"Crew showed up on time. Job was completed in an hour. Afterwards my entire home was covered in a layer of sheetrock dust. One crew member wiped the dining table and kitchen countertop. I was shocked at the amount of dust. I spent the next 2 days vacuuming everything including the walls! The bedspreads and comforters will require a trip to the dry cleaner. Additional cost! And NO the price did not include a new air filter!"

"Angel was the first one to come out and ran the diagnostics on our old AC unit. With the use of a camera, he showed us the rust, decay and water damage inside. His knowledge was vast, and, if the pictures weren't enough, he was upfront and honest that we should replace the entire system before more damage was done. Also, compared to other HVAC specialists' quotes that we received none were better than MSP's. It felt great knowing that we got a great deal. Within a few days, a mighty team of two, Nate and Jose began replacing our ancient AC with a more powerful one that would cool our 2-story house from top to bottom. The guys were courteous, professional, and extremely hard working. Besides the excellent job of cleaning up, they also installed a new thermostat and took the time to show my wife and I how to use it. In the end, no one like's when their AC breaks down, especially during a hot California summer, but Angel, Nate and Jose saved the day. So to those 3 guys, thank you for keepin' us COOL!"

"Sam, who came out to give me an estimate for a new system, found out that the old fan motor was the culprit and recommended that we just repair the motor. He explained things in detail, helped us to save money in a genuinely sincere attitude, I was impressed how good his service was, and I recommend him for any HVAC issues. I will be using him in the future."

"Our AC unit stopped working on the hottest day of the year and Jake was extremely accommodating to fit us in the next day. David came out right on time, was super professional and was able to get our AC unit up and running fast! With our old dog and my pregnant wife dealing with the heat, these guys were really life savers! I would definitely recommend!"

Heating and Air Conditioning questions, answered by experts

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Yes, AC coil cleaning is definitely worth it. Cleaning your AC coils ensures your AC unit will function efficiently for the long term. Dirty and grimy AC coils make your unit work harder to cool your home, resulting in higher electric bills. Additionally, having your coils professionally cleaned regularly will reduce the possibility of extensive maintenance and repair costs.

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

Troubleshooting common issues with your AC often sheds light on a problem with the compressor. Signs that you need to replace a bad compressor include your AC blowing warm air, short cycling (turning on and off), making strange noises, and blowing less air overall. Since these problems can stem from several areas of your AC, always call a local AC repair team to confirm it's the compressor.
