Heating and air conditioning service built around Leonardtown
If your heat pumps and gas furnaces with central air has started short cycling, blowing warm air or making a noise it never used to make, you are not alone — Leonardtown generates some of the highest call volume we handle in Maryland. Hot humid summers and winter cold snaps keep both heating and cooling in regular use.
A large share of the equipment we service in Leonardtown was installed by a builder to a minimum spec. That usually means an undersized return, a cheap filter rack and a condenser sitting close to a wall.
Heating season here is November through March. A pre-season inspection catches cracked heat exchangers and failing igniters before the first real cold snap.

Leonardtown20650 HVAC questions, answered
Do you offer maintenance plans?
We do. A two-visit plan in Maryland covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.
Why is my furnace short cycling?
Short cycling in Leonardtown most often comes from a restricted airflow path — a loaded filter, a closed register, an undersized return — or from an oversized unit. It can also be a failing flame sensor or a pressure switch fault. We measure static pressure and temperature rise before concluding anything, because guessing at this one is expensive.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Leonardtown see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
How much does an HVAC service call cost in 20650?
A diagnostic visit in Leonardtown typically runs $75 to $150, and that fee is usually applied toward the repair if you approve the work. Repair prices are quoted as a flat rate before we start, so the number you approve is the number you pay regardless of how long the job takes.
What does a new system cost in Leonardtown?
A complete residential replacement in the 20650 area generally lands between $6,000 and $13,000 installed, depending on capacity, efficiency rating and how much ductwork has to be modified. We always perform a Manual J load calculation first, because an oversized unit costs more to buy and runs worse than a correctly sized one.
Do you service commercial and light commercial properties?
Yes. Around Leonardtown we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
