Why HVAC Systems Fail in Los Angeles

Los Angeles puts unique stress on HVAC systems. The San Fernando Valley sees triple-digit heat that strains compressors and capacitors. Coastal salt air corrodes outdoor coils. Older homes have aging ductwork and outdated electrical panels. Many systems are oversized or undersized for the space. Upright technicians understand these local factors and diagnose problems accordingly.

HVAC Repair vs. Replacement

Repair is usually the right choice for systems under 12 years old with minor to moderate issues. Replacement is more cost-effective if the system is over 15 years old, has a failed compressor or heat exchanger, or requires frequent expensive repairs. We always provide honest recommendations and written quotes for both options.

HVAC Brands We Service

We repair Carrier, Trane, Lennox, Rheem, Goodman, York, Bryant, American Standard, Amana, Ruud, Daikin, Mitsubishi, Fujitsu, LG, Panasonic, Bosch, and most other major brands. Our trucks are stocked with common parts for faster same-day repairs.

Common HVAC Parts We Replace

Our trucks carry common HVAC parts so we can complete most repairs in one visit. These include capacitors, contactors, fan motors, blower motors, transformers, ignitors, flame sensors, control boards, thermostats, and filters. For less common parts, we order quality replacements and return as soon as possible.

HVAC Maintenance Prevents Repairs

The most effective way to avoid HVAC repairs is regular maintenance. Upright’s tune-up includes cleaning coils, checking refrigerant, inspecting electrical connections, testing safety controls, and checking airflow. Maintenance also keeps manufacturer warranties valid and improves energy efficiency.

HVAC Repair Safety

HVAC systems involve high voltage, natural gas, refrigerant, and combustion. Upright technicians follow strict safety protocols, including checking gas connections, testing carbon monoxide levels, and ensuring proper venting. We never cut corners on safety, and we explain any safety concerns before completing work.

HVAC Repair Warranty and Financing

Every Upright repair is backed by a written labor warranty. If a repair fails under warranty, we return and fix it at no charge. For larger repairs or system replacements, we offer financing options to make the investment manageable.

24/7 Emergency HVAC Repair

HVAC emergencies do not wait for business hours. Upright offers 24/7 emergency repair from offices in Van Nuys, Sherman Oaks, and Woodland Hills. We answer calls live, dispatch the nearest technician, and complete most emergency repairs in a single visit.

HVAC Service Agreements and Maintenance

Joining Upright’s maintenance plan reduces the chance of unexpected repairs. Members receive scheduled tune-ups, priority scheduling, repair discounts, and documented service history. Regular maintenance also satisfies manufacturer warranty requirements.

When to Get a New System Quote

If your system is over 15 years old, needs major repairs, or cannot keep your home comfortable, a replacement may be more cost-effective. Upright provides free quotes for new systems, including Manual-J sizing, equipment options, and available rebates.

HVAC Energy Audit and Efficiency

During repair visits, Upright technicians look for opportunities to improve efficiency. This includes checking ductwork, insulation, filter condition, and thermostat programming. Small improvements can lower energy bills and extend system life.

Andrew Krakauer

Installed a new HVAC unit on my roof. The installation was quick and neat. The unit is working great. The was very reasonable. The owner Ernie was very nice and accomidating.

Annie Katz

I am so pleased with the work that Ernie did for me. Within 3 days of contacting him, a new mini split air conditioner was installed and repairs were made on the wall which needed to be opened in the installation all for a very fair price. His crew were prompt, clean and professional. I recommend Upright wholeheartedly.

Carlos Cuevas

Great customer service, great product knowledge, and explained the installation process well.

JD Nosrati

If you’re looking for an HVAC contractor you can actually trust, call Ernie at Upright Construction & HVAC. Ernie was incredibly generous with his time, patient with all of our questions, and kept his word throughout the entire project. He helped us choose the most efficient system for our home, clearly explained the pricing, handled the permits and paperwork, and Upright stuck to their quote with no surprises. His crew was professional, respectful, efficient, and treated our home with tremendous care. We hired Upright to remove our old HVAC system and install our new one, but after this experience, Ernie will be our first call for any future construction or contracting work. Honest, knowledgeable, dependable, and genuinely cares about his customers. I would recommend Upright Construction & HVAC to anyone. Thank you again, Ernie and team!

JILLIAN YEE-PHAM

So thankful for Ernest and his team to come out on a whim. Answer questions, provide knowledge, and did not try to upsell or spill BS, just a straight shooter. He got me the best deal at the best price. I am thankful that there is still nice quality people in the world!

Jo Anne

My AC broke on a Saturday night during a heat wave. Ernie fit me in that same night and fixed the problem. He was professional, pleasant, and reasonably priced. I'd recommend him and use him again.

Lacey Calhoun

If I could give Ernie 10 stars, I absolutely would!! I messaged him at 11pm on a Friday night after my A/C went out on me in this insane heat wave and he got back to me right away and then came out first thing the next morning on a Saturday. I genuinely thought I was going to perish in this heat until Monday but NOPE… by 9am, I was already up and running again and with air that was even colder than it was before it went out. As a single woman, I’m used to different contractors using that to underestimate me to upsell on things I don’t need but there was zero of that with Ernie. In fact, quite the opposite. Ernie worked to get just what needed fixing fixed and explained everything to me in a digestible way to help me get the most out of my A/C unit without having to come thousands of dollars out of pocket for a new unit. On top of that, he has the most genuine soul and is a family man so I felt safe and completely taken care of. His service is top notch and not the kind you get anymore these days. If you need any HVAC or construction work done, look no further. 10/10 recommend Ernie… he’s a gem!!

Jordan Levinson

Was able to come through and fix immediately on a super hot day! So thankful and so nice !

Katherine Takasago

Ernie communicated often while en route to our house. Once he got there, he assessed the situation and presented a reasonable solution that he was willing to do right now, even though it was getting late. He didn’t mind at all since it was cooler and our issue would be fixed. It was a wonderful experience! Very up front and honest, which was much appreciated.

Kelly Shapiro

I called Ernie due to our A/C leaking. He came out right away and was very friendly and pleasant. The issue ended up being a minor repair (a clogged P Trap that needed to be replaced). The cost was $375, but he knocked off $25. He was personable and helpful, and I am grateful that he was able to come out so quickly. We would definitely call Ernie again.
