Q: Is a geothermal heat pump worth it?

• <div><p>Yes, geothermal heat pumps are worth the money. You can save about 70% on heating costs in the winter and around 50% on cooling costs in the summer with a geothermal heat pump compared to a traditional HVAC system. Over time, your savings on monthly utilities will pay for the cost of the geothermal heat pump installation. If you have an incredibly small yard, however, you may not have enough space for this type of system. </p></div>

Q: Can I stay in my home if there's a coolant leak?

• <div><p>While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.</p></div>

Q: Are there energy-efficient measures taken during these services?

• <div><p>Yes, including optimizing settings and suggesting upgrades if needed.</p></div>

Q: How often should I have my HVAC system serviced?

• <div><p>For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement. </p></div>
