    Hotel tiers

    A range of accommodation options near the venue and across key areas.

    Marriott Marquis San Diego Marina (conference venue hotel)

    Downtown waterfront, San DiegoOn site - the conference hotel to venue

    The conference hotel and venue. Staying here means no daily commute, direct access to sessions, receptions and exhibitor space, and the easiest option for attendees with back-to-back meetings.

    Downtown waterfront and Marina District hotels

    Embarcadero and Marina District, a short walk from the venueApprox. 5-15 min on foot to venue

    Full-service and upscale downtown properties clustered around the harbour, within walking distance of the Marriott Marquis. Convenient for evening harbourfront receptions.

    Gaslamp Quarter and core downtown hotels

    Gaslamp Quarter / Broadway corridor, San DiegoApprox. 10-20 min on foot or a short rideshare to venue

    Midscale and limited-service options with dense restaurant and evening activity nearby. Good value for attendees who do not need to be inside the conference hotel.

    Airport corridor and Harbour Island hotels

    Harbour Island, Shelter Island and the SAN airport corridorShort rideshare or bus ride to downtown to venue

    Lower-cost alternatives for budget-conscious attendees. Budget an additional daily transfer cost and time when comparing nightly rates against downtown properties.

    Local transport

    Get around the city with these convenient transport options.

    rideshare

    Estimated costUSD 35-75 taxi or rideshare to the venue district
    Best forSan Diego International (SAN) to Marriott Marquis San Diego Marina

    Rideshare pickup at SAN is signposted from the terminals. Journey time is short in normal traffic, so this is usually the simplest door-to-door option with luggage.

    bus

    Estimated costUSD 35-75 taxi or rideshare to the venue district
    Best forMTS Route 992 (airport to downtown San Diego)

    Metropolitan Transit System Route 992 connects San Diego International Airport with downtown San Diego, including stops near the waterfront and Santa Fe Depot. Useful for attendees travelling light.

    light rail / trolley

    Estimated costUSD 35-75 taxi or rideshare to the venue district
    Best forSan Diego Trolley (Green, Blue and Orange lines) via downtown stations

    The trolley network reaches downtown stations close to the harbour and Gaslamp Quarter. Handy for moving between a downtown hotel and the venue, or for exploring San Diego in the evening.

    commuter rail

    Estimated costUSD 35-75 taxi or rideshare to the venue district
    Best forCOASTER rail from North County coastal communities to Santa Fe Depot, downtown San Diego

    An option for attendees staying north of the city in coastal communities such as Carlsbad or Oceanside. Santa Fe Depot is a short walk or rideshare from the venue district.

    taxi

    Estimated costUSD 35-75 taxi or rideshare to the venue district
    Best forDowntown San Diego hotel to the Marriott Marquis San Diego Marina

    For short downtown hops a taxi or rideshare is quick, though walking is often faster between waterfront and Gaslamp Quarter properties.

    Weather

    San Diego has a mild coastal climate in December, the month of the HARDI Annual Conference. Daytime temperatures typically sit around 18-21 C (65-70 F) with overnight lows near 10-13 C (50-55 F). December is one of the wetter months of the San Diego year, but rain arrives mostly as short Pacific storm systems rather than sustained rain, and mornings can start with a coastal marine layer. Conditions are comfortable for walking between the waterfront venue, downtown hotels and the Gaslamp Quarter. This is a typical seasonal pattern, not a forecast - check the live forecast a few days before departure.

    Plan for the climate

    Check temperatures and pack accordingly

    Venue connectivity

    San Diego runs on US mobile networks (Verizon, AT&T and T-Mobile), and coverage downtown and around the harbour is strong. Visitors from outside the United States typically need a roaming plan that covers the US or a US eSIM for data, since domestic roaming can be expensive. Hotel and conference Wi-Fi is normally available to registered attendees; confirm the network name and access code at the registration desk when you collect your badge. US venues use 120 V / 60 Hz power with Type A and Type B plugs, so bring a plug adapter and check whether your devices are dual voltage before relying on them.

    Ride-hailing

    Taxis

    Public transit

    Car rentals

    Cultural notes

    Useful information to help you have a smooth and respectful visit.

    Business dress

    Business casual is typical for distributor conference sessions and manufacturer meetings, with business or smart attire for evening receptions. San Diego is a coastal city, so light layers work better than heavy formal clothing.

