Expert answers most common HVAC and plumbing questions.
Why is my energy bill so high?
High bills often result from: poor insulation, air leaks, inefficient equipment (over 15 years old), incorrect thermostat settings, or duct leaks (losing 20-30% of conditioned air). Port Washington’s climate makes systems work harder. An energy audit identifies savings. New high-efficiency systems can reduce costs by 20-40%.
When should I call for emergency HVAC/plumbing service?
Should I cover my outdoor AC unit in winter?
Why is my AC running but not cooling properly?
