Air Conditioning FAQ From Jerry Kelly Heating & Air Conditioning in St. Peters, MO & Beyond!

We’re well into summer, which means Jerry Kelly Heating & Air Conditioning’s technicians and installers have already visited many, many homes here in the St. Louis area. During our visits, homeowners ask several great questions about their air conditioning systems. Some of these questions get asked more often than others, so we thought it would be a good idea to answer some of the most frequently asked air conditioning questions here on our blog.

1. How often should I have my HVAC system serviced?

Typically, it’s recommended to have your HVAC system serviced annually, with inspections in the spring for the AC unit and in the fall for the heating system to ensure they are operating efficiently and ready for the coming season.

2. Why is my HVAC system not heating or cooling my home evenly?

Uneven heating or cooling can be caused by several issues, including ductwork problems, blocked vents, improper insulation, or an incorrectly sized HVAC system for the home.

3. How often should I replace my air filter?

It’s generally advised to replace your air filter every 30 to 90 days, depending on the type of filter, the air quality in your area, and if you have pets or allergies.

4. What is the best temperature to set my thermostat to in summer/winter?

For summer, the recommended thermostat setting is around 78°F when you’re at home and higher when you’re away. For winter, 68°F is recommended during the day, lowering it at night or when the house is unoccupied to save energy.

5. Why is my HVAC system making strange noises?

Strange noises can indicate various issues, such as loose components, debris in the system, or the need for lubrication. A professional inspection can identify and resolve the specific cause.

6. How can I reduce my energy bills while still keeping my home comfortable?

Improving insulation, sealing leaks around doors and windows, using a programmable thermostat, and ensuring your HVAC system is properly maintained can help reduce energy bills.

7. What size HVAC system do I need for my home?

The size of the HVAC system required depends on various factors, including the square footage of your home, ceiling height, insulation quality, and the number of windows. A professional HVAC contractor can perform a load calculation to determine the appropriate size.

8. Can I install a new thermostat myself?

While many homeowners can install a new thermostat themselves, it’s important to ensure compatibility with your HVAC system and to follow all installation instructions carefully. For smart thermostats, professional installation might be preferable.

9. How long does an HVAC system typically last?

The lifespan of an HVAC system varies but typically ranges from 15 to 25 years, depending on the type of system, brand, and how well it has been maintained.

10. What are the signs that I need to replace my HVAC system?

Signs include frequent repairs, increasing energy bills, uneven heating or cooling, excessive noise, and if the system is over 15 years old and not performing efficiently.