    Tipping and paying

    Tipping is customary in the United States: around 15-20 percent on restaurant bills, and a small amount for bar service and hotel housekeeping. Credit cards are accepted almost everywhere, and prices are usually quoted before local sales tax and tips.

    Time zone and scheduling

    San Diego runs on Pacific Time, three hours behind the US East Coast and eight hours behind Central European Time outside daylight-saving changes. Build in a day to adjust if you are arriving from Europe or Asia, and confirm the conference start time in Pacific Time.

    Arrival and badge collection

    Arrive early on the first day to collect your badge at the Marriott Marquis San Diego Marina and to pick up the current programme. Waterfront evenings in December are cool, so keep a light jacket with you during the day.

    Downtown San Diego

    The venue sits on the downtown waterfront next to the Gaslamp Quarter, a compact district of restaurants and bars that is easy to walk in the evening. The San Diego Trolley and the COASTER commuter rail connect downtown with the wider county.

    Language and meetings

    Business is conducted in English. Distributor buying decisions are relationship-driven and often made in scheduled meetings or at manufacturer hospitality events, so confirming times in advance works better than relying on walk-up conversations.

    Practical guides

    Visitor & Exhibitor Essentials

    Everything needed to arrive prepared, navigate the event, and make the visit productive.

    Flights

    Destination: SAN

    Book into San Diego International (SAN) where possible; it is roughly 3 miles from the downtown waterfront venue, so transfers are short and inexpensive. Direct international service to SAN is limited, and many overseas attendees connect through Los Angeles, San Francisco, Dallas, Atlanta or Chicago before the final leg; allow a comfortable connection buffer because US immigration is cleared at the first point of entry. December is a peak holiday travel month in the United States, and the conference itself creates extra demand on flights and downtown hotel rooms, so booking early usually pays. Confirm the exact 2026 conference dates at hardinet.org before locking non-refundable tickets. Travellers from abroad should verify ESTA or B-1 visa status before booking.

    Transport

    Get to the venue and around the city with these options.

    Airport → venue: Primary gateways: San Diego International (SAN). Allow road or rail time to Marriott Marquis San Diego Marina; on-site parking is usually available at major exhibition venues.

    Hotel → venue: Precinct hotels near Marriott Marquis San Diego Marina: Downtown waterfront, San Diego: Marriott Marquis San Diego Marina (conference venue hotel); Embarcadero and Marina District, a short walk from the venue: Downtown waterfront and Marina District hotels; Gaslamp Quarter / Broadway corridor, San Diego: Gaslamp Quarter and core downtown hotels.

    Ride-hail: Rideshare services (Uber and Lyft) operate throughout San Diego, including dedicated pickup zones at San Diego International Airport and drop-off at the Marriott Marquis San Diego Marina and other downtown hotels. A short downtown trip typically runs around USD 8-15 and the airport transfer around USD 25-45, with surge pricing possible around conference sessions and in the December holiday period. Confirm live fares and pickup points in the app before you order.

    Public transit: San Diego's Metropolitan Transit System (MTS) operates buses and the San Diego Trolley, with downtown stations near the waterfront and the Gaslamp Quarter. Route 992 links San Diego International Airport with downtown, and the COASTER commuter rail connects coastal North County communities to Santa Fe Depot downtown. A single journey is approximately USD 2.50 on MTS services (confirm live fares, day passes and route changes with MTS before travel).

    Parking: The Marriott Marquis San Diego Marina has on-site parking, and downtown San Diego hotels typically offer valet or self-parking for a daily fee. Downtown street parking is metered and limited, and convention-period demand pushes garage rates up, so pre-book parking with your hotel if you are driving. Confirm current daily rates and in-and-out privileges directly with the hotel or venue before you arrive.

    Weather

    Plan and pack for the event climate.

    Month: December 2026 (Northern Hemisphere winter, Pacific coastal Southern California)

    Temperature: Typical December range: daytime highs around 18-21 C (65-70 F) and overnight lows around 10-13 C (50-55 F). Coastal areas stay cooler and damper in the morning. Treat these as seasonal norms and check the live forecast before departure.

    Seasonality: December falls in San Diego's cooler, wetter half of the year, with occasional Pacific storm systems bringing short spells of rain and a morning marine layer along the coast. Most days remain dry and mild, which suits walking between the waterfront venue, downtown hotels and the Gaslamp Quarter.

