The Top Mid-Summer AC Services That Require Professional Help

by Feride Halma

What are the top summer-time AC services? If you're a first-time homeowner or new to central AC use, take a look at the most common reasons to call an HVAC contractor for air conditioning services during the warm weather months.

Refrigerant Retrofit

Does your AC system use HCFC-22 refrigerant? The United States no longer allows the production of this older refrigerant product. The environmentally unfriendly product is known to deplete the Earth's ozone layer. If your system still uses HCFC-22 (also known as R-22), it's possible a qualified contractor could retrofit the air conditioner.

According to the U.S. Environmental Protection Agency (EPA), only Section 608 certified HVAC contractors should repair or work on systems that use HCFC-22. This certification, combined with specialized experience and expertise, may provide the contractor with the technical and practical knowledge to retrofit your system.

If you're not sure why you should retrofit your system, consider the benefits. A refrigerant retrofit may increase energy efficiency and can decrease the environmental impact. Before you make the decision to retrofit your older AC system, discuss the options with the contractor. The professional may recommend a full replacement instead of a retrofit service.

AC Replacement

Why isn't a retrofit always an option? An older, worn, or seriously damaged system may cost more to repair and retrofit than to replace. Along with the repair costs, a retrofit may not dramatically increase the system's energy efficiency — at least, not in the way a replacement could.

While AC replacement is easier during the non-summer months (when you won't need to use the system), it's still a popular warm-weather service. If your system blows hot air, won't turn on, makes odd noises, has an off odor, or has another serious issue, schedule service as soon as possible. The HVAC technician can inspect the system and recommend a replacement that fits within your budget.

Refrigerant Line Repair

Why won't your air conditioner cool your home? While plenty of problems can cause loss of cooling, a refrigerant line leak is a major reason for this AC issue. Again, if your system uses HCFC-22, you'll need a Section 608 certified technician to repair a refrigerant leak. If it uses a newer refrigerant, you'll still need a qualified contractor to diagnose and fix the problem.

Thermostat Issues

It's possible the air conditioner itself isn't the problem. Thermostat failure is a common mid-summer issue that requires a service call. Even though you can buy a new thermostat in most improvement stores or online, you should consult a qualified professional to select and install the product.
