"Happy Holidays all! Please use my Holtzople (H) review to help you address your HVAC needs! Last summer, my Trane AC unit failed. Corey W (H) was the tech that came out to the house and troubleshooted/resolved the problem (leaking refrigerant). He also advised on probability of future repairs. Sadly, the unit performed well for only a short time before failing. It was time to consider my options. Repairs were becoming more frequent and costly. Tyler (H System Designer) visited and walked around my house inspecting my current HVAC system. We discussed repairing or replacing my ailing AC unit. He recommended replacing with a split ductless system and emailed a quote for 1. Enhanced Mitsubishi hyper heat mini split system (system) 2. Favorable financing options - low interest rates and affordable monthly payments. The install took a week. H’s crew arrived each morning, respected my property, and worked as a team to carefully install the new system. With gratitude, John"

"They were prompt and very professional. They kept us informed during the entire process of cleaning our ducts and dryer vent. They also installed an air scrubber and the total cost was several hundred dollars less than the quote we received from an HVAC company. The HVAC company told us we needed mold remediationâ ¦. DuctGurus found no mold. We received great service so we will be using and recommending this company in the future."

"Not only did they replace my old oil system with a heat pump, they replaced my entire AC system as well. Much more efficient, included new thermostats which are operated via mobile devices, and gave me peace of mind. Recommended an appropriate heating and AC system, replaced everything and did it in an efficient manner. Much more reasonably priced than all other quotes, prompt service & quick completion of the task. Didn't try to talk over my head about things that I wouldn't understand, explained it clearly and effectively. Highly recommend to anyone needing any type of heating or cooling repairs or replacements."

Heating and Air Conditioning FAQs, answered by experts

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.

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.

The average life span of an HVAC system is 15 to 20 years. Even if your old air conditioner is still functional, it isn't as energy-efficient as a newer system (especially one with an Energy Star designation). Older HVAC systems aren't as efficient, and the 10-year mark is when you should start making full system replacement plans. Twenty years in, that plan should be well underway rather than waiting for the unit to die.

Yes. Getting a whole-house dehumidifier can help you save money on energy bills. How? Your home automatically feels cooler when there’s less humidity in the air (“It’s the humidity that gets ya!” is such a true statement). This means that you won’t need to run your AC as much as you would if you had all that extra humidity in your home.

The cost to repair an air conditioner averages around $350 to $450, but the price can range from $100 to over $3,000. The final cost depends on the type of air conditioner, the extent of the damage, and the specific parts that need replacement. For example, repairing a window AC unit typically costs between $100 and $250, while central air conditioner repairs can range from $300 to $3,000. A simple fix like replacing a dirty filter might only cost $10 to $50, but a major issue like a broken compressor could cost around $2,000 or more, potentially making it more cost-effective to replace the entire system. Due to the need for specialty tools and handling of refrigerants, repairs more complex than changing a filter are best left to a professional.
