"Outstanding Service & Integrity My boss’s tenant noticed an AC leak on Sunday, so I reached out to multiple AC repair companies that day, 30 minutes later, Kaldess AC replied to my text and they could send someone over the next morning at earliest. A technician was at the condo first thing Monday morning—less than 24 hours later! Throughout the process he kept me updated with clear ETAs, which was a huge relief since I was coordinating everything remotely for my boss. Once on-site, he called to explain what he found: a clogged drain line. He cleaned it, but when the unit still leaked, he dug deeper and discovered a more complex pipe issue. Knowing I’m no HVAC expert, he followed up with a detailed text (complete with pictures) so I could relay the exact problem to a plumber and give my boss a precise status report. The best part? He didn’t charge us a cent for the visit or the drain cleaning because the ultimate fix required a plumber instead of an AC repair. That level of honesty and professionalism is rare. If you want responsive communication, thorough diagnostics, and technicians who genuinely put customers first, call Kaldess AC ! Highly recommended!"

We are general contractors, but we also provide the following services: roofing, room additions, kitchen remodeling, bathroom remodeling, windows and doors and so much more.

"Buyer beware!!! I have never had such a nightmare with this company. Save your money and your sanity. They installed a patio cover for me. It leaked immediately. This was two years ago. For the past two years, they have been out at least 7 or 8 times claiming to "fix" the leaks. The leaks were not normal patio leaks by the way. The leaking has cause 3 of the 4 lights installed in the patio to fail. Every time they come, it's never fixed. The leaks keep getting worse. They never follow up with me, I always have to call them. They do not manage their sub contractors at all. This latest round started just before Christmas 2021, it's now been three months, four visits later. They took flashing off, said they were going to let it dry out and put it back. I didn't hear from them for two weeks, I noticed rain on the weather , I called Trig who had to send them back out to put the flashing back on. They sent some guy to do some more drastic sealing or something on my roof, they claimed it was done.....see attached photos of how they left my roof claiming it was done. Also, never followed back up with me on a light they need to replace which is still burned out and filled with water from rains. Save yourself the headache please!!! This still isn't resolved. I have filed a BBB compliant to try and help me resolve."

Heating and Air Conditioning questions, answered by experts

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

The best way to save money on HVAC repairs is by regularly having your system inspected and maintained. This can prevent bigger problems and costly repairs and replacements in the future. It’s also smart to buy quality equipment and hire companies that provide warranties on equipment and labor. If you need repairs, you may be able to save money by cashing in on rebates and incentives or keeping the area around your HVAC unit clear to shorten the time your contractor needs to spend in your home.

HVAC systems should be serviced annually, no matter which type of system you have. This service visit should include an inspection, cleaning, and regular maintenance tasks, like flushing the boiler. The best time to do this varies on the system. For heating-based systems, call in a technician sometime during the fall. For air conditioners, go for the spring. Basically, schedule the service call before you plan on amping up HVAC system usage for the season. 

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

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.
