"It was covered under warranty. They actually installed our HVAC and it just wasn't cooling and it was a real simple thing that he was able to fix me up with. I have know them and used them for a long time. They are always prompt. They are very professional in what they do. They pick up after themselves. Very helpful in the information that he provides and making sure that any issues we are dealing with, he takes care of."

"I sent a message through Angies List and they responded almost immediately. I was called and given a 30 minute window of their arrival, plus the technician's name. Then the technician called me when he was on his way. He talked to me then went to work and immediately diagnosed the issue (chipmunk chewed the wiring argh!). He gave me a quote which I felt was quite reasonable and the repair only took about 45 minutes. After that, we spoke further about the Hvac (it's pretty old), he said it seems to be running well but obviously has some age to it. He advised I don't need it replaced but may want to consider some ongoing maintenance. He was nice and professional and answered all of my dumb questions. I would definitely call them again.

"We recently had a brand new HVAC system installed by Chisholm, and the entire experience was excellent. From the initial consultation to the final walkthrough, their team was professional, knowledgeable, and easy to work with. They took the time to evaluate our home and helped us choose a system that fits both our space and our budget. The installation crew arrived on time, worked efficiently, and made sure everything was cleaned up afterward. They also took the time to explain how the new system works and answered all our questions thoroughly. Since the install, the system has been running smoothly—quiet, efficient, and keeping our home consistently comfortable. We’ve already noticed an improvement in both temperature control and air quality. If you’re in need of HVAC work, I highly recommend Chisholm. They’re honest, skilled, and truly care about the quality of their work and customer satisfaction."

"Had an issue with a system 5 Star installed in August (7 months ago). They came out in 3 hours, and in 5 minutes realized that an electrician (separate project) had flipped off the wrong breaker. Had me up and running immediately. Cannot recommend 5 star enough for all HVAC work"

Heating and Air Conditioning FAQs, answered by experts

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.

When an evaporator coil becomes faulty, it can result in various problems within your HVAC system. These problems could include reduced cooling or heating capabilities due to ice formation and obstructed airflow, along with increased energy consumption and higher bills. Additionally, a damaged coil may lead to refrigerant leaks, which are environmentally harmful and decrease overall system efficiency.

Ultimately, if not addressed right away, a bad evaporator coil can even lead to a complete failure of your HVAC system. That’s why timely repair or replacement is crucial to maintaining your family’s comfort and your HVAC’s efficiency.

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

AC drip pans last five to 20 years, depending on the material. Plastic AC drip pans last five to 10 years, while metal pans can last over 10 years. Plastic AC drip pans are vulnerable to cracking in response to temperature changes. Metal drip pans are prone to rusting over time, which can also lead to leaks.
