1. Same Day Heating, Cooling, Plumbing
Website:https://samedaysd.com/
Address: 9771 Clairemont Mesa Blvd Suite E, San Diego, CA 92124
Contact: [email protected]; (619) 345-6504
Hours: Available 24/7
Same Day Heating, Cooling, Plumbing is immediately appealing if you’ve ever had your heat fail during winter. Their whole “Fixed in a Flash” approach is centered around fast response times and upfront pricing.
I actually had to call them myself last December when my heater stopped working overnight. What stood out was how clearly the technician explained the flat-rate cost before starting any repairs.
That upfront pricing model removes a lot of the stress that comes with worrying about hourly charges constantly increasing while the work is being done.
They also send NATE-certified technicians the same day you call, which adds a reassuring level of professionalism.
The downside is that they only cover the immediate local area, so larger property managers outside the county may need another provider.
And while they prioritize quick service, response times can still slow down during major winter cold snaps when demand spikes.

Jack was very pleasant and friendly. He arrived when he said he would. He got right to work. The furnace seems to be running fine now. He explained what he found and what he did to fix it in way I could understand. I am glad to give Jack a 5 Star recommendation.

2. Friar’s Plumbing Heating and AC Repair
Website:https://www.friarsair.com/furnace-repair-san-diego-ca/
Address: 5555 Magnatron Blvd Ste G, San Diego, CA 92111
Contact: (619) 317-1730
Hours: Available 24/7
Friar’s Plumbing Heating and AC Repair stands out to me mainly for how it handles emergency pricing, especially since they waive night and weekend surcharges.
That alone makes them feel more transparent than many providers that quietly stack fees during urgent calls.
We also like that they offer free second opinions on major system replacements. It’s a practical safeguard if you’re worried about being pushed into expensive upgrades you don’t actually need.
With over 35 years of local experience, they also seem pretty tuned in to the specific heating and plumbing issues homes face in the area.
The maintenance program looks useful for preventative care. A lot of the strongest perks, though, are tied to membership. This can feel limiting if you’re only a one-time customer.
And like many smaller operators, their same-day service can slow down during extreme weather when demand spikes suddenly.
Customer Reviews
Great service. Robert was very thorough and was able to determine the cause of the problem with the furnace and resolved the issue quickly. It was covered under the Friars 2 year maintenance plan for our HVAC system.

Roman and the team provided me with an honest and responsible assessment. Very professional with a very details assessment and options based on the circumstances and best for the house in the future. The replacement of the furnace and duct fixes were done in a timely manner with a great attention to details in the installation.
Very happy with my choice. Thank you for the help.

3. Anderson Plumbing, Heating & Air
Website:https://www.andersonplumbingheatingandair.com/
Address: 5183 Mercury Point, San Diego, CA 92111
Contact: (619) 320-1884
Hours: Available 24/7
Anderson Plumbing, Heating & Air is a pretty reliable choice if you value structure and consistency in a large service company.
Their “Nobody Wows Like We Do” guarantee and in-house training setup at Anderson Academy really set the tone for a more standardized, professionally managed experience.
They’ve also been operating since 1978, which usually translates into strong familiarity with older residential heating and plumbing systems.
A colleague of ours recently had them replace a faulty blower motor. What stood out in her experience was the technician’s clear communication and how clean the workspace was left afterward.
The trade-off, though, is scale. Because they run a large fleet, you’re unlikely to get the same technician every time. This can feel a bit impersonal if you prefer a more familiar, small-shop relationship.
Customer Reviews
Had some issues with my furnace, and from beginning to end dealing with Anderson has been some of the best customer service I’ve ever received. I would definitely recommend to family & friends and moving forward, i will be utilizing Anderson for all my heating, air, and plumbing needs.

4. Guthrie & Sons Heating, Air and Solar
Website:https://www.guthrieandsons.com/
Address: 8248 Ronson Rd, San Diego, CA 92111
Contact: (619) 815-5783
Hours: Monday-Sunday 12:00 AM-11:30 PM
Guthrie & Sons Heating, Air and Solar is a solid option for furnace repair when you need fast, dependable service.
They offer urgent dispatch availability, which is especially valuable when your furnace breaks down unexpectedly.
Their NATE-certified technicians bring strong technical training, helping ensure accurate diagnostics and effective repairs.
Their internal training program helps maintain consistent repair quality across technicians, and their low-pressure approach means you’re less likely to be upsold during urgent service calls
If a replacement is needed, their installation terms are quite reassuring. The 30-day “Remove and Refund” guarantee gives homeowners some breathing room.
Plus, the lifetime workmanship warranty adds longer-term confidence in the installation quality.
However, their smaller team can sometimes limit same-day availability during peak demand, and their service area restrictions may prevent some homeowners from accessing their furnace repair services at all.
Customer Reviews
Jonathon is a great technician. He is very willing to answer any questions and explains things very well. He is very transparent with letting us know cost, finance options, different furnace models and anything else we want to know. I would highly recommend him to anyone looking for furnace repair or replacement.

Wayne G. came by today to assess our malfunctioning furnace. He was patient and informative and went over all of our options from a minimum repair to a complete replacement. Most importantly, he was very low key and did not try to high pressure us into a decision. We will continue to deal with Guthrie – Thanks Wayne!

5. United Plumbing Heating Air & Electric
Website:https://localunitedservices.com/
Address: 6767 Nancy Ridge Dr Unit C, San Diego, CA 92121
Contact: (858) 215-6765
Hours: Available 24/7
United Plumbing Heating Air & Electric is a practical option when you need fast action during serious equipment failures, especially with their promised 60-minute emergency response time.
That kind of speed is one of the biggest advantages for stressed homeowners dealing with urgent heating or electrical issues.
What we also like is how broad their services are. Being a multi-trade hub means you can coordinate plumbing, HVAC, and even electrical work under one provider. This can make larger repair or renovation projects a lot simpler to manage.
Their flat-fee pricing before work starts also helps reduce uncertainty, since you know the cost upfront instead of watching it increase by the hour.
That said, their size is also a double-edged sword. Because they operate at a large scale, you may not always get a technician who specializes strictly in heating systems, which can matter for more complex furnace issues.
Customer Reviews
Luis R. Repaired my furnace and explain to me in detail how it worked .
Luis was very professional and respectful of the property.
If you want a good repair person for your furnace, ask for Luis !

I got service the same day I phoned in. I was concerned about fan noise in my furnace and Lance adjusted settings on the variable fan that solved the problem. I had 2 other companies look at it before and neither could get it done. I was only charged the minimum service call charge.
Highly recommend these guys.
