Metro Detroit AC Repair & Installation — Honest, Same-Day Cooling Service

When your air conditioning quits in July, you don't have time for a three-day wait or a contractor who talks you into a new system you don't need. We're Maximum Heating & Cooling — a family-run HVAC company serving Livonia, Dearborn, Westland, and communities across Metro Detroit — and we show up the same day with straight answers.

What Does Your AC Actually Need?

Not every cooling problem is a replacement. Not every repair is worth doing twice. Before we recommend anything, we diagnose what's actually wrong — then tell you honestly whether a repair, a tune-up, or a new system makes more sense for your home and your budget. We've been doing this for 14 years, and we'd rather earn your trust than your invoice.

Our air conditioning services cover every situation:

Warm air, strange noises, a unit that won't start — we diagnose and repair central air conditioning systems the same day across Metro Detroit. No upsell pressure. If it can be fixed, we'll fix it.

AC Repair

If your system is beyond repair or simply too old to run efficiently, we size and install new central air systems correctly the first time. Proper load calculation, Coleman factory-certified installation, and honest guidance on SEER2 ratings so you know exactly what you're buying.

A pre-season tune-up catches refrigerant issues, dirty coils, and failing components before they strand you in a heat wave. We check everything, clean what needs cleaning, and tell you what we find — good or bad.

AC Tune-Up

If you live in an older home in Livonia, Dearborn, or Redford and you're running a hot-water or steam boiler, you already know how hard it is to find a contractor who actually knows this equipment. We do. We install, repair, and maintain residential boilers — and we're one of the few companies in Metro Detroit that still takes this work seriously.

How We Handle Repair vs. Replacement

A lot of homeowners come to us expecting to be told they need a new system. Sometimes that's true — but not as often as the industry would have you believe. Here's how we think about it:


  • If your system is under 10–12 years old and the repair cost is reasonable relative to its remaining life, we recommend the repair.


  • If your system is aging, inefficient, and failing repeatedly, we'll tell you that honestly — and show you the math on a new unit versus continued repairs.


  • We never recommend replacement to hit a sales number. We recommend it when it genuinely makes sense for your home.


You'll always know what we found, what it costs to fix, and what your options are before any work begins.

Cool Your Home Without Breaking the Budget

New central air doesn't have to mean a painful bill. We offer flexible financing through Optimus and Klarna — with approvals available for credit scores as low as 540 and 18-month deferred interest options. And if you're upgrading to a higher-efficiency system, DTE Energy currently offers AC rebates between $100 and $300 depending on the SEER2 rating of the equipment installed.


We'll help you understand which rebate tier your new system qualifies for and walk you through the financing options that fit your situation.

Protect Your AC Before It Fails

Our twice-yearly maintenance plan covers a full AC tune-up every spring and a heating inspection every fall. Plan members get priority scheduling, 10% off parts and labor, and a free diagnostic with any covered repair. It's the most cost-effective way to keep your cooling system running reliably through every Metro Detroit summer.

Frequently Asked Questions About AC Service in Metro Detroit

  • How quickly can you respond to an AC breakdown in summer?

    We prioritize same-day service for air conditioning emergencies throughout Metro Detroit. Call us directly and we'll tell you exactly when we can be there — no vague four-hour windows.

  • How do I know if my AC needs a repair or a full replacement?

    Age, repair history, and efficiency are the three factors we look at together. A system under 12 years old with a single repair issue is usually worth fixing. A system that's failing repeatedly or running at low efficiency is often cheaper to replace over a three-to-five year horizon. We'll give you the honest breakdown either way.


  • Who installs central air in Livonia and the surrounding Metro Detroit area?

    We do. Maximum Heating & Cooling installs central air conditioning systems throughout Livonia, Dearborn, Westland, Canton Township, and the broader Metro Detroit area. We're Coleman factory-certified and have been doing this work for over 14 years.


  • What SEER2 rating should I look for in a new AC system?

    The federal minimum for Metro Detroit is 14.3 SEER2. Higher-efficiency systems (16 SEER2 and above) qualify for DTE rebates and reduce your monthly energy costs. We'll walk you through the tradeoff between upfront cost and long-term savings so you can make the right call for your home.


  • Does my refrigerant type affect my repair or replacement decision?

    It can. Older systems using R-22 refrigerant are increasingly expensive to service because R-22 has been phased out of production. If your system runs on R-22 and develops a refrigerant leak, replacement often makes more financial sense than recharging. We'll tell you exactly what refrigerant your system uses and what that means for your options.


  • Do you offer financing for a new AC installation?

    Yes. We work with Optimus and Klarna to offer flexible payment options, including 18-month deferred interest plans. Financing is available for credit scores as low as approximately 540. Apply online or ask us when we're on-site.
