FAQ

HVAC Questions

What areas do you serve in Maryland?
Mechanical and Gas Services LLC provides HVAC installation, repair, and maintenance throughout Harford County and Baltimore County, Maryland, plus surrounding areas. We serve both residential and commercial customers.
How often should I service my HVAC system?
Most HVAC systems should be professionally serviced twice per year: once in spring before AC season and once in fall before heating season. Annual preventative maintenance extends equipment life, lowers utility bills, and catches small problems before they cause emergency breakdowns.
How long does a furnace or AC unit typically last?
A well-maintained gas furnace lasts 15 to 20 years on average. Central AC systems last 12 to 17 years. Heat pumps last 10 to 15 years. Lifespan depends on installation quality, maintenance frequency, and how hard the system is run during peak seasons.
Should I repair or replace my old HVAC unit?
A common rule: if a single repair costs more than half the price of a new unit, or if the system is over 12 years old and needing frequent repairs, replacement is usually the better long-term value. We provide free estimates so you can compare both options before deciding.
Do you offer free estimates?
Yes. Mechanical and Gas Services LLC provides free, no-obligation estimates for new HVAC installations and replacements throughout Harford County and Baltimore County, MD. Call 443-865-6021 or submit a service request online.
Are you licensed and insured?
Yes. Mechanical and Gas Services LLC is a fully licensed and insured HVAC contractor in Maryland. Our team carries 90+ years of combined HVAC experience across residential and commercial systems.
Do you handle commercial HVAC work?
Yes. We service light commercial HVAC systems alongside our residential work, including rooftop units, commercial water heaters, ductwork, and seasonal maintenance contracts.
How quickly can you respond to an HVAC emergency?
Response time depends on current schedule and weather demand, but our team is known for fast turnarounds: customers regularly report same-day or next-day service. Call 443-865-6021 to discuss your situation.
