What do you need to know about AC maintenance? If you're a first-time homeowner, take a look at the lesser-known (but important) reasons to hire a professional for AC repair and system maintenance.
The Refrigerant Requires Special Handling
Air conditioner refrigerant is a potentially harmful chemical that a homeowner should never handle on their own. Even though all types of refrigerants need professional attention, some also require a special certification to refill. According to the U.S. Environmental Protection Agency (EPA), Section 608 certification is a requirement to service HCFC 22–containing systems.
You May Not Know Which Air Filter to Use
An air filter may seem like a simple part of your AC system. Even though many models have a filter that slides in and out, the specific type you need for your air conditioner depends on several factors. From the size and material to the filter's ability to catch and stop microscopic particles, filter choice is tricky for the AC novice.
A routine AC system maintenance appointment is the perfect opportunity for a first-time homeowner to discuss filter options with a qualified HVAC technician. If you or a household member has allergies, asthma, a respiratory condition, or another healthcare need, ask the contractor what type of MERV (minimum efficiency reporting value) filter is right for your family.
Your Home's System May Require More Than a Repair
Does your home's AC system need a repair or a replacement? Before you google a DIY air conditioner repair video on YouTube, call a professional. Even though an online tutorial may make a repair seem simple, the real problem may include a complex set of issues. It's possible that the problem isn't easy to fix or that the system is too old/worn for a repair.
Only a qualified HVAC technician should repair a central air conditioning system. If you aren't sure whether your unit needs a repair or a replacement, an expert can help. The expert can inspect the system, diagnose the problem, and help you to better understand your options. If the recommended treatment includes a full replacement, you'll need a professional to install a new system.
Local Building Codes Require Professional Knowledge
What do local building codes have to do with your AC system? Whether you need a new air conditioner or want to make changes to an existing unit, everything in your home needs to meet local building codes. An HVAC professional should know local codes and how to ensure your air conditioner complies with them.
