I'm a Philly/South Jersey guy who knows your neck of the woods in Delco real well. I'm in the process of getting bids on replacing the HVAC system in a condo I just bought. I know I'm looking for the following:
1. A well made, dependable, furnace and condenser with up-to-date features.
2. A "FAIR" price on the equipment. I am also self employed, so I know we all need to make a living. No price gouging and no low-balling and then skimping on the installation to make up the difference.
3. Installation by qualified HVAC mechanics who take pride in the job they are doing and the quality of their work.
4. After the installation is complete, me having the feeling that the equipment and installation is top-notch and that I can depend on it for years to come, assuming proper care and maintenance. If something breaks, and things do break it's a fact of life, reasonable and reliable warranty service.
I might be living in a fantasy world, but my experience in business leads me to believe that if any HVAC or service dealer provides the HO with that type of service, they will have more business then they can handle.
