There are a couple of things that you can check. First, is the thermostat set too low, or is the temperature turned down below the room temperature? If so, then that could be preventing your unit from turning on. If your thermostat’s batteries are more than a year old, then that could also cause a problem. It could also be an issue with the breaker, which could be tripped or turned off, or the disconnect at the outside condenser could be tripped or removed. Finally, the drain line could be clogged, and the emergency float switch could be keeping it turned off.

It’s possible that the thermostat is set too low or too high, preventing your unit from shutting off when it should. In addition, if your unit is set to ‘auto,’ it might not shut off, even when your home is at the right temperature.

It is recommended to have your HVAC system serviced at least once a year. Ideally, schedule maintenance in the spring for cooling systems and in the fall for heating systems to ensure optimal performance and identify any potential issues before they escalate.

The average lifespan of an HVAC system varies depending on factors such as usage, maintenance, and quality of installation. Generally, a well-maintained system can last 8 to 12 years, but it may need repairs or replacements over time.

Signs that your HVAC system may need repair include inadequate heating or cooling, unusual noises, frequent cycling, inconsistent temperatures, increased energy bills, and poor indoor air quality. If you notice any of these signs, it’s advisable to contact an HVAC professional for an inspection.

It is recommended to change your air filters every 1 to 3 months, depending on factors such as filter type, indoor air quality, and system usage. Regular filter changes help maintain system efficiency, improve air quality, and extend the lifespan of your HVAC equipment.

The ideal temperature setting for your thermostat depends on personal comfort preferences. However, it is recommended to set the thermostat at energy-efficient levels, such as 68-72°F (20-22°C) in winter and 72-78°F (22-26°C) in summer, to balance comfort and energy savings.

To improve energy efficiency, you can: regularly maintain your system, seal air leaks in your home, ensure proper insulation, use programmable thermostats to control temperature settings, and consider upgrading to energy-efficient HVAC equipment.

Proper HVAC system sizing ensures that your equipment is neither too large nor too small for your space. An accurately sized system helps optimize comfort, energy efficiency, and humidity control. An HVAC professional can perform calculations to determine the appropriate size for your home.

HVAC system installation is complex and requires specialized knowledge, tools, and licenses. It is strongly recommended to hire a licensed HVAC professional for system installation to ensure proper sizing, safety, and warranty compliance.

Regular HVAC maintenance provides several benefits, including improved system performance, enhanced energy efficiency, extended equipment lifespan, reduced likelihood of breakdowns, improved indoor air quality, and enhanced comfort for occupants.

To improve indoor air quality, you can: regularly change air filters, keep your home clean, control humidity levels, ensure proper ventilation, consider air purifiers, filters or dehumidifiers, and avoid indoor pollutants such as smoking or harmful chemicals.
