"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!"

Customers say: Quick response

"I was out of town when my air conditioner stopped working. My mother called 2 companies to check it out. The repair men were interested in selling us a new unit not fixing it. I found NT Electric & HVAC online through Home Advisor while I was out of town. The company had good reviews. I called Nathan and scheduled an appointment. He assessed the problem and fixed it! I would highly recommend Nathan and his company. He does what s best for the customer. His prices are fair and reasonable. I would use him again."

"Unfortunately, I needed an HVAC company to fix my AC during a heat wave. Most companies were 5+ days out before they could even diagnose our problem. Called 3 highly visible companies, from their marketing, who said they wouldn't even work on our unit. I went with a referral from a neighbor, mistake. This company took a week to get to us then the tech went MIA for 5 days with no contact when he said he would be back tomorrow with parts. Won't mention their name as there could have been multiple uncontrollable reasons why. I then did a lot of research on different companies across multiple review websites (including Angies) and Excel Air stood out. Once I spoke to the office staff, great experience, they had a tech out to our home in 2 days with our problem diagnosed. Our tech's name was Lucas who was efficient with his time, talked me through what was going on and gave us our estimate which we were happy to move forward with. Lucas fixed our problem in under 20 minutes. Me being me, I watched each step and saw the quality work. He even put in a fuse to ensure the same problem didn't happen again to our transformer. Once he fixed everything and got our new thermostat power, our AC has been working perfectly ever since. I'm now a really big supporter of Excel Air. Their office staff worked with our insurance company after hours and actually updated us (what company does this these days) the entire way. I can't tell you how impressed I was from their office, Lucas and most of all their successful resolution of our problems with our AC. Thank you Excel Air!"

"In all of my life, I’ve never met a company who completely overdeliveredwhat I contracted them for. Professional, seamless transaction. We needed a new HVAC system and we called George Ramirez and his team and George visited. They came out to assess the situation, gave us several options and prices, came when we asked, replaced the unit.George came out as a follow up and was able to repair our AC and saved us so much money. I could not be happier and relieved. The warranty to cover the unit was incredible and we feel so pleased that he will be here if we need him. I mean it sincerely, this is thecompany to call!! Thank you So Cal Boys!"

Heating and Air Conditioning questions, answered by experts

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

If left untreated, a frozen AC unit can lead to costly damage, especially to the compressor and evaporator coils. When ice forms on the evaporator coils, they become brittle and more susceptible to breaking. Plus, a freeze makes your AC system much less efficient, which means it's wasting energy and costing you more in your monthly energy bills.

While 72 degrees is a comfortable setting for many people, it’s likely not the most efficient temperature setting for your air conditioning unit. By pushing the temperature up to 75 or 78 degrees, you stand to save money on your energy bill. That said, these temperatures may be too warm to be comfortable for some people and are definitely too warm for most people to sleep comfortably.

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.

Trick question: There is no difference between an AC and a furnace blower motor. Whether you have central air and heat or just one of these, the same blower motor carries hot and cold air throughout the ductwork in your home. Certain systems may have separate blower motors for the AC and furnace, but each serves the same function.
