"We hired Airmercia Air Conditioning & Heating to evaluate our heating system and propose repair solution. Ryan was very professional and punctual. He did not make any force sales. He just offered various repair and replacement solutions and explained pros and cons for each one. We decided to replace our furnace and duct system. Ryan did an excellent Job!! I highly recommend him for your HVAC project."

"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!"

"They were actually a second opinion for my non-working air conditioner but I went with them because they were very thorough and cheaper then the first company that looked at it. They replaced the same part as the first company quoted but were about $400 cheaper. They also managed to get the part in 2 business days where the other company said over a week. I didn't sacrifice cost for service though, they did a great job and now my AC works better than ever. I would definitely use them again. Another added bonus was that the repairman was a Air Force reservist and I am happy to support our troops and happy to support a company that also supports our troops.

"I was really impressed with the service provided by Nadav and he is team. I have a thirty year old home that still had the original HVAC systems. One located in the attic and the other underneath the house. Neither of these installations was simple. The Sky Clean Air team quoted me two days to remove and install new systems. The install crew was really professional, courteous and hard working. The underneath the house install was especially difficult with a tight crawl space in a less than hospital environment. These guys were not a show up at 10 leave at 3 pm crew.......they worked long hours both days to ensure they met the promised schedule.They kept me informed any issues throughout the installation process so there were no surprises. At the end of two days we had two beautifully installed systems that now cool our 4000 sq ft house in a matter of an hour instead of the 4 or 5 the old system required. I feel that the pricing they gave me was very fair and at the end of the job I felt like I got more value than what I paid. I would certainly use them again in the future."

"My ac, heater, and thermostat all went out at the same time. I called an hvac company and they said I needed a new furnace and ac and it'd be $12k. I called Heating and Air 365 to try to get a cheaper quote on a new system. Tommy came out and said the system was fine. It just had a short in the thermostat wires by the ac, my dog must have chewed through them. He replaced the wires and fixed something in the furnace and everything is working great. He saved me thousands. It's refreshing to see some honesty out there. He's got my business for life."

"At the beginning of the heatwave last week, I received a call from the family renting my condo in East County and they informed me that the AC stopped working. I tried a half dozen HVAC companies and none of them were available to provide service until the end of the week. I received a call from JMS West HVAC and they were available to provide service on that same day! Within two hours, the AC unit was repaired and my rental family was safe for the long hot week. The JMS repair crew was extremely professional and took care of business. Thank you!"

Heating and Air Conditioning questions, answered by experts

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.

Split systems are the most common type of HVAC system. Split systems have two main units: an indoor one and an outdoor one. These units work together to pull in air, heat or cool it, and distribute it throughout your home. Other popular types of HVAC systems include hybrid systems and packaged heating and air systems.

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

No, you should not run an air conditioner with a Freon leak. If you think your AC unit is leaking refrigerant, shut it off immediately. When you keep using a leaky air conditioner, it could damage the unit and release more refrigerant. After turning off the AC, have an HVAC pro come take a look at the unit.
