They were so friendly and very thorough. They actually found a pretty big safety issue after we ordered a system and needed it installed. For us being a church safety is number one. They made a very low pressure recommendation for the issues. They were super professional and easy to deal with. I felt like they were consultants rather than contractors. It was a really amazing, not to sound trite.

From a professional standpoint, I liked the thoroughness they provided before installing. Also I love that they found a huge safety issue we had no clue was there.

Comparative Summary

Maintaining customer satisfaction is a crucial aspect of any business, but it’s even more important for HVAC contractors that have earned the prestigious Diamond Certified award. For Connolly Heating and Air Conditioning, the easiest ways to keep clients satisfied are to prioritize their needs and make sure they have positive experiences. “At the end of the day, we’re here to serve our clients, not make money,” says President Norman Grimes. “We routinely go out of our way to take care of our customers, address their needs, and make their homes safer and more energy-efficient.”

Connolly Heating and Air Conditioning has been cleaning air ducts, designing and installing HVAC systems, and providing other services that improve indoor air quality for residential and commercial clients in Contra Costa and Alameda Counties since 1992. The company also has the in-house capabilities to assess how customers are using energy beyond their HVAC systems and offer several energy-saving solutions, including photovoltaic solar systems.

Unlike less experienced HVAC contractors that are primarily concerned with finishing jobs as quickly as possible, Connolly Heating and Air Conditioning takes extra precautions to ensure its clients’ safety. “When we’re on a jobsite, we look for anything that could be a safety hazard,” explains Mr. Grimes. “For example, we inspect everything that’s gas-powered and make sure there are no carbon monoxide leaks. Also, if a customer is concerned about a sudden increase in their gas or electrical consumption, we’ll try to locate the source of the problem, which they really appreciate.”

Another distinguishing attribute of Connolly Heating and Air Conditioning is its proactive approach to quality control. “On every job, we assign a project manager to oversee the work and fill out checklists when the project is complete,” says Mr. Grimes. “We also follow up with each client after their job to make sure they’re completely satisfied and address any of their questions or concerns.”

Industry Info
Dirty ducts won’t just affect your home’s air quality—they may also affect your HVAC system’s energy efficiency.
“By having your air ducts regularly cleaned, you’re helping keep both your home’s air and your HVAC equipment clean, which is very important,” says Norman Grimes, president of Connolly Heating and Air Conditioning in Pacheco. “When dirt and dust are allowed to collect on the surfaces of heating and air conditioning equipment, it degrades its efficiency. You’d be surprised how much this can affect system performance—in some cases, energy efficiency can be reduced by as much as 50 percent.”

To ensure both clean indoor air and efficient HVAC system performance, Mr. Grimes recommends cleaning your air ducts every three to five years. If you notice your ducts need to be cleaned more frequently, it may indicate a problem with your system. “If dirt is accumulating in your ducts at a faster-than-normal rate, you may have some leaks,” affirms Mr. Grimes. “In addition to wasting energy, leaky ducts can bring in more dirt, which can then get into your HVAC system.”

However, Mr. Grimes says the problem may also be as simple as a dirty air filter. “The majority of these issues come down to a dirty filter, which is why it’s important to address every aspect of your HVAC system—not just the ducts. While the system consists of many parts, it functions as a whole, so it’s important to take a comprehensive approach.”

Frequently Asked Questions
Q: Do you provide emergency services?
A: “Yes, we respond to emergency calls on weekends and holidays.”
 
Q: How quickly can you be here?
A: “Typically, we’re able to arrive within 24 hours of every call.”
 
Q: My HVAC unit isn’t running. Does it need to be serviced?
A: “In this situation, we suggest calling us so we can try to solve the problem over the phone and save you the cost of an unnecessary service call. Try checking your breaker box to make sure the problem isn’t merely due to a partial loss of power. If that isn’t the problem, we’ll schedule an appointment to come out and perform a diagnosis.”
 
Q: Why is there a reduction in the air flowing from my HVAC unit?
A: “In many cases, this is caused by a dirty air filter, so the first thing you should do is check your filter and replace it if necessary. If this doesn’t solve the issue, we can look into other possible causes.”

DIAMOND CERTIFIED EXPERT CONTRIBUTOR ADVICE & TIPS FROM Norman Grimes

Expert CONTRIBUTOR PROFILE

Norman Grimes: Out of the Warehouse, Into the Field

By James Florence, Diamond Certified Resource Reporter

PACHECO — When Norman Grimes got a job shipping HVAC equipment, he never thought he’d one day be an HVAC service technician—or, for that matter, owner of an HVAC company. “As a young man, I worked for an HVAC supplier that shipped equipment all over the country,” he explains. “During my time there, I nurtured connections with a few of our clients and eventually started working for one of them. After 10 years of doing HVAC service and installation, I started my own business, which I’m still running today.”

