"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"

Heating and Air Conditioning questions, answered by experts

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned.

Not necessarily. Some portable air conditioners may be vented out a door, wall, or ceiling—or even into another room. It’s not necessarily dangerous to run a portable air conditioner without venting it, but it is counterproductive since the unit needs to vent the heat in order to cool the room down in the first place. Without venting your portable AC unit, you’re essentially running a dehumidifier and increasing the temperature in the room.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

It depends on the specifics of your warranty. The motor is likely not covered if you’re working with a limited warranty. The same goes for other components like the compressor and evaporator coil. Some extended warranties will cover the blower and fan motor, so read the fine print before signing up. Additionally, the manufacturer may offer a warranty for the parts, including the motor, though there’s likely to be a strict time limit for this coverage.

You should have your HVAC serviced at least once per year. A HVAC pro can perform maintenance twice a year if your unit is older or has many issues. You can expect to pay between $100 and $550 for HVAC maintenance, which includes a thorough tune-up, routine service, proactive and reactive maintenance, and emergency maintenance services.
