Top Questions From Home Owners
-
We recommend having your HVAC system professionally serviced 2x a year — once in the spring for cooling, and once in the fall for heating. This keeps things running smoothly and helps catch small issues before they become expensive repairs.
-
The size depends on your home's square footage, insulation, layout, and other factors. We offer free estimates to help you find the system that fits your space and budget.
-
If your system is over 10 years old, requires frequent repairs, or your energy bills are rising, it might be time to consider a replacement. We'll always give you an honest recommendation.
-
Clanking, banging, or whistling sounds can indicate loose parts, motor issues, or airflow problems. Give us a call to diagnose it before it turns into a bigger issue.
-
Uneven temperatures can be caused by poor ductwork, dirty filters, or incorrect system sizing. Our techs can help get things balanced again.
Efficiency & Cost
-
Regular maintenance, clean filters, and installing a smart thermostat are some of the easiest ways to improve efficiency. We can walk you through your options.
-
Absolutely. They help you save money by learning your habits and adjusting temperatures automatically. Plus, many can be controlled right from your phone.
-
If the repair cost is more than half the cost of a new unit — or if you're facing repeated breakdowns — a replacement may be more cost-effective in the long run.
-
Pricing varies by size, type, and features. Most systems fall between $5,000–$10,000 installed. We’re happy to provide a no-obligation estimate.
-
Yes — energy-efficient units can significantly cut down on utility bills over time. We’ll help you choose a model that fits both your needs and your budget.
-
Look for the SEER (Seasonal Energy Efficiency Ratio) rating. A higher SEER means better efficiency. If you're unsure, we can assess your system and make recommendations.
Air Quality & Comfort
-
Most homes benefit from a filter change every 1–3 months. Homes with pets, allergies, or heavy usage may need more frequent changes.
-
Yes! Properly functioning systems regulate humidity. If you're noticing dry air or too much moisture, we can help you find a solution.
-
Start with regular filter changes, duct cleaning, and humidity control. We also recommend UV lights and air purifiers depending on your needs.
-
Definitely. Your HVAC system plays a major role in maintaining balanced indoor humidity. We can also install standalone humidifiers or dehumidifiers for added control.
-
Yes, especially if it's been years since your last cleaning or if you've done renovations. Clean ducts reduce dust, allergens, and even improve system airflow.
