Will my ductwork need to be replaced during AC installation?

Not always. In many cases, existing ductwork can continue to function effectively if it is properly sized and in good condition. However, older or damaged duct systems may require modifications to ensure the new air conditioner performs efficiently. A professional evaluation helps determine whether adjustments are necessary to support proper airflow and system balance.

What type of warranty comes with a new air conditioner?

Most new air conditioning systems include a manufacturer’s warranty that covers major components for a specified period. Coverage terms vary depending on the brand and model selected. Proper installation and system registration are often required to maintain full warranty protection. Your installer can explain the coverage details associated with your specific equipment.

How Do I Know When My Air Conditioner Needs To Be Replaced?

Common signs that an air conditioner needs to be replaced include:

Frequent repairs
Weak airflow
Odd odors or sounds
High utility bills
Leaks
Uneven cooling

Most air conditioners have and estimated lifespan of between 15 to 20 years. There are, however, numerous external factors that can alter the projected life expectancy. While normal wear-and-tear and preventable damage can shorten the lifespan, routine maintenance and timely repairs from a trained professional can significantly increase it.

If you have recently noticed that your AC is not performing as it used to, this may be due to a repairable issue. However, in some cases, trouble with your air conditioner may indicate that your system is nearing the end of its useful life.

Frequently Asked Questions

AC installation typically refers to placing a new system in a home that has not previously had central air conditioning. AC replacement involves removing an existing unit and installing a new one in its place. Replacement projects may require adjustments to existing connections or components to ensure compatibility.

Before installation, homeowners should clear space around the indoor and outdoor units to ensure technicians can access them safely. Pets should be secured, and fragile items near work areas should be moved if possible. The installation team will handle the removal of the old equipment and protect the surrounding areas during the process.

Brad was great. Showed up early and gave me an honest assessment of the situation with my HVAC. I highly recommend MV Heating and Air for these two characteristics, because they tell me all I need to know about Brad and the company’s integrity: top notch It is a little over a year later, I decided to replace my 40- year old system. John came by and gave me the lowdown. He was very professional, explained everything from equipment available to needs for my specific situation. A week later, Brent and Leo showed up to install the new system. They were friendly, efficient, and walked me through all the new equipment and how it all worked. Again, I highly recommend Mission Viejo Heating and Air. Their customer service is outstanding

Mission Viejo Heating and Air installed both of my AC units about 1.5–2 years ago, so when I recently had an issue with the evaporator coil drain pan and a clogged primary drain line triggering the float safety switch, I called John right away. John came out with Martin, and these guys were absolutely amazing. They quickly diagnosed the problem, took care of everything, and made the whole process stress-free. Professional, knowledgeable, friendly, and just genuinely good people. It’s rare these days to find a company that stands behind their work and treats customers this well even years after installation, but Mission Viejo Heating and Air absolutely does. If you need a new AC unit, HVAC system, or service on your existing setup, I highly recommend these guys. Excellent service from start to finish.
