As summer approaches, homeowners across Massachusetts and Southern New Hampshire begin to rely on their air conditioning systems to keep their homes cool and comfortable. But before you set your thermostat to chill, one question can save you from mid-summer breakdowns and high utility bills:

Have you had your air conditioner professionally maintained this year?

In this article, we’ll explore:

• What an AC tune-up really includes
• Why preventative maintenance is essential
• How cheap “tune-up” ads are often misleading
• What a proper maintenace visit should include and how long it should take
• When to consider an upgrade instead
• The local pro’s approach to HVAC maintenance and system assessments

What Is an Air Conditioning Tune-Up?

An air conditioning tune-up is a critical part of maintaining the health and efficiency of your cooling system. It’s more than just a quick inspection—it’s a thorough preventative maintenance service that includes testing, cleaning, adjustments, and performance checks designed to catch minor issues before they become major problems.

A professionally completed tune-up helps your system:

• Run efficiently
• Last longer
• Avoid unexpected failures
• Maintain manufacturer warranties

Why HVAC Maintenance Is Essential

Regular maintenance offers real, measurable benefits for your cooling system—and your wallet.

Prevent Breakdowns: Small issues like low refrigerant or dirty coils can cause a full system failure if ignored. Tune-ups catch them early.

Lower Energy Bills: Dirty or miscalibrated systems use more energy. Seasonal maintenance restores efficiency and helps reduce your monthly costs.

Extend Equipment Lifespan: Well-maintained systems typically last years longer than neglected ones, saving you thousands in replacement costs.

Warranty Compliance: Many manufacturers require annual maintenance by a licensed pro to keep warranties valid.

Why Cheap “Tune-Up” Offers Can Be Misleading

You’ve probably seen the ads:

“$39 AC Tune-Up!” or “Free AC Inspection!”

Here’s the truth: many of these aren’t tune-ups at all—they’re sales calls disguised as service.

Watch for These Red Flags:

• Tech spends 15 minutes or less onsite
• No coil cleaning or refrigerant testing
• Pressure to sign up for expensive repairs or replacements
• “Inspection” only—no maintenance performed

These offers often exist to get a technician in the door. Once inside, the real goal is to sell you something—not to maintain your system. It is like bringing your car in for an oil change, but being provided nothing of actual value.

So, before booking an annual prevenative maintenance visit, be sure to ask what is included.

So, what should a proper A/C tune-up include?

When a Denommee Plumbing, HVAC & Electric technician performs a tune-up, we follow a structured, multi-point maintenance protocol that delivers real value, not just a look-over. These comprehensive system tune-up visits include the following.

Outdoor Condenser Maintenance:

• Clear debris from condenser unit
• Wash condenser coil
• Inspect fan motor and blades
• Test capacitor, contactor, and electrical components

Indoor Unit Maintenance:

• Inspect air handler or furnace blower
• Replace air filter (if needed)
• Check and clear condensate drain line
• Confirm secure electrical connections

Electrical & System Testing:

• Measure voltage, amperage, and system startup performance
• Check system refrigerant pressures and temperatures
• Measure cooling delta (return vs. supply air temps)
• Test thermostat response and accuracy

Our tune-ups are not designed to upsell. Instead, they're part of our commitment to safety, reliability, and honesty.

How Long Does a Tune-Up Take?

A proper air conditioning tune-up usually takes 60 to 90 minutes, depending on the age and condition of your system.

This gives our techs time to complete all cleaning, testing, and documentation carefully—without rushing through critical checks that could miss a problem in the making.

Does a New AC Still Need Maintenance?

Absolutely. Even brand-new systems require annual service. New systems are a big investement. You wouldn’t skip routine maintenance on a new car either and you shouldn’t skip looking after a new AC system.

In fact, skipping routine maintenance can void your equipment warranty, leaving you unprotected in the event of a future breakdown.

With regular tune-ups:

• You protect your investment
• You ensure maximum efficiency
• You keep your warranty intact

When to Consider an Upgrade Instead

During your maintenance visit, your Denommee technician may identify signs that your system is nearing the end of its service life. These can include:

• Poor cooling performance
• High electric bills
• Repeated repairs
• Compressor noise or failure

Pro tip: If repairs approach 50% of the cost of a new system, a replacement is often the more economical solution—especially with available Mass Save rebates for qualifying systems.
