"This was an unusual situation. In talking to Phil, the owner; and Randy, the former owner, I was treated very fairly when I brought my situation to their attention. Though it took awhile to coordinate communications between them and myself (busy schedules), once they surveyed the situation, they were very responsive. Their supervisor for system installation, Perry Allen, reviewed my HVAC system and came up with a great solution to the problem. He returned with all the required supplies and worked hard to ensure I had the proper solution. Perry was absolutely terrific (his colleague too). He not only wanted to fix the problem, but to do it the best way.
I'm very pleased with Gand M Service Company and would highly recommend them for new HVAC systems as well as service contracts.

"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

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with. 

You should only run your dehumidifier in warmer months, such as spring and summer, to get the best performance out of your system. The air gets drier when temperatures drop in the winter months, creating less of a need for a dehumidifier. However, when to run a dehumidifier will depend on your local climate.

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years
