17 Best Air conditioning repair service in Denver for SameDay Service

Veteran Heating, Cooling, Plumbing & Electric is a veteran-owned home services company headquartered on Brighton Boulevard in Denver's River North Art District, covering heating, cooling, plumbing, and electrical work across the metro. It positions itself on transparent pricing: no trip fees and lifetime warranties on parts and labor. Its 24/7 emergency plumbing line covers nights, weekends, and holidays, and the company also helps Denver homeowners navigate Xcel Energy electrification rebates for high-efficiency HVAC upgrades. Reviews name technicians Darryl, Chris, and Jim Knight for knowledgeable, polite service: Darryl is credited with honest plumbing assessments and clear warnings about future repair needs, while Jim Knight is praised for persisting on two stubbornly backing-up sinks until the job was fully done. Customers describe same-day AC response during a heat wave, plain-language explanations, and an absence of upselling. A maintenance plan bundles annual AC, heating, and plumbing checks with waived service call fees, priority scheduling, and a repair discount. This is a fit for Denver-metro homeowners who want one veteran-owned contractor for the full home-systems stack with upfront pricing and no dispatch fees. The 24/7 emergency line addresses burst pipes and winter heating failures, while the rebate-navigation expertise may suit anyone weighing a heat pump or electrification upgrade. Additional listed locations in Greenwood Village, Englewood, and Littleton extend coverage south of the city.

Golden West Plumbing, Heating, Air Conditioning, and Electrical is a multi-trade contractor based in North Denver on Delaware Street, covering plumbing, heating, air conditioning, sewer and drain, and electrical across the Denver metro and surrounding cities. Plumbing coverage includes water heaters, drain cleaning, sewer service, sump pumps, bathtub and sink repairs, and gas and water piping; the HVAC side handles furnaces, air conditioners, boilers, and evaporative coolers; electrical work covers repairs, installations, and panels. Same-day service, upfront pricing, and 24/7 emergency availability are advertised, plus a VIP maintenance program for annual furnace, AC, and boiler care. Reviews name Jason Royster, Emma, Carlos Luna, Anthony, Max, Chris, Manny, Josh, and Riley. Positive themes include a furnace failure at 5 a.m. answered by a technician at 8:30 a.m. with a new furnace installed the next day, a boiler other companies said needed replacement fixed as a simple wiring issue, a Saturday gas leak handled calmly with a family in the house, and sump pump and swamp cooler work done neatly and on time. This is a fit for homeowners who want plumbing, HVAC, and electrical from one company with a maintenance plan to keep it all serviced. It suits buyers comparing major replacement quotes — the record shows technicians willing to repair where competitors recommended full replacement. For urgent calls, the pattern of same-day and next-day furnace and leak response is directly relevant.

Heart Heating, Cooling, Plumbing & Electric is a multi-trade contractor based in Denver's Sun Valley neighborhood on Bryant Street, covering heating, cooling, plumbing, and electrical for residential and commercial customers. Plumbing services include water heaters and valve work, sewer line replacement and camera inspections, drain repairs, sump pumps, and general plumbing; the HVAC side covers furnace and AC installation, repair, and maintenance; electrical work includes panels, EV charger installation, and troubleshooting. Free estimates, emergency services, and a lifetime warranty on parts and labor are advertised, plus a Heart Care Plan with discounted maintenance. Reviews name Trenton Barrance, David, Justin, Jon, Daniel, Victor Zubia, Josh Oliva, Jon Estes, Roberto, Wyatt, and Joel Ramirez. Positive themes include thorough furnace evaluations with honest repair-versus-replace advice, water heater installations done cleanly, drain repairs handled with budget sensitivity, and fast fit-ins for AC work. Counter-themes on record: one customer describes a sump pump installed incorrectly and an ownership change used as a reason not to honor prior work, and another describes a wasted scheduling day for a condo that the company ultimately said it does not service. This is a fit for homeowners wanting one company for HVAC, plumbing, and electrical with warranty backing on parts and labor. Furnace owners benefit from the pattern of detailed evaluations before replacement recommendations. Given the mixed warranty record, confirming how the lifetime warranty applies — and getting it in writing — is sensible before booking larger jobs.

