Air Conditioning Installation and Replacement

If your AC system is outdated or just isn’t performing as well as it used to, it could be the time to replace it. A lot of our customers are surprised when we calculate how much money they could be saving on their SDGE bill with a newer, energy efficient setup. Blue Diamond's San Diego air conditioning installation and replacement service can help you have a lower maintenance cost, higher energy efficiency, and an improved well-being.

Air Duct Repair & Installation

If your ductwork is old, damaged, or isn’t functioning properly, it can negatively affect your comfort and your energy bill. Call Blue Diamond for San Diego air duct repair and installation. Lack of proper sealing can cause up to 30% of your air to leak, which results in a less optimized system. At Blue Diamond, we provide efficient duct repair services across San Diego - and we also will install or replacement new ducts. Our ductwork repair technicians undergo extensive training to ensure we deliver reliable & efficient services.

Ductless Mini-Split Air Conditioner Installation

When it comes to ductless mini-split air conditioner installation in San Diego, there are 3 main pieces that we install so that you can control the individual temperature settings for up to four different rooms or sections.

  • The outdoor unit – similar to our normal AC, the outdoor unit does the majority of the cooling work and releases hot exhaust which helps drain the condensate.
  • The conduit – this contains a power cable, refrigerant tubing for on-demand cold, suction tubing, and a condensate drain. This needs only a small hole and connects to wall-mounted ductless mini AC units mounted in individual rooms in your home or commercial building.
  • The mini AC units – these units can support several different temperature zones, providing a different amount of cold air flow for each room where a unit is mounted.

Indoor Air Quality Solutions

How We Improve Your Air Quality

Since we spend the majority of our time indoors, it is important to pay attention to your San Diego home's indoor air quality. Apart from air pollutants, there are other factors that also affect air quality such as humidity control, ventilation, and HVAC system efficiency. Fortunately, Blue Diamond is your trusted indoor air quality advisor

Some of the proven IAQ solutions we offer include:
  • Air purification systems
  • Whole-house humidifiers
  • Duct cleaning
  • HVAC maintenance program

Furnace Repair

It's true that the heat in the San Diego area makes having a working air conditioner essential, but it’s important not to neglect your furnace either for those cold winter nights. That is why Blue Diamond offers high-quality furnace repair in San Diego. Our technicians provide services for furnaces and other heating systems designed to help your equipment function at peak efficiency. Our team is fully licensed and insured and our technicians are also clean, respectful, and known for going above and beyond to deliver 5-star service.

Furnace Installation & Replacement

Blue Diamond understands firsthand that committing to furnace replacement can feel like a major investment; however, there comes a point where it may be more cost-efficient to install a new unit than to keep repairing your old one. Make sure to think about what’s going to be more effective for your home in the long-term, and call Blue Diamond for energy efficient furnace installation and replacement in San Diego. The 3 most important factors to consider when deciding whether to install a new furnace are age of the system, the cost of the new system versus the cost of repairs, and energy efficiency for your monthly SDGE bill.

Things to Do in San Diego

San Diego, without a doubt, has something for everybody. San Diego is a perfect place to vacation, whether you want to watch a baseball game or spend the day at the beach. It can be difficult to fit everything into a single vacation because there is so much to do and see. Rather than trying to see anything, make sure to include these 7 San Diego landmarks on your itinerary for an unforgettable holiday.

1. San Diego Zoo and San Diego Zoo Safari Park

When visiting San Diego, you must visit the San Diego Zoo. It's a rite of passage to visit this legendary attraction, which is ranked as one of the best zoos in the world. The San Diego Zoo is home to over 3,700 rare and endangered species, ranging from monkeys swinging from branch to branch to towering giraffes and trumpeting elephants. Did you know the zoo is also a botanical garden with over 700,000 different plant species?

Follow our expert advice for the best San Diego Zoo experience:

  • Arrive as early as possible to secure a fantastic parking spot to see the animals in action. The majority of the animals rest in the afternoon.
  • Make use of the Bus Tour. The tour department departs every half hour and offers one of the most comprehensive zoo tours. It's an excellent way to see as many animals as possible in a single day.
  • Another must-see attraction is the San Diego Zoo Safari Park. The 1,800-acre park offers tourists a one-of-a-kind safari experience. You're guaranteed to have a wild time at San Diego Zoo Safari Park, between the behind-the-scenes tours and seeing animals in their natural habitats.
  • Reserve your tickets for the San Diego Zoo and San Diego Zoo Safari Park ahead of time using Reserve San Diego.
2. Cabrillo National Monument

The Cabrillo National Monument, like the other San Diego landmarks on our list, has its own story to tell. The historical monument honors Juan Rodriguez Cabrillo, who arrived in San Diego Bay in September 1542. When Juan Rodriguez Cabrillo discovered the field, he named it "San Miguel." It wasn't until 60 years later that explorer Sebastian Vizcaino called the place "San Diego."

You will discover the statue of Juan Rodriguez Cabrillo, hear about his journey, and look out into the ocean from the Old Point Loma lighthouse while visiting the monument.

3. USS Midway Museum

Climb aboard the USS Midway, an actual United States Navy aircraft carrier, for an educational experience you won't soon forget. The museum has something for all, with 60+ displays, self-guided tours, 29 restored aircrafts, and breathtaking ocean views.

The USS Midway, one of San Diego's most historic attractions, allows tourists to hear stories from Desert Storm pilots and experience life onboard the famous vessel. Daredevils can even "jet off" into the sky in a flight simulator!

By buying your USS Midway Museum tickets in advance, you can avoid long queues and spend more time inside the aircraft carrier.

4. Balboa Park

Did you know that Balboa Park is regarded as one of the best in the world? There are 15 museums, performing arts venues, botanical gardens, cultural and leisure attractions, and the San Diego Zoo in the park.

Balboa Park has over 1,200 acres to explore, so you might spend the majority of your San Diego vacation there and never get bored! As the nation's largest urban cultural park, it's easy to see why Balboa Park made our list of must-see San Diego attractions.

5. Torrey Pines State Natural Reserve

Hundreds of spectacular national and state parks can be found in California. Torrey Pines State Natural Reserve is one of 16 parks designated as reserves. This means that everything in the reserve is exactly as it was prior to the construction of the entire city of San Diego. From the tranquil paths to the breathtaking beaches, this natural reserve is one of San Diego's hidden gems.

Follow all of the rules established by the California State Park System while visiting Torrey Pines State Natural Reserve. The reserve's aim is to protect the park from waste and damage when tourists visit.

6. Gaslamp Quarter

The Gaslamp Quarter is San Diego's entertainment district, located in the center of the historic city. With 16.5 blocks of Victorian architecture and tales from San Diego's history, you have everything you need for a fantastic vacation right at your fingertips.

As a consequence, the following can be found in the well-known neighborhood:

  • Theaters, Art Galleries, and Award-Winning Restaurants
  • Bars and Live Music
  • Attractions and Museums
  • Shopping at its Best
  • Hotels and lodging of the highest caliber

We guarantee you'll enjoy Gaslamp Quarter, particularly since it's one of San Diego's most famous landmarks!

7. Old Town San Diego

Visit Historic Old Town San Diego, known as the birthplace of California. The State of California Department of Parks and Recreation founded Old Town in 1968, preserving the area's rich history. You can learn about San Diego's history, visit local shops, or attend a festival in the neighborhood.

It's no surprise that a neighborhood with so much tradition and fun made the list of top San Diego landmarks.
