"I would absolutely recommend KO HVAC. Both Cody and Steve were extremely professional. They returned phone calls promptly and arrived on time. They are both quite knowledgeable. They were respectful of my home and left it neat and orderly at the end of each day. Steve thoroughly explained the systems when they were done. I am extremely satisfied with the entire experience."

"He showing up on time. He was very reasonable. It could have dressed a little more appropriate for the job, little more professional, and the price could have been cheaper. Was only less than 15 minutes, for 95 dollars."

"As SB Improvements has done for us before, excellent work was done. A new set of attic folding stairs was neatly installed and a new kitchen sink was also installed that same day. SB improvements patiently trimmed the countertop until the sink fit just right. Nearly a week later no leaks have been observed. As always the SB Improvements crew was polite and thorough, the work neatly done."

"If i could give zero stars i would have. We paid almost $12,000 back in October for them install a new system in our home. Since then we have failed county inspection 3 times. The techs who come out all have different stories and excuses. The electrician who came out last time Donald informed us of how terrible his own company was and how he planned to quit. Me and my mother have taken countless days off work for them to come bandaid the problems instead of fixing them costing us even more money for missing work. Last Monday we failed for the 3rd time so I reached out AGAIN to the cooperate office and here we are 7 days later with no response and issue still not addressed This will be reported to the BBB, Angie's list will be reported for false advertising because the reviews under this company's name are actually for a company they bought out action 9 will be involved if this isn't the last time I have to deal with these people. It's the most unprofessional experience I've had with any HVAC company and I'm very disappointed in how they conduct themselves and their business please home owners beware!!"

Heating and Air Conditioning questions, answered by experts

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

While all portable AC units will collect moisture as part of their cooling and dehumidifying process, whether and how often you need to drain them depends on what kind of unit you have and the natural humidity levels where you live. For example, if you live in a very dry area and have a self-evaporating unit, you may not need to drain your portable AC very often at all. Some units may automatically drain collected moisture out the window through their exhaust vent.

Yes, you can clean your air conditioner filter as a temporary fix for cleaning up dirt, but you’ll eventually need to replace it once the dust starts to accumulate. Use a vacuum with a hose attachment to clean your air filter at least once per year or more often if you have pets.
