We live near Portland, OR and are planning to put in a new HP/cooling coil to supplement a Trane gas heater which we are going to upgrade to var speed fan (see previous thread). One of the big reasons for the upgrade is to deal with noise and increased dust that we are anticipating with some nearby new home construction in the coming year (4-6 units in the lot next to ours). We like to open the windows at night and cool days and could open the windows on the side away from the construction since construction is to be done only on the south side of our lot.
The question is - should we upgrade the air filtration with a whole house air cleaner ? Not too long ago I reviewed this subject and thought we could deal with dust by changing the gas heater filters more frequently and/or using better grade filters. The filters we use currently are the best the Trane dealer has and are not the el cheapo ones. The other option is to add an electrostatic/filter module to the system like Trane Perfect Fit ( Consumer Reports like Aprilaire 5000 and Carrier Aira better ) . I definitely don't want ozone and that's why I dismissed the idea of any electrostatic component earlier.
Your opinions are welcome.
