We're sharing the HVAC questions we are asked most often.
Do you offer emergency HVAC repair in Southern Maryland?
Yes. Assured Comfort Services offers emergency heating and air conditioning repair across Southern Maryland including Calvert, Charles, and St. Mary's counties. If your system breaks down, call (443) 971-0197 and we'll get a technician to you as quickly as possible.
What areas do you serve?
We serve all of Southern Maryland, including Calvert County, Charles County, and St. Mary's County. Our service area covers communities including Huntingtown, Prince Frederick, Waldorf, La Plata, Leonardtown, California, Dunkirk, and surrounding areas.
How often should I have my HVAC system serviced?
You should have your HVAC system professionally serviced at least once a year — ideally twice, with an AC tune-up in the spring and a heating system check in the fall. Regular maintenance prevents breakdowns, extends equipment life, and keeps your energy bills lower.
Do you service both residential and commercial HVAC systems?
Yes. We service residential homes and commercial properties throughout Southern Maryland. Our technicians are experienced with all major HVAC brands and system types, from single-family home systems to larger commercial heating and cooling equipment.
How do I know if I need HVAC repair or a full replacement?
If your system is under 10 years old and the repair cost is less than half the price of a new unit, repair is usually the better option. If your system is 15 years or older, requires frequent repairs, or is causing high energy bills, replacement is likely more cost-effective. We'll give you an honest assessment either way.
What brands of HVAC equipment do you install?
We install and service all major HVAC brands. During a consultation we'll recommend the best system for your home or business based on your budget, square footage, and efficiency goals. We'll never push a brand that isn't the right fit for your situation.
Are your technicians licensed and insured in Maryland?
Yes. Assured Comfort Services is fully licensed and insured to perform HVAC work in the state of Maryland. Our technicians are trained professionals who stay current with industry standards and equipment.
Do you install heat pumps in Southern Maryland?
Yes. Heat pumps are an excellent choice for Southern Maryland's climate, providing both heating and cooling from a single system. We install, repair, and maintain heat pumps for both residential and commercial customers, including ductless mini-split systems.
How long does an HVAC installation take?
A standard HVAC installation in a residential home typically takes one full day — usually 4 to 8 hours depending on the system type and any ductwork modifications needed. We'll give you a clear timeline during your estimate so you can plan accordingly.
Do you offer maintenance agreements?
Preventive Maintenance Agreements - Yes, we have Annual Maintenance Agreements - Cooling Season and Heating Season Inspections to make sure your system is ready for the coming Season.
Do you offer finanacing?
