Just had a split system installed by Alan and his crew. I personally really care about the way the system is installed and that it looks good aesthetically. Alan’s crew were willing to move things based on my input and really kept me in the loop on decision making. It was a really good experience for me.Posted on Google![]()

The representative was on time, very professional and courteous. He explained the situation in easy to understand terms. He explained that I need a new furnace and he showed me photos of the furnace and the wear that has accumulated. I’m looking forward to working with them to finish the job. He got me a quote on the replacement unit and I’m satisfied.Posted on Google![]()

Lambert installed our A/C unit a couple of years back. They are really people we can trust. Great but honest price, good warranty, very reliable service. I won't go anywhere else. Manny is the most cordial, helpful and honest, sincere person you will be very happy to deal with. He goes the extra mile to help you to make sure you are satisfied. I guarantee it!Posted on Google![]()

Alan and his crew were top notch from the beginning of the project to the end. To begin the project Alan showed up, introduced his crew and did a walk through of the job. Before beginning he asked if we had any additional questions. The crew showed up on time each day, took a short lunch break and worked through the end of the day. There was never a question of when they would arrive or where they went. Prior to placing each component of the unit inside and outside of our home the Lead Tech, Daniel, checked in with us to be sure that placement was were we wanted it so there were no surprises at the end. Upon completion of the project Alan did a walk through, asked if we had any questions/concerns and showed us how to use the new unit. I strongly recommend Lambert Heating and Air Conditioning!Posted on Google![]()

I have been a client for over ten years and I have never been disappointed. First, the office staff is great; both friendly and efficient whether I am calling for annual maintenance or emergency repair. Manny the service technician is the best! When I greet Manny at the door I am confident the problem will be resolved at a fair price. Lambert Heating and Air is a family owned business and they are the only company I call.

Frequently Asked Questions About Cooling Services in Buena Park, CA
Lambert Heating & Air Conditioning provides residential cooling services, including air conditioning repair, AC installation and replacement, routine maintenance, system tune-ups, and troubleshooting for cooling and airflow problems.
Yes. We provide professional air conditioning repair for systems that are not cooling properly, will not turn on, are making unusual noises, have weak airflow, or are experiencing other performance issues.
Common signs include warm air coming from your vents, uneven temperatures throughout your home, weak airflow, frequent cycling, unusual sounds or odors, rising energy bills, or an AC system that will not turn on. If something does not seem right, having the system inspected can help identify the cause.
Replacement may be worth considering if your AC system is older, requires frequent repairs, struggles to keep your home comfortable, or has become increasingly inefficient. Our technicians can evaluate your current system and help you compare repair and replacement options.
Most residential air conditioning systems should receive professional maintenance about once a year, ideally before the hottest part of the cooling season. Regular maintenance can help improve efficiency, identify developing problems, and reduce the likelihood of unexpected breakdowns.
An air conditioner can run without cooling properly for several reasons, including a dirty air filter, thermostat problem, restricted airflow, refrigerant issue, frozen coil, electrical problem, or malfunctioning component. A professional diagnosis is the best way to determine the exact cause.
A properly maintained cooling system can operate more efficiently than one that has been neglected. Cleaning, inspecting, and adjusting system components can help your AC cool your home more effectively while reducing unnecessary energy use.
The right AC size depends on more than your home's square footage. Factors such as insulation, windows, ceiling height, layout, sun exposure, and the home's overall cooling load should be considered. An oversized or undersized system can reduce comfort and efficiency.
Yes. Lambert Heating & Air Conditioning installs and replaces residential air conditioning systems. We can help determine the appropriate system for your home based on its cooling requirements, your comfort goals, and energy-efficiency considerations.
Uneven cooling can result from airflow restrictions, ductwork issues, insulation differences, thermostat placement, system sizing, or other HVAC problems. We can inspect the system and determine what may be contributing to temperature differences throughout your home.
Regular professional maintenance, changing your air filter as recommended, keeping supply and return vents unobstructed, maintaining proper airflow around the outdoor unit, and addressing small problems before they become larger repairs can all help extend the life of your cooling system.
Yes. Lambert Heating & Air Conditioning provides professional cooling services for homeowners throughout and surrounding communities. Contact our team to schedule AC repair, maintenance, installation, or other cooling services.
