Make Marx Your First Choice Read Some of Our Five Star Reviews

    "Every step was smooth and competently handled."

    We contracted Marx to replace our aging oil furnace with a high-efficiency heat pump. They arrived, promptly and prepared, on the agreed-upon installation date, protected walls and floors, worked diligently, and cleaned up afterward. Very professional!

    "Marx Mechanical staff are courteous and professional!"

    My furnace suddenly died and Marx Mechanical staff rearranged their schedule to be here the next day to replace my furnace (in a snowstorm). All my questions were answered and they even helped me set up the Daikin app on my phone.

    Marx Mechanical responded quickly when our furnace broke down on a cold day in December. They quoted a good price and installed the new equipment promptly. We were impressed with their professionalism and their promptness in dealing with the issue.

Frequently Asked Questions

How Long Does An AC Repair Typically Take?

The duration of an AC repair largely depends on the specific problem being addressed by the technician. Simple issues, such as replacing a capacitor or fixing a minor electrical fault, can often be completed in under two hours. More complex repairs, like repairing a refrigerant leak or replacing a compressor, may require several hours or potentially a follow-up visit if parts need to be ordered. The initial time is spent diagnosing the issue, after which the technician can provide a precise estimate for the repair. Always budget for the diagnostic time plus the necessary repair time.

Is It Better To Repair Or Replace My AC?

The decision to repair or replace your AC unit should be guided by its age and the cost of the necessary repair. If your air conditioner is over ten years old and the repair cost exceeds 50 percent of the price of a new unit, replacement is generally the most economical long-term choice. Newer, high-efficiency models provide significant savings on utility bills that can quickly offset the installation cost. However, for minor issues on a newer system, repair remains the practical and budget-friendly solution. A professional technician can help you evaluate your system's condition to make an informed decision. We also offer flexible financing solutions to ensure that you get the perfect air conditioning unit for your home.

Can I Fix AC Issues On My Own?

It is strongly advised that homeowners and business owners avoid attempting complex AC repairs unless they are certified HVAC technicians. Air conditioning units contain high-voltage electrical components and pressurized refrigerant, both of which pose serious safety hazards. Mishandling these systems can lead to severe injury, costly damage to the unit, or voiding your manufacturer's warranty. You can safely perform simple tasks like cleaning the area around the outdoor unit or replacing the air filter. For all technical repairs, diagnostics, and component replacements, you must contact a licensed professional.

How Often Should I Maintain My AC Unit?

For residential AC units, maintenance should ideally be performed once every year by a professional technician. This annual tune-up is best scheduled in the early spring before the peak cooling season begins. Regular maintenance ensures the system runs at maximum efficiency, which translates into lower energy bills and better cooling performance. Furthermore, annual service allows technicians to identify and fix minor issues before they escalate into major, expensive breakdowns. Consistent yearly maintenance is essential for preserving your AC unit's warranty and extending its operational lifespan. We offer comprehensive maintenance plans to ensure that your AC is in top shape year-round.
