Frequently Asked Questions About AC Installation
How long does AC installation take?
Most AC installations take between 4 to 8 hours, depending on the size and complexity of the system. Our crew arrives on time, works efficiently, and always keeps your home clean and disruption-free. We make sure your new system is installed perfectly before we call it a day.
What size air conditioner do you need?
The right size air conditioner depends on your home’s square footage, insulation, ceiling height, and layout. During your free consultation, our team will perform a precise load calculation to determine the best fit. This ensures maximum comfort and efficiency from day one.
Can you replace just the AC and not the furnace?
You can replace just your AC, but it’s not always the most efficient choice—especially if your furnace is aging, too. Mismatched systems can create inefficiencies and put added strain on your HVAC system. We’ll help you weigh the pros and cons to make the best decision for your home and budget.
Is a ductless mini-split a good option?
Yes! A ductless mini-split is a fantastic solution for zoned cooling, room additions, or older homes without existing ductwork. They’re sleek, efficient, and let you control the temperature in individual rooms—saving energy and boosting comfort.
Will a new system improve the air quality?
Absolutely. A properly installed system improves indoor air quality by filtering out dust, allergens, and pollutants more effectively—especially when paired with add-ons like a humidifier or purifier. You’ll breathe easier and feel more comfortable in every room.
What brands do you install?
We work with top-tier HVAC manufacturers known for durability, efficiency, and reliability. Our team will recommend the best brand and model based on your needs, budget, and home size—no pressure—just honest guidance and solid options.
Do you need regular maintenance after installation?
Yes, maintenance is key to protecting your investment and keeping your new HVAC system running at peak performance. Seasonal tune-ups, filter changes, and system checks help prevent breakdowns and extend the life of your equipment. Ask us about our hassle-free maintenance plans!
Can you install smart thermostats with a new system?
Definitely! We offer several smart thermostat options that integrate seamlessly with your new HVAC or air conditioning setup. You’ll be able to control your indoor comfort from your phone, optimize settings, and even track energy efficient usage habits.
