Frequently Asked Questions
How do you size a new system?

We perform a load calculation, check ductwork, and consider insulation and windows to recommend the right tonnage.

Can you help with financing?

We can discuss financing options and provide written estimates so you can compare choices.

How long does installation take?

Most replacements are completed the same day with thorough cleanup and system walkthrough.

Our written estimate covers equipment options, scope of work, warranty details, and any recommended duct or control upgrades.

Can you install high-efficiency systems?

Yes. We offer high-efficiency options and explain expected comfort and utility-bill impact for each equipment tier.

Do you evaluate ductwork during replacement?

Always. We inspect airflow and static pressure so your new system is not limited by undersized or leaky ducts.

If needed, yes. We can install and configure a compatible thermostat as part of the project.

What warranties come with a new HVAC system?

You get manufacturer equipment coverage plus our workmanship warranty. We review all terms at install completion.

Repairs vs. replacement: which one is right?

We always start with repair as the first option. When repairs are no longer sensible, we’ll recommend replacement and guide you through equipment choices and financing.

  • Age of the system. If your heater is near or past its expected lifespan, replacing can prevent cascading failures and lower operating costs.
  • Cost of repairs. When parts and labor are high relative to the value of the system, replacement may be the more economical choice.
  • Efficiency and features. A new system can cut bills, improve comfort, and add smart controls or better humidity management.

The quality of the installation determines how well your new system performs for its entire lifespan. We use high-quality materials, follow manufacturer specs, and commission every install so you’re not gambling with comfort or efficiency.
