"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."

"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. "

Heating and Air Conditioning questions, answered by experts

Your air conditioner can temporarily run with a dirty filter, but it won’t work as efficiently. It will need to work harder to blow cool air throughout the room or house, and this can eventually cause the air conditioner to overheat or die prematurely. It’s much more cost-effective to clean or replace filters than to pay higher utility bills each month and replace the entire AC unit more often.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

Is mold in an air conditioner dangerous? Running an air conditioner with mold isn’t safe because it can spread harmful mold spores throughout your home. These spores may cause respiratory problems, allergies, or aggravate asthma in household members and guests. If you suspect there is mold hiding in your air conditioner, it’s best to stop using the HVAC system until the mold is cleaned to avoid health risks and further contamination.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

Yes. It's normal for the AC compressor to cycle on and off intermittently in dry mode as it maintains the desired humidity level. The compressor cycles to prevent over-dehumidification and to maintain a comfortable indoor environment. This cycling behavior ensures efficient operation and optimal humidity control, contributing to the overall effectiveness of the dry mode function in your AC system.
