Comparative Summary

HVAC companies are always looking for ways to differentiate themselves from their competition, and those that have earned the prestigious Diamond Certified award are already several steps ahead. In addition to its Diamond Certified status, Perfect Star Heating and Air Conditioning sets itself apart by embracing challenging jobs that other companies aren’t qualified to handle. “We’re not afraid to step up to the plate and take on more difficult projects,” affirms owner Chris Donzelli. “A lot of our competitors will turn down jobs that seem overly complex, but we never shy away from a challenge.”

Perfect Star Heating and Air Conditioning has been providing HVAC services for residential clients in Alameda and Contra Costa Counties since 2015. The company has the training and equipment to maintain and repair all types of heating and air conditioning systems, and it’s also qualified to install whole house air purifiers, electrostatic filters, and other products that are designed to improve indoor air quality.

Unlike HVAC companies that focus all their efforts on maximizing their workload volume and sacrifice attention to detail as a result, Perfect Star Heating and Air Conditioning takes the time to ensure every job is done correctly. “It doesn’t matter how high-quality an HVAC unit is—if it’s not installed properly, it won’t perform as well as it should,” says Mr. Donzelli. “That’s why we take the time to perform the necessary calculations and make sure each unit is correctly sized and up to code.”

Another distinguishing attribute of Perfect Star Heating and Air Conditioning is its integration of digital technology in every aspect of its work. “We use a software program called Service Titan that allows us to send notifications to our clients,” explains Mr. Donzelli. “Whether it’s an appointment reminder or an update on their technician’s ETA, this technology makes it easy for us to communicate with our customers about their upcoming services, which they really appreciate.”

Industry Info

Due to the phase-out of Freon, if your air conditioning system was manufactured before 2010, you should plan for a replacement by 2020.

“Many homeowners aren’t aware that Freon, the refrigerant currently used to charge air conditioning systems, is being phased out and will stop being produced entirely by 2020,” says Chris Donzelli, owner of Perfect Star Heating and Air Conditioning in Concord. “The reason is simple: Freon, which is also known as R22 refrigerant, contributes to depletion of the ozone layer. The industry is switching to a new refrigerant called R410A, which doesn’t have the same negative environmental effects.”

While switching to a more eco-friendly refrigerant is a good long-term solution, it has some short-term consequences for homeowners with older air conditioning systems. “Since Freon won’t be produced after 2020, it’s going to be a lot more expensive to obtain, which will drive up the cost of repairing systems that run on it,” explains Mr. Donzelli. “Since virtually every air conditioning unit manufactured before 2010 runs on Freon, this will obviously affect a lot of homeowners.”

When asked if homeowners can simply use the new refrigerant to charge their old air conditioning systems, Mr. Donzelli says it’s unfortunately not that simple. “R410A isn’t compatible with Freon-based systems. The only way it would work is if you replaced the condenser unit and evaporator coil, at which point you might as well replace the entire thing. Using R410A in older air conditioning units has been found to cause premature system failure, and it’ll definitely void your warranty.”

While many people will be upset by the prospect of having to replace their HVAC systems, Mr. Donzelli points out some upsides to the situation. “By phasing out Freon, the government is basically forcing homeowners to replace their old HVAC systems with more eco-friendly, energy-efficient equipment,” he says. “Besides being better for the environment, these upgraded systems will allow homeowners to save money on their energy bills. Plus, with improved system performance, many will notice increased levels of comfort in their homes.”

Frequently Asked Questions

Q: How do you charge for your services?
A: We use straightforward pricing, which means you’ll know the final price of your job before we start working. That way, you don’t have to worry about any hidden fees.

Q: Do you clean air ducts?
A: No, because we believe it’s unnecessary. Ducts only get dirty if they have leaks or the air isn’t being properly filtered. In those cases, cleaning the ducts is basically putting a bandage on the real problem, which is why we prefer to focus on fixing the root cause of the issue.

Q: Do you offer a maintenance program?
A: Yes, we have our Star Membership Maintenance program. For a low monthly cost, we’ll come out to your home on a regular basis to check and maintain your HVAC equipment.

Q: Do you offer financing?
A: Yes, we offer several financing options, including HERO, Ygrene and Synchrony. We’re happy to explain the terms of each and help you choose the best option for your circumstances.

