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."

"I had a fifty year old furnace that provided its last breath on the coldest day of the year and John the owner saw to it that I was financed and gave me a very good price. It was flawlessly installed the next day by his courteous staff and they hauled away the old furnace too. Great job! Thank you."

"Originally very happy with their service, a bit expensive though. My issue is now, I found the cracked pvc pipe where water was going on my floor after the furnace install. I figured after $15k worth of work from them they would have caught something like this. I had to fix myself. I also was sold a whole house water filter, which I actually like. What I didn't like is they wanted to charge me $360 for a $130 part which I was able to change myself in 10 minutes, and I'm a woman who's never done it before. I believe they charge way too much money for the work they do. They're quick so it's obvious they're paid by the job. I overheard a worker say the faster they get done the more jobs they get. So it's quantity over quality. I would much prefer to have a single individual and not a company from now on. I also do not appreciate the AI bot answering service. I much prefer talking to a human. Will not be doing business again. "

"My warranty company scheduled my a/c repair. The tech cancelled be sure he said I lived in a campground which was not true. I called them when they didn?t show up saying they were an hour away. I called and even after I told them I didn?t live in a campground still canceled. My 82 year old mother sat by the door because she was afraid she wouldn?t hear them for an hour. I would not let them come back if they wanted to"

Heating and Air Conditioning questions, answered by experts

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.

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.

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.

No. With a ventless portable AC system, you don’t need to vent anything out the window—but it will be harder to circulate the hot air from the room without one, so you’ll need to come up with another solution, like placing a fan near a warm spot and facing it towards and open water to push the hot air out.
