"We had mice in our HVAC ducts. Jesus from Northwest Duct Services promptly came out to give us an estimate and then scheduled the repairs and duct cleaning on a Sunday so that we could be rid of the mice as soon as possible. When Jesus and his helper did the work, they were very professional and cleaned up after the job was done. We couldn't have asked for anything better!!!"

"The tech Brett was very quick and accurate in diagnosing the problem. He even saved us about $150.00 when he shopped around for the furnace part. He was very resspectful and knowledgeable and gave us some tips to help with the furnace. He suggested that Focus Heating has a preventive maintenance program and he explained what that included. He was very nice and thoughtful. They were four hours late for the appointment but I think it was due to the fact it was the Friday before Christmas weekend and they were swamped with service calls. Brett apologized for being late and he looked tired like he had been running from one call to the next. He was very pleasant and explained what he had found. Nice to know that the techs at Focus Heating are not commission based so they do not try to upsale you or make unnecssary repairs to boast their commission. I would reccomend them to family and friends."

Heating and Air Conditioning FAQs, answered by experts

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

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.

Not if you have a standard unit. Because portable AC units actually work to dehumidify the room, you’ll likely need to drain the unit from time to time—but you won’t have to put water into it. There is, however, another type of air conditioner called a swamp cooler that requires water to operate. If you have a swamp cooler, you may need to fill a reservoir with water and potentially ice. But a swamp cooler is different from a standard portable AC unit.

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.