Chris Donzelli: HVAC Star

By James Florence, Diamond Certified Resource Reporter

CONCORD — Chris Donzelli was in between jobs when he decided to start from scratch and enter a new professional field. “It all started when I answered a newspaper ad placed by a local HVAC company,” he remembers. “I knew nothing about the field, but I was willing to learn, so they gave me a shot. During the next few years, I learned how to service and install residential heating and cooling equipment. Today, after 16 years in the industry, I own my own company. It just goes to show what you can accomplish when you put all your effort toward a goal.”

As owner of Perfect Star Heating and Air Conditioning, Chris says his favorite part of his job is developing his team. “I love teaching my employees and helping them hone their skills and knowledge in the industry. I’m very passionate about developing people—it’s extremely rewarding to see them grow and succeed.”

A resident of Brentwood (where he lives with his wife and two children), Chris expresses his appreciation for life in the Bay Area. “The weather isn’t harsh like in other parts of the country. Also, everything is close by—we’re just a couple of hours away from the snow, the beach and the wine country.”

Outside of work, Chris spends most of his free time having fun with his family. “We enjoy playing games together—pool, ping pong and chess are some of our favorites,” he details. “We’re also pretty outdoorsy and love to go camping and boating.”

In his life and career, Chris espouses the value of perseverance. “Get rid of powerless words like ‘can’t’—they won’t get you anywhere,” he advises. “Usually, when someone says they can’t do something, the truth is they just won’t do it. In reality, with plenty of effort and the right attitude, you can do anything you want.”

Ask Me Anything!

Q: What are your favorite sports teams?
A: The San Francisco 49ers, the San Francisco Giants and the Golden State Warriors.

Q: What kind of music do you like?
A: All kinds, from classic rock to country to hip-hop.

Q: What’s your favorite restaurant?
A: Melo’s Pizza & Pasta in Brentwood. However, if we’re going to splurge, it’s Ruth’s Chris Steak House in Walnut Creek.

Q: If you could travel anywhere in the world, where would you go?
A: Italy. I’m interested in the history, especially since my ancestors came from there.

Q: What’s your favorite snack?
A: Beef jerky.

  • The Importance of HVAC Unit Maintenance

    CONCORD — If you can’t remember the last time your heating and air conditioning system was professionally serviced, chances are it’s overdue for maintenance. Much like your car, your home’s HVAC system needs regular tune-ups to maintain optimal performance. You’d never dream of driving your car for years without a tune-up or at least an oil change, so why would you neglect the system responsible for heating and cooling your home?

    Even the newest furnace and air conditioning units need to be regularly serviced by a professional. Professional service maintains system efficiency, avoids unnecessary problems and prevents costly breakdowns, all of which can save a lot of money over the long term. So, if you’ve been putting off maintenance solely because of the cost, keep in mind that the consequences of neglecting your system can be far more costly.

    Complete Video Transcription:

    CONCORD — Host, Sarah Rutan: If you’re looking to maximize your home’s indoor air quality, look no further than Air Scrubber Plus. To learn more, we’re in Concord with Daniel Mendoza of Perfect Star Heating and Air Conditioning, speaking on behalf of Diamond Certified Expert Contributor Chris Donzelli.

    Daniel Mendoza: The Air Scrubber Plus product is great for every home. It turns your whole central heating and air system into a purifier for up to 3,000 square feet. It takes your $3.00 filters and makes them work 50 times better with its ActivePure technology. So, what you’re essentially doing is bringing the outdoor fresh air, which is great for you, into your house on those hot days where your house is closed up or on the cold days where your house is closed up. So, now you’re sanitizing, turning on the fan, still sanitizing your house. Cleans surfaces, kills bacteria, mold, viruses, and it’s been tested through independent studies by multiple universities.

    CONCORD — Host, Sarah Rutan: If you can’t remember the last time your HVAC system was inspected, it’s likely overdue for service. To learn more, we’re in Concord with Mike Jestadt of Perfect Star Heating and Air Conditioning, speaking on behalf of Diamond Certified Expert Contributor Chris Donzelli.

    Mike Jestadt: If you can’t remember the last time you had your heating and air conditioning unit serviced, chances are you’re long overdue. Much like your car, your heating and cooling system needs regular maintenance to stay running at peak efficiency. You’d never dream of driving your car for years without a tune-up or at least an oil change. So, why would you neglect the system that runs your home?

    The truth is that even the newest heating and cooling air conditioning units need regular tune-ups on a scheduled maintenance to prevent costly breakdowns, improve efficiency, and avoid unnecessary problems. Far from costing you money, a carefully thought-out and properly executed maintenance program can save you lots of money. So, there’s no need to put it off any longer. If you doubt the importance of your HVAC system’s right, just consider the dire consequences of neglecting that system.
