What temperature should I set my thermostat in summer and winter?
The U.S. Department of Energy suggests setting your thermostat to 78°F during the summer and 68°F during the winter for comfortable conditions while optimizing energy efficiency.

Why is my air conditioner not cooling properly?
Potential reasons include low refrigerant levels, a clogged filter, a malfunctioning compressor, or issues with the thermostat. It may require a professional assessment for a more accurate diagnosis.

How can I improve my HVAC system’s efficiency?
To improve efficiency, ensure regular maintenance, clean or replace filters, seal any leaks in ducts, and consider investing in a programmable thermostat to optimize heating and cooling schedules.

What is the lifespan of an HVAC system?
On average, an HVAC system can last between 15 to 25 years, depending on the type, maintenance, and usage. Regular maintenance can extend the life of your system.

What are signs that my HVAC system needs repair?
Signs include unusual noises, inconsistent temperatures, high energy bills, increased humidity levels, and frequent cycling on and off. These indicators may suggest underlying issues that require professional attention.

Is it normal for my HVAC system to run all the time?
While systems may run longer in extreme temperatures, constant operation may indicate a problem, such as an undersized unit or poor insulation. A thorough inspection may be necessary to determine the cause.

What should I do if my heater is blowing cold air?
First, check the thermostat settings. If everything appears set correctly, inspect the air filter for clogs. If the issue persists, contact a professional for further diagnosis, as it may be a furnace or ductwork problem.

How can I reduce humidity in my home during the summer?
Use air conditioners, dehumidifiers, and exhaust fans to help reduce humidity levels. Ensuring proper ventilation and sealing any leaks can also help maintain comfort during humid months.

What should I consider when replacing my HVAC system?
Consider factors such as system efficiency ratings (SEER for cooling, AFUE for heating), the size of your home, your budget, and additional features like smart thermostats or zoning systems for better control.

How do I know if I need a new HVAC system?
Signs you may need a new system include frequent repairs, a system over 15 years old, declining energy efficiency, or an inability to keep your home comfortable. Consult a professional for a thorough evaluation.

What maintenance should I perform on my HVAC system?

Why should I perform maintenance on my HVAC system?

Heating and cooling systems work incredibly hard to perform their functions for your household. The constant stopping, starting and continual operation can wear down a machine quickly and unexpectedly if the proper care and maintenance is delayed. However, by performing preventive maintenance, or servicing your system regularly, you can maximize the lifecycle of your heating or cooling unit and guard against many unexpected failures. Preventive maintenance inspections performed on a regular basis can uncover leaks, rust, rot, soot, frayed wires and corroded electrical contacts.
