"When I first had this company do small projects for me, I was impressed with the work, however, as the projects kept being done, he was always in such a hurry. He had so many customers to handle, he did not have time to really do a good job. He replaced a vanity in a bathroom, and cracked the drain pipe (2 inch crack). It was left. It began to leak and ruined my ceiling in my living room. So now all the plumbing and ceiling need replaced at my cost. He installed bead board on another bathroom along with trim. It was the worst job I have ever seen. I sat down and cried after he left. Again at my out-of-pocket costs, I now have a beautiful bathroom installed properly. He needs to be up front with customers that his scope of work does not include plumbing, electrical or fine carpentry. Horrible job..."

"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

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

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.

If you’re trying to buy a new AC unit, there are a few crucial factors to consider. Look at the cooling capacity, the available warranty, the energy efficiency, and the type of unit. A ductless unit will cost more up front but may be a more viable option if you don’t already have ductwork. Additionally, a unit with better energy efficiency will cost less to run overall, saving you money on your monthly energy bill. 

Yes. In fact, not only are AC tuneups worth it, but they’re actually necessary to keep your air conditioner in good condition, improve its efficiency, and potentially prevent major damage. Experts recommend getting a tuneup at least once per year. In most cases, you’ll want to schedule it during the spring so that you can address any issues before the hottest months of the year.

It depends on the size of the space you’re cooling down. If you’re looking for the most affordable way to cool an entire house over a long period of time, then central air will be more cost-effective. But when it comes to cooling down a couple of rooms or one floor, a window unit may be the cheaper option, with both a lower cost to install and less energy used to run.