    Packing: Pack light layers for daytime temperatures around 18-21 C (65-70 F) and a jacket or sweater for cool waterfront evenings (10-13 C / 50-55 F). Add a compact umbrella for possible December rain showers, comfortable walking shoes for downtown and the Embarcadero, business casual clothing for sessions and receptions, and a plug adapter plus any dual-voltage checks you need for US 120 V power.

    T-7

    About 7 days out: download the HARDI conference app or save the schedule page so you can adjust your plan when session times are confirmed.

    T-8

    About 7 days out: set up roaming or a US eSIM if you are visiting from abroad, and confirm that your phone supports the US 120 V charging setup or bring an adapter.

    T-9

    About 5 days out: pack business casual clothing, a jacket for waterfront evenings, a compact umbrella and comfortable walking shoes for downtown San Diego.

    T-10

    About 3 days out: check the live San Diego forecast. December daytime temperatures are typically around 18-21 C (65-70 F) with overnight lows near 10-13 C (50-55 F), and short rain systems are possible.

    T-11

    About 2 days out: confirm your ground transfer plan from SAN - rideshare, taxi or the MTS Route 992 downtown bus - and note the return pickup point at the hotel.

    T-12

    About 2 days out: collect your distributor branch data and any supplier questions you want answered, so you can compare programs and terms with peers at the conference.

    T-13

    Day before: complete online check-in, confirm your badge pick-up location at the Marriott Marquis San Diego Marina, and arrive early enough to settle in before the opening session.

    T-14

    Glossary

    1
    HVACR
    Heating, Ventilation, Air-conditioning and Refrigeration - the equipment and service sector served by the wholesale distributors attending this conference. Distributors stock everything from furnaces and condensing units to refrigerant, controls and service tools for contractor customers.
    2
    Wholesale distributor (branch)
    A company that buys HVACR equipment and parts from manufacturers and resells them to licensed contractors, dealers and institutional accounts through a network of local branches and counter sales desks. Distributor economics - margin, turns, fill rate - are the core business content of the HARDI Annual Conference.
    3
    Line set
    The matched tubing, fittings and insulation bundle used to connect a split-system outdoor condensing unit to an indoor coil or air handler. Line sets and related installation consumables are typical distributor counter stock.
    4
    A2L refrigerant
    A class of lower-flammability refrigerants (ASHRAE safety group A2L) adopted in new residential and commercial cooling equipment as hydrofluorocarbon (HFC) use is phased down. Distributors must plan cylinder handling, storage, training and code compliance for A2L product lines.
    5
    AIM Act
    The American Innovation and Manufacturing Act, the US law behind the scheduled phasedown of HFC refrigerants. It drives the refrigerant transition that HVACR distributors, contractors and manufacturers are adapting to through equipment changes, recovery and reclamation.
    6
    SEER2 / efficiency standards
    The US seasonal energy efficiency ratio metrics used for residential cooling equipment ratings, updated with more representative test conditions. Distributor purchasing and inventory plans follow each regional efficiency step-up because unsold low-efficiency stock cannot be sold after a standard changes.
    7
    IAQ (indoor air quality)
    Filtration, ventilation, humidification, dehumidification and purification products sold to improve building air. IAQ has become a standalone distributor category alongside traditional heating and cooling equipment.
    8
    Hydronics
    Water-based heating systems - boilers, circulator pumps, expansion tanks, radiant panels, valves and piping. Hydronic components are a staple branch category in colder US markets and appear in the product scope of HVACR distributor shows.
    9
    OEM vs aftermarket parts
    OEM parts are manufacturer-branded components for new equipment or warranty repair; aftermarket parts are equivalent components sold for out-of-warranty service. Distributors typically carry both, and the mix drives margin and inventory decisions.
    10
    Counter day / dealer counter sales
    A branch-level sales event where contractors come to a distributor location for product demonstrations, training and promotional pricing. Counter days are a key demand-generation tactic for HVACR distributors attending the annual conference.
    11
    Buying group / cooperative
    An organisation of independent distributors that negotiates collective purchasing terms with manufacturers. Buyers from buying groups and cooperatives are part of the distributor audience at HARDI events.
    12
    Refrigerant recovery and reclamation
    The capture of used refrigerant from equipment for recycling to specification or destruction. Regulatory phasedown has turned recovery and reclamation into a compliance service distributors and contractors must support.