Ultimate Heating, Cooling, Plumbing & Electric is a multi-trade contractor based in Denver's River North Art District on Broadway, covering heating, cooling, plumbing, and electrical. Its listed trades include air conditioning repair and installation, furnace repair, heating contracting, electrical installation, water heater and hot water system work, and plumbing. The company advertises same-day service, 24/7 availability, free estimates, warranties, and emergency services, with a high-volume, multi-crew operation. Reviews name technicians Kelly and Mike Bump. Positive themes include holiday AC repairs diagnosed and fixed the same day, accurate diagnoses where another company's visit had failed to find the problem, and professional system installations. One reviewer describes a negative turn after repeated service visits ended in a disputed outcome, illustrating that complex multi-visit jobs deserve documented scopes. This is a fit for Denver homeowners who want HVAC-led service with plumbing and electrical under the same roof, especially for air conditioning failures in peak summer. The free estimates and warranty coverage suit buyers comparing major system replacements. For emergency calls, the advertised round-the-clock availability and large crew roster make it a practical option to include in the shortlist.

Right Away Heating is a heating and cooling contractor in Denver on Santa Fe Drive near Maple Avenue, also covering plumbing calls. Its listed trades include furnace repair and installation, air conditioning repair and installation, boiler services, and plumbing repairs. Office hours run Monday through Friday, eight to five, with emergency service available around the clock by phone. Reviews name technicians Jose, Stefano, and Stepano. Recurring themes include a repair-first approach — Jose walked a customer through a furnace problem during zero-degree weather and gave the option of buying the parts to self-install rather than paying for full service — same-day air conditioning service for a downtown condo other companies declined to take on, and clear explanations of what technicians are doing and why. One reviewer reported a high repair quote and pressure to pay a service fee, an outlier against the positive majority. This is a fit for Denver homeowners who want a repair-before-replace philosophy on furnaces and AC units. The repair-first record makes it a good second opinion before committing to a replacement. For urgent heating failures in winter, the same-day and after-hours response pattern — Jose arriving within hours at zero degrees — is the relevant track record.

Absolute Plumbing, Electrical, Heating & Air is a multi-trade home services company in Denver's Montbello neighborhood that covers plumbing, electrical, HVAC, and generator work under one roof. Its plumbers handle repairs such as toilet fixes and leak resolution alongside broader residential plumbing needs, while its electricians take on panels, outlets, floodlights, and fixtures, and its HVAC technicians install and replace furnaces and AC systems. The company advertises same-day, round-the-clock emergency response, and a second listed office on Alameda Avenue extends its reach to Denver's west side. Its review record names technicians Ryan, Eddie, Gabriel, Ivan, and Anthony, along with a crew of Erin, Blake, and Daniel for a furnace-and-AC replacement described as professional work delivered on time with a clean finish. Customers credit the company with fair pricing and techs who explain the work in plain terms, particularly on toilet and HVAC jobs. A contrasting set of reviews faults slow phone communication and a confusing billing episode around a fixture installation, indicating that follow-through can be uneven from one visit to the next. This is a fit for homeowners who want a single call to cover mixed plumbing, electrical, and HVAC needs rather than coordinating three contractors. Montbello residents and nearby east Denver households get the closest coverage, while the Alameda office serves the west side. It may also suit anyone facing an urgent failure during a freeze, a scenario that appears repeatedly in reviews, though customers with time-sensitive work should confirm scheduling and pricing in advance.

