FREQUENTLY ASKED QUESTIONS

Welcome to our FAQ page! Here, we’ve compiled the most common questions we receive from homeowners and business owners in Morgantown, WV, about heating, ventilation, and air conditioning (HVAC) systems. Whether you're a first-time homeowner or just looking for some maintenance tips, we’ve got you covered.

1. How can I extend the life of my HVAC unit?

To ensure that your HVAC system runs efficiently and lasts for many years, regular maintenance is key. Here are some steps you can take:

Regularly Replace or Clean Air Filters: Dirty filters restrict airflow and force the system to work harder. Change filters every 1-3 months, depending on the season and usage.
Schedule Professional Maintenance: Have a licensed HVAC technician inspect and service your unit at least once a year. This includes checking refrigerant levels, cleaning coils, and testing system components.
Keep Vents and Ducts Clean: Ensure that vents are unobstructed by furniture, curtains, or dust. Dirty ducts can reduce air quality and efficiency.
Seal Air Leaks: Ensure that your home is well-insulated and that windows and doors are sealed properly to prevent heat loss or gain.

2. What are the signs that my HVAC unit needs repair?

Knowing when your HVAC unit isn’t performing properly can save you money on major repairs later. Here are some common signs:

Strange Noises: Grinding, rattling, or buzzing sounds can indicate loose or worn parts.
Inconsistent Temperature: If some rooms are too hot or cold, or the temperature fluctuates constantly, your HVAC system may need a tune-up.
High Energy Bills: A sudden increase in energy costs can be a sign that your unit is working harder than it should.
Weak Airflow: If the airflow from vents is weak, there could be a blockage or issue with the blower fan.
Frequent Cycling: If your unit constantly turns on and off (short cycling), it could indicate a problem with the thermostat, filter, or coils.

If you notice any of these signs, it’s a good idea to call a professional to diagnose and fix the issue before it becomes more costly.

3. How do I prepare my HVAC system for winter and summer?

Maintaining your HVAC system before the extreme weather hits is crucial for comfort and efficiency. Here’s what you need to do:

Preparing for Winter (Heating Season)

Replace the Air Filter: Make sure your filter is clean before you switch on the heater for the first time.
Check the Thermostat: Test the thermostat to ensure it’s calibrated properly. If you have a programmable thermostat, set it to optimize energy use.
Inspect the Furnace: Ensure your furnace is clean and working properly. Consider having it professionally cleaned and checked to avoid breakdowns during the cold months.
Seal Windows and Doors: Cold air drafts can make your HVAC system work harder. Use weather stripping or caulk to seal any gaps around windows and doors.
Clear the Area Around the Outdoor Unit: If you have a heat pump or outdoor condenser unit, remove any leaves, branches, or debris from around it to ensure optimal airflow.

Preparing for Summer (Cooling Season)

Replace or Clean the Air Filter: Just like in winter, a clean air filter is essential for your system’s efficiency.
Clean the Coils: Over time, dust and dirt can accumulate on the evaporator and condenser coils, reducing efficiency. Cleaning the coils improves airflow and system performance.
Inspect the Condenser Unit: Clear away any leaves, dirt, or debris around the outdoor unit to allow for better heat exchange. Check that the unit is level and not tilted.
Check Refrigerant Levels: Low refrigerant levels can impact the performance of your AC. If you suspect a refrigerant leak or your air conditioner is not cooling properly, call a professional to inspect it.
Test Your AC: Before the hot days arrive, turn on your AC to ensure it’s working properly. This helps identify potential issues before they become major problems.

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

We recommend scheduling a professional HVAC inspection and tune-up at least once a year. For your heating system (furnace or heat pump), a fall maintenance check before the cold season is ideal. For your cooling system (air conditioner), spring is the perfect time for a pre-season check-up.

Regular maintenance helps improve system efficiency, reduce the risk of unexpected breakdowns, and extend the lifespan of your unit.

5. Can I maintain my HVAC system myself, or do I need a professional?

While there are basic maintenance tasks that homeowners can do, like changing filters, cleaning vents, and checking the thermostat settings, most HVAC maintenance should be left to a professional. HVAC systems involve electrical components, refrigerant lines, and complex mechanical parts that require specialized training and equipment.

Performing DIY repairs or maintenance without the proper knowledge can lead to costly mistakes or safety hazards. For anything more than basic upkeep, it's best to call a licensed HVAC technician.

6. How can I improve indoor air quality in my home?

Improving indoor air quality is important for both your health and the efficiency of your HVAC system. Here are a few simple tips:

Change Filters Regularly: As mentioned, replace or clean filters every 1-3 months.
Install an Air Purifier: An air purifier with a HEPA filter can help remove dust, pollen, pet dander, and other allergens from the air.
Use a Humidifier: In the winter, dry air can lead to respiratory discomfort. A whole-home humidifier connected to your HVAC system can help maintain a comfortable humidity level.
Ventilate Your Home: Opening windows or using exhaust fans in high-moisture areas like kitchens and bathrooms helps prevent mold and keeps air fresh.
Keep Ducts Clean: Consider having your ducts cleaned every 3-5 years to remove dust, mold, and other contaminants.

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

Choosing the right size HVAC unit is crucial for both comfort and efficiency. A system that’s too small won’t be able to cool or heat your home effectively, while one that’s too large will cycle on and off frequently, wasting energy and causing wear and tear.

The best way to determine the right size is to schedule a load calculation with a professional HVAC technician. They’ll assess your home’s square footage, insulation, window sizes, and other factors to recommend a system that’s the perfect fit for your needs.

8. Why is my HVAC system blowing warm air in the winter or cold air in the summer?

There could be several reasons for this issue:

Thermostat Settings: Ensure that the thermostat is set to "heat" or "cool" as appropriate. Sometimes, a simple adjustment can fix the problem.
Dirty Filters: Clogged filters can restrict airflow and cause improper heating or cooling. Change your filter regularly to avoid this.
Refrigerant Issues: In cooling mode, if there’s a refrigerant leak, your AC may blow warm air. In heating mode, a malfunctioning heat pump or furnace could cause similar issues. Call a professional to inspect the refrigerant and system.
System Malfunction: If these steps don’t resolve the issue, your HVAC system may have a mechanical failure that requires a technician’s attention.

9. How can I save money on my heating and cooling bills?

Here are some tips to help reduce your energy bills while keeping your home comfortable:

Use a Programmable Thermostat: Program your thermostat to lower the temperature at night or when you’re away from home.
Seal Leaks: Insulate windows, doors, and attics to keep warm or cool air from escaping.
Regular Maintenance: Keep your system clean and efficient by scheduling annual maintenance.
Use Ceiling Fans: In the summer, ceiling fans can help circulate cool air, reducing the need to lower your thermostat. In the winter, reverse the fan direction to push warm air down.
Upgrade to Energy-Efficient Systems: If your HVAC system is old and inefficient, consider upgrading to an ENERGY STAR® rated unit.

10. Why is my HVAC system running but not cooling/heating my home?

If your HVAC system is running but not reaching the desired temperature, there are a few common causes:

Thermostat Issues: Check that your thermostat is set correctly and functioning properly.
Dirty Filters or Coils: Clogged filters or dirty coils can restrict airflow and reduce your system’s ability to heat or cool.
Refrigerant Leak: Low refrigerant levels in your AC or heat pump will prevent the system from cooling effectively.
Frozen Coils: Both air conditioning and heating units can develop frozen coils, especially if there’s low airflow or refrigerant issues.

In any of these cases, it’s best to call a professional to inspect and diagnose the problem.
