We are a full service heating and air conditioning contractor. We have 24 hour emergency service available. We currently have approximately 100 employees and we do not use sub contractors. Please visit our website at www.climatech.com for valuable offers and financing options.

"Terrible: 1) Installer did not install as agreed upon. Line was to be placed behind wallboard. They insisted it would not fit, but I found out later when I had another HVAC company install the same units at my work office and did place lines behind wall board behind 2x4's. Be honest will ya! 2) Installer damaged a valve in condenser causing unit to leak which needed replaced. I asked for a new condenser, but Climatech refused and repaired. and warranted the repair. I would have rather had new. 3) Installer split the copper line in two places. A 2nd installer had to come out several days after install to repair and finish install. I requested a new copper line, but they again refused, but instead warranted the repairs. I again wanted new. 4) They sale the unit as most quiet in industry, but when it get's below 40 degrees outside condenser hums and struggles over condensation. The inside unit gurgles and whistles and hisses over it as well. They had a Mitsubishi person come out. Their response is unit runs normal and the operations manual states that the noise is because of condensation and won't do anything further about it. I would have not ordered the unit knowing this. They should list this before selling it. Emailing me an operations manual after the fact of install and payment is just not an acceptable response. Neither Climatech nor Mitsubishi is showing any integrity nor addressing the noise problem. I would not use either again. I am exploring legal options and trying to develop a class action legal case over false advertisement to obtain a replacement unit to eliminate the noise or refund. Very disappointing to spend the one and get this from companies such as this. Email me for more information [email protected] Look at the pictures to see how bad their install looks in a finished room over the false position of their installer."

Heating and Air Conditioning questions, answered by experts

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected. 

Dry mode positively impacts indoor air quality by reducing excess moisture, which stops the growth of mold and mildew. By maintaining optimal humidity levels, dry mode creates a less hospitable environment for allergens and airborne pathogens, improving overall air quality. However, it's essential to ensure proper ventilation to prevent stale air accumulation.

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

Yes, adding central air can increase your home value by as much as 10%. Generally speaking, prospective buyers prefer a central AC system over a ductless system or room-by-room AC units. That’s because central air conditioning blends into the home easier than individual room air conditioners and typically has less equipment to maintain.

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.
