"Short: Had them replace my upstairs full HVAC system, completely walked through all possible options to make it perfect and extremely happy with every single employee that I came in contact with from Jon the owner, to Jordy the air flow expert to the installers Wayne and Kevin. Will only use them for service/maintenance/issues going forward. Long: We had a different AC company come out for a tune up, they said that our blower needed to be replaced and that there was mold found. It was going to be close to $1k to replace so I started looking at replacing the whole system since it was 10 years old. Comfort Monster came out and actually showed me the system and that there wasn't any mold or growth that he could find. He told me in his opinion the system looked exactly like a 10 year old system should and there wasn't anything that needed to be done. He stated flat out he wouldn't suggest doing anything instead of trying to sell me on anything. I work from home full time and it gets really uncomfortable so I made the decision to do it anyway. Jon was in contact with me and gave me an awesome price on an amazing system. Jordy came out and walked through everything I could do to improve the system from increasing/decreasing ducts in the attic to adding a media filter. I had never heard of a media filter, but went with it because I wasn't changing my filters in the 12 foot ceilings like I should have. Installers were awesome. So courteous, they actually put down a plastic strip up our stairs so as not to track anything. In addition put down protection under the attic so as not to damage the floors. Extremely happy with the whole experience, will be recommending them to everybody."

"Craig was knowledgeable, on-time, diagnosed the problem, explained my options and resolved the AC issue in a timely manner. We spoke for a few minutes after the work was completed and I found him to be a very kind and sincere person. I definitely recommend him and will call him in the future for HVAC maintenance."

"Can you give more than 5 stars? Landen's responses, communication and professionalism are top notch. Most recently, I had another company go out to diagnose a system that company installed back a few months ago because the thermostat wasn't working. After dropping the ball on two occasions, and then quoting me close to $1000 to run a new wire, I decided to call Landen. Carlos was quickly dispatched and within a half hour of arriving, had found the problem and had a fix in place! Holy Cow! Nowhere near the cost or ordeal that the other company was painting. That company was either inept OR they're crooks! Either way, never again. Learn from my experience...call the folks over at Landen and be done. Whatever you've got going on with your HVAC."

Heating and Air Conditioning questions, answered by experts

Yes. It's not just AC filters that get dirty. Ducts can accumulate dust and dirt quickly. Insects and animals can also get into duct systems, creating many problems. Dirt build-up and unwanted guests can constrict the airflow and cause rooms not to cool evenly. You might also see higher energy bills because they're not working as efficiently.

When your AC contactor goes bad, you might hear chattering or buzzing noises coming from your air conditioner. You may also notice that your AC is running but isn’t cooling your home. In some cases, your air conditioner might not even turn on at all. There could also be physical damage, discoloration, or corrosion around the contactor.

The cost of R32 refrigerant is about the same as the cost of R410A refrigerant, the most widely available type of refrigerant today. However, R32 systems use about 20% less refrigerant than R410A systems, making the refrigerant less expensive overall.

Choosing between a ductless mini-split and central AC depends on your specific needs. Ductless mini-splits are ideal for targeted cooling, providing zoned comfort and energy efficiency. They are perfect for smaller spaces or homes lacking ductwork. In contrast, central AC offers consistent cooling throughout the entire house but requires ductwork and may be less energy-efficient for smaller spaces. 

Consider factors like budget, home size, and cooling preferences to make the right choice. Combining both systems, with a ductless mini-split in specific areas, can also be a viable solution for tailored comfort and overall efficiency.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.
