Air Conditioning Questions
Why is my air conditioner blowing warm air?
This could be caused by a dirty filter, low refrigerant, or thermostat issues. Our AC repair technicians can identify the issue quickly.
How do I know it’s time to replace my air conditioner?
If your system is more than 10 years old, constantly needs repairs, or isn’t efficient, a new air conditioner installation might save you money long-term.
Do you install ductless mini-split systems?
Yes, we install ductless mini-splits, ideal for room additions, garages, or homes without ductwork.
How do I choose the right size AC for my home?
We calculate system size based on square footage, insulation, and layout to recommend the perfect AC system for your home.
Do smart thermostats help reduce cooling costs?
Yes, smart thermostats help lower energy bills by learning your habits and adjusting temps accordingly. We can install one during your next maintenance visit.
What’s the best temperature to set in summer?
78°F when you’re home, 85°F when you’re away is ideal. Use a smart thermostat for automatic scheduling.
Should I replace my AC and furnace together?
If both are aging, replacing them together ensures optimal efficiency. Ask us about bundled HVAC system upgrades for better performance.
Will a high-SEER unit lower my electric bill?
Yes. Upgrading to a 16+ SEER AC system can reduce energy costs by 20–30%.
What are signs I need AC repair?
Warm air, strange noises, short cycling, or high energy bills mean it’s time to call for AC service.
Do you offer free estimates on new AC installs?
Yes! We offer free quotes on all new air conditioner installations.
Heating System Questions
What’s the best time to schedule a heater tune-up?
Schedule your heater maintenance in the fall to prepare for cooler months.
Why is my furnace making a burning smell?
A dusty smell is common after inactivity. If it lasts more than 30 minutes, schedule a furnace inspection.
Do you install new heating systems?
Yes. We handle full heating system installations, including energy-efficient furnaces and heat pumps.
Can I just replace my furnace, not the AC?
Yes, but a matched system offers better efficiency. Let us help evaluate whether a full system replacement is best.
Are heat pumps good for Orange County homes?
Yes. Heat pumps provide efficient heating and cooling for our mild climate. We install heat pump systems tailored to your home.
What are signs I need heating repair?
Cold air, odd smells, or unusual noises could mean it’s time for furnace repair service.
How long do furnaces last?
Most furnaces last 15–20 years. Extend yours with regular maintenance.
Are gas furnaces better than electric?
Gas furnaces typically cost less to operate, but both options can be efficient. We’ll help you choose the right heating system for your home.
Can I finance a new furnace?
Yes. We offer furnace financing options to make your upgrade affordable.
