"Nathan and Gordon at Total Home Environmental are lifesavers! I was facing estimates of $10,000 to $20,000 to replace my entire AC and heating system but instead they indicated that my 25 year-old AC compressor could be resuscitated by thoroughly cleaning the terminals and adding a hard-start kit. No other HVAC technician that came out gave me this option but they pulled it off for a fraction of the price of a new install!!! They are honest and knowledgeable professionals! Thank you so much!"

Highly recommend this company!"

"I highly recommend Trinity A/C & Heating. Our air conditioning system stopped working, so we called another company to diagnose the problem. After a brief inspection, including a trip to the attic, they told us we needed a completely new duct system at a cost of nearly $8,000. Fortunately, we decided to get a second opinion and called Trinity A/C & Heating. Jimmy thoroughly inspected the system and quickly identified the real issue: the system was simply low on refrigerant. They fixed the problem for a little over $300, and the A/C has been working perfectly ever since. Jimmy and Mike were honest, professional, knowledgeable, and took the time to explain everything clearly. Their integrity saved us thousands of dollars and prevented us from paying for unnecessary work. It's refreshing to find a company that puts honesty and customer service first. If you need A/C service, do yourself a favor and call Trinity A/C & Heating before making any major repair decisions. Thank you, Jimmy"

"GC Heating and Cooling put in a 3 zone furnace and AC system for our 3100 sq ft house in Manhattan Beach back in 2018. We recently had an issue due to the unprecedented heat wave and Gustavo and Jordan fixed the issue under short notice. You can always expect quality work and great service from them."

Air Conditioning questions, answered by experts

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.

There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

The compressor is the heart of your AC system and is one of the most important parts required to keep it functioning properly. If your AC unit is making a popping, banging, clanging, clicking, or screeching sound, it could point to a problem with the compressor. If the unit is physically vibrating, that can also be an indication that your AC compressor is going bad.

No, heat pump maintenance needs are very similar to air conditioners, including keeping outdoor units clean, changing filters regularly, and occasionally scheduling a refrigerant check to see if any has leaked out. Heat pumps typically switch automatically between heating and cooling, so you don’t need to worry about manually changing them every season. However, since they are always on call, they can develop wear and tear faster than an air conditioner.