Absolute Plumbing, Electrical, Heating & Air is a multi-trade home services company whose Alameda Avenue office serves Denver's west side with plumbing, electrical, HVAC, and generator work from a single provider. Its plumbers handle repairs such as toilet fixes and leak resolution, while its electricians take on panels, outlets, floodlights, and fixture installations, and its HVAC technicians install and replace furnaces and air conditioning systems. The west-side office complements a Montbello headquarters, with same-day and round-the-clock emergency positioning across the metro. The review record for the company names technicians Ryan, Eddie, Gabriel, Ivan, and Anthony, along with a crew of Erin, Blake, and Daniel for a furnace-and-AC replacement completed on time with a clean finish. Customers credit fair pricing and plain-language explanations, particularly on toilet and HVAC jobs, while a separate set of reviews faults slow phone communication and a billing dispute around one fixture installation. The pattern suggests solid on-site work paired with follow-through that can vary by visit. This is a fit for west Denver homeowners who want one call to cover mixed plumbing, electrical, and HVAC needs, from a chandelier swap to a full furnace replacement. The 24/7 emergency line addresses freeze-related failures that recur in local reviews, and the company's no-upsell pledge may appeal to anyone wary of oversold jobs. For time-sensitive work, confirming scheduling and pricing in advance is the prudent step.

The heating and cooling side covers furnaces, air conditioners, and heat pumps, and the electrical side handles panels, switches, outlets, and remodel wiring. Reviews name technicians Dan, Joseph, Zander, Bailey, Pedro, Chris, Brad, Meho, Kodiak, and Edgar. Recurring themes: same-day response for drain backups with camera inspections to show the problem, sewer line replacements completed in a single day, thorough option walkthroughs with no pressure, and help navigating insurance claims and energy rebates — including heat pump recommendations and Xcel rebate paperwork. One water heater review describes two failing units combined into a single high-recovery system with a mixing valve. This is a fit for Denver-area homeowners facing sewer line failure who want a contractor that both excavates and restores in-house. It also suits buyers comparing furnace, heat pump, and AC quotes where rebate guidance matters. For small business owners, reviewers note technicians working around operations and clients during service calls.

Its listed plumbing services include drain cleaning, water heaters, water mains, septic systems, sump pumps, sewers, garbage disposals, and appliance water lines; the electrical side covers panels, wiring, EV chargers, GFCI outlets, lighting, and generators; and the heating side covers furnaces, boilers, and duct cleaning. The company operates 6 AM to 10 PM, seven days a week, with no overtime charges stated. Reviews name technicians across all three trades — Tyler, Josh, Zach, Craig, Luke, Dave Newman, Jacob, Tony, and Jack — for thorough diagnosis, clear explanations of options, and professional, courteous conduct. Recurring themes include same-day resolution of furnace and water heater failures, patient troubleshooting, and technicians who show what they are doing so customers can handle future issues themselves. The consistent counter-theme is price: many customers describe the service as premium-priced, though most pair that with praise for reliability. This is a fit for homeowners who want one company covering plumbing, heating, and electrical work, especially combined jobs like water heater replacement with electrical upgrades. The long daily hours suit people who can only schedule around work. Budget-conscious customers should compare quotes, since the pricing sits at the premium end of the Denver market.

Prime Plumbing & Heating is a Denver plumbing and HVAC contractor based on Broadway, serving residential and commercial customers across the Denver metro with 24-hour availability. Its listed services include plumbing repairs and installation, drain cleaning, water heaters, furnaces, boilers, air conditioning, and sewer work. The company runs a high-volume operation with multiple technicians and advertises pricing quoted before work begins, with financing options for larger jobs. Reviews name technicians including Matthew, Mathew, Fernando, Gabriel, Keaton, and Trevor for on-time arrival, plain-language explanations, and repeat-customer trust. Recurring themes include accurate system checkouts, clearly set expectations, and customers who ask for the same technician by name. Some negative reviews describe poor communication on multi-department jobs, so customers booking combined plumbing and HVAC work should confirm the scope and timeline in writing. This is a fit for Denver-area homeowners and businesses wanting one company for both plumbing and HVAC — particularly furnace and water heater jobs that touch both trades. The 24-hour availability suits urgent calls. For multi-stage projects, getting the full schedule and supervisor contact upfront addresses the main negative pattern on record.
