooling systems.

HVAC Maintenance Questions

How often should I schedule HVAC maintenance?
Heating and cooling systems should be serviced once per year. Heat pumps and mini splits benefit from twice‑yearly maintenance. Commercial systems may require quarterly service depending on usage.

What does HVAC maintenance include?
Maintenance includes system inspection, cleaning, safety checks, airflow testing, electrical checks, refrigerant checks, burner cleaning, blower motor testing, and efficiency optimization.