Today, as owner of Connolly Heating and Air Conditioning, Norman says his favorite part of his job is interacting with customers. “When I worked in shipping, most of my interactions were with truck drivers, but since switching to HVAC service, I get to deal directly with homeowners, which I really enjoy. Often, customers are a bit distressed when they call us, so I like taking care of them, coming up with honest solutions and gaining their confidence.”

A resident of Martinez (where he lives with his wife, Amor), Norman expresses his appreciation for the unique character of Bay Area life. “I moved up here from Southern California, and it’s just a whole different vibe,” he says. “The people are a big part of it, but it’s also the weather. Down south, the climate is kind of monochromatic, whereas in the Bay Area, we get to experience the four seasons, which I like a lot.”

Outside of work, Norman stays busy with a variety of hobbies and pastimes. “I’m an avid golfer, bicyclist and soon-to-be pilot—I’ve almost finished getting my pilot’s license,” he says. “I also enjoy playing guitar, which is something I’ve been doing since I was 14. When we go camping, I always bring my guitar and sing songs around the campfire.”

In regard to a professional philosophy, Norman espouses the importance of honest, helpful service. “I’m all about being true to the customer,” he explains. “We professionals possess a world of knowledge, and it’s our responsibility to impart that to our customers and help them make informed decisions. That’s a big part of the culture I’ve created at Connolly Heating and Air Conditioning—a culture based on honesty and integrity.”

When asked the first thing he’d do if he were to retire tomorrow, Norman says he’d put more energy into the activities he currently enjoys. “I would probably compete in some golf tournaments and join a band. I’d also be more active in my church and invest some time into working with young people.”

Ask Me Anything!

Q: What’s your favorite local restaurant?
A: 88 Noodle House in Martinez.

Q: Who’s your favorite professional golfer?
A: I have two: Jordan Spieth and Dustin Johnson. They’ve been big inspirations for me personally.

Q: Are you an early bird or a night owl?
A: An early bird—I go the gym every morning before heading to work.

Q: Do you collect anything?
A: Guitars and other musical instruments.

Q: If you could immediately master any musical instrument, what would you choose?
A: The piano. I have a grand piano that I inherited from my grandmother and I’d really like to be able to play it.

  • Ductwork and Indoor Air Quality

    PACHECO — An often-overlooked factor for indoor air quality is the impact of ductwork. Since air ducts accumulate dirt and dust buildup over time, having them professionally cleaned is an important part of ongoing maintenance. On average, air ducts should be cleaned every two to five years. However, if your ductwork is damaged, routine cleanings won’t address the bigger underlying issue.

    Air ducts can sustain damage from a variety of sources, but one of the most common is rodents that claw or bite their way inside. When ductwork is damaged in this way, the resulting air leaks hamper HVAC system performance and compromise air quality by allowing dirt, allergens, and other particles to enter through the breaches. Worse still, if there are rodents living in the ductwork, traces of their excrement can end up in the air stream, which obviously poses a health hazard.

    To prevent these issues, damaged ductwork should be promptly repaired and sealed (or, if they’re in severe condition, replaced). Unfortunately, since air ducts are hidden behind walls and beneath the house, damage often goes unnoticed, as do the resulting problems. That’s why, to monitor the condition of your air ducts and avoid air quality issues, you should have them regularly inspected by an HVAC professional.

Expert video tip
  • Video: Consequences of HVAC System Neglect

    Complete Video Transcription:

    PACHECO — Host, Sarah Rutan: Even if your old HVAC system is still functional, if you haven’t maintained it, you could be headed for an adverse situation. Today we’re in Pacheco with Diamond Certified Expert Contributor Norman Grimes of Connolly Heating and Air Conditioning to learn more.

    Diamond Certified Expert Contributor, Norman Grimes: If you have an old furnace, and it’s 10-15 years old or that old soldier that’s 30-plus years old that you’re really proud of that it keeps rolling – a couple of things you need to consider. So, the people who may have lived in the home before you may not have taken care of the system. They may not have changed the filters. Do you do this?

    If not, then you probably have the typical scenario that we see, where people’s ductwork and their furnace will get dirty, and dirt on these surfaces, besides having an indoor air quality issue, it can also affect the efficiency of the equipment and cost you lots of money. Ultimately, if left alone, it will actually create mechanical failures in the system, and that can cost you money.

    So, it’s very important that you do consider this, because it can actually create mechanical problems down the road or even failures in the heat exchanger, which can put carbon monoxide into the home or even cause a fire. So, it’s very important that you at least change that filter every three months or call in a professional to take care of it.
