AC Maintenance & Tune-Ups

Prevent Costly Repairs with Regular AC Maintenance

Your air conditioner works hard to keep your home cool, and like any mechanical system, it needs regular care to function efficiently. At Dor-Mar Heating, Air Conditioning, Plumbing, and Water Treatment, we provide comprehensive AC maintenance and tune-up services to keep your system running at peak performance, lower your energy bills, and extend the life of your unit.

Why Regular AC Maintenance is Essential

1. Improved Energy Efficiency

A well-maintained air conditioning system uses less energy, reducing your utility bills and helping you stay cool without breaking the bank.

2. Prevents Costly Breakdowns

Routine AC tune-ups catch small issues before they become major problems, preventing unexpected breakdowns during the hottest months.

3. Extends the Life of Your AC Unit

With proper maintenance, your air conditioner can last 15 years or more, helping you avoid the high cost of premature replacement.

4. Better Indoor Air Quality

A clean AC system filters out dust, pollen, and allergens, keeping the air in your home fresher and healthier.

5. Ensures Consistent Cooling

Regular inspections and adjustments help maintain even cooling throughout your home, eliminating hot spots and discomfort.

What’s Included in an AC Tune-Up?

At Dor-Mar HVAC, our air conditioning maintenance service includes a thorough 20+ point inspection and tune-up, ensuring your system is in top condition:

  • Check and replace air filters for improved airflow
  • Inspect and clean evaporator and condenser coils to increase efficiency
  • Test thermostat calibration for accurate temperature control
  • Lubricate moving parts to reduce wear and tear
  • Check refrigerant levels and top off if necessary

Professional Air Conditioning Installation & Replacement Services

If your air conditioner is outdated, inefficient, or frequently breaking down, it may be time to upgrade to a new air conditioning system. At Dor-Mar Heating, Air Conditioning, Plumbing, and Water Treatment, we provide expert AC installation and replacement services to keep your home cool and energy-efficient. Our certified technicians will help you choose the best new AC unit for your home and install it with precision.

Signs It’s Time for a New Air Conditioner

Not sure if you need a new AC unit? Here are some signs that it’s time for a replacement:

1. Your AC is Over 10-15 Years Old

Older air conditioning systems lose efficiency over time. If your AC unit is over a decade old, upgrading to a new air conditioning system can save you money on energy bills and improve cooling performance.

2. Frequent Breakdowns & Costly Repairs

If you find yourself constantly scheduling repairs, replacing your unit may be the more cost-effective solution. Investing in a new AC unit can eliminate the hassle of frequent breakdowns.

3. Rising Energy Bills

An outdated or inefficient AC system requires more energy to maintain comfortable temperatures. A new air conditioner with high SEER ratings can reduce energy consumption and lower your monthly bills.

4. Uneven Cooling & Hot Spots

Are some rooms in your home warmer than others? An aging system or improperly sized unit may struggle to distribute cool air evenly. A properly sized new air conditioning system will keep every room comfortable.

5. Loud Noises & Strange Smells

If your AC is making loud noises, rattling, or emitting burning odors, it’s a sign of failing components. A new AC unit will operate quietly and efficiently.

Choosing the Right New Air Conditioning System

Selecting the right new air conditioner for your home is essential for efficiency and comfort. Our experts will guide you through the selection process based on:

  • Home size & cooling needs – Ensuring the system is properly sized for your home.
  • Energy efficiency (SEER Rating) – Higher SEER-rated units provide better efficiency and cost savings.
  • Budget & financing options – We offer affordable solutions to fit your budget.
  • Smart thermostat compatibility – Upgrade your cooling system with modern controls.

Our Air Conditioning Installation Process

At Dor-Mar, we make installing a new air conditioning system hassle-free with our step-by-step approach:

1. In-Home Consultation

We assess your current cooling needs, home layout, and budget to recommend the best new AC unit for you.

2. Proper Sizing & Unit Selection

An incorrectly sized system can lead to inefficiency and premature wear. We ensure your new air conditioner is the perfect fit.

3. Professional Installation

Our licensed technicians install your new air conditioning system according to manufacturer guidelines, ensuring optimal performance and longevity.

4. System Testing & Optimization

We test the new AC unit, calibrate the thermostat, and check airflow to confirm proper operation.

5. Customer Education & Maintenance Tips

We walk you through how to operate your new air conditioner and offer maintenance tips to keep it running smoothly.

Benefits of Installing a New AC Unit

Upgrading to a new air conditioning system offers several benefits:

  • Lower Energy Bills – Modern AC units use less energy and operate more efficiently.
  • Improved Comfort – Even, consistent cooling throughout your home.
  • Quieter Operation – Enjoy a peaceful home with reduced noise levels.
  • Smart Technology Integration – Control your system with a programmable or smart thermostat.
