Two visits a year beat one emergency.
Your system works hardest in July and January. The maintenance plan catches small problems in spring and fall, before they turn into a breakdown during the first heat wave or cold snap.
About the planSpring visit
Before the summer heat: cooling tune-up, full inspection and cleaning.
Fall visit
Before the cold sets in: heating tune-up, full inspection and cleaning.
Priority scheduling for plan members. You don’t have to already be a customer to join.

Straight answers
HVAC questions, answered.
Repair or replace, heat pumps in a valley winter, oil furnaces, humidity, refrigerant rules and licensing in Pennsylvania, Maryland and West Virginia.
All 39 answersHow do I know if my HVAC system should be repaired or replaced?
Replacement usually makes sense when the system is 12 to 15 years old or more and you’re calling for repairs more than once a year. Climbing energy bills, rooms that are hot or cold no matter what, and new banging, rattling or grinding noises point the same way.
One repair on a younger system is usually worth doing. A string of repairs on an old one often adds up to more than a new system would have cost.
Do heat pumps work in Cumberland Valley winters?
Yes. Modern heat pumps perform well in the climate of south-central Pennsylvania, western Maryland and the Eastern Panhandle, where most winter days are above the temperatures that challenge them. On very cold nights, especially in the single digits or below, a backup heat source or a hybrid system picks up the slack.
Sizing matters most: a heat pump sized for the house keeps up during peak winter demand; one that’s undersized leans on backup heat far more often.
What is a ductless mini split?
A mini split is a heating and cooling system that connects an outdoor unit to one or more indoor units through a small line, with no ductwork needed. Each indoor unit has its own control.
They’re made for the rooms your ductwork forgot: additions, sunrooms, finished attics and basements, garages, and older homes where running ducts would mean tearing into walls.
What indoor humidity level is comfortable?
For most homes, roughly 30% to 50% relative humidity is comfortable and healthy. In winter, aim toward the lower end on very cold days to avoid condensation on windows.
Above about 60% for long stretches, mold, dust mites and musty smells become more likely.
How often should my HVAC system be serviced?
Twice a year: once in spring before cooling season and once in fall before heating season. That’s when the system is about to work its hardest, and when small problems are cheapest to catch.
Heat Cool and Happy’s maintenance plan is built around exactly those two visits for $100 a year.
What should I do if I smell gas?
Leave the house right away. Don’t flip light switches, use the phone, or start a car in an attached garage. Once you’re outside and away from the house, call your gas utility or 911.
Don’t go back in until the utility or fire department says it’s safe. After that, call your HVAC contractor to check the equipment.
