Just finished up a routine, maintenance and tuneup on a Goodman natural gas powered unit that we installed a few years ago in the Middletown Delaware area. Noticed a leak coming from one of the drain lines, so I went ahead and repaired that for them, no cost to them. Everything else looked pretty darn good after some minor adjustments! All levels are pointing towards a healthy unit at this point. Thank you so much to Micah and his family for allowing us in your home and trusting us with your comfort.

Just performed a routine maintenance and tuneup on a two system home in Middletown, Delaware. Both systems were installed by us, one in 2018 and one last February. The American standard heat pump that we installed in 2018 was still standing great just needed both the indoor and outdoor capacitors swapped out. Client purchased 10 year parts and labor warranty, so this was covered completely. And the Goodman natural gas fire furnace that we installed last year is looking spectacular!

Just performed a routine, maintenance and tuneup on to natural gas fire furnaces in the Middletown Delaware area. One is an American standard that we put in about eight years ago and the other one is a York that was put in about 18 years ago. Everything was working fine for both units but deafly had some recommendations for both as well. Some additional maintenance is required, in my eyes, but like I said, everything is working.

Just completed a routine, maintenance and tuneup on a five year old carrier, natural gas furnace in Middletown, Delaware. Through testing I figured out that the income and gas pressure was very low, after trying to adjust it through the regulator, I realized that they have an issue with their income and gas pressure as a whole. I informed the client to contact their gas company to get this all situated. Everything else so perfect and all signs point towards a very healthy unit!

Just finished up doing routine maintenance and tuneups on two Goodman natural gas fired furnaces that we installed four years ago in the Middletown Delaware area. Everything was looking perfect for both units and need to know adjustment just a quick wipe down and to make sure all levels were reporting towards a health unit. On the downstairs unit, I did find a small condensate leak from the exhaust flue piping. This client purchased 10 year parts and labor warranty so this will be completely covered and at no cost to them! Will be back within a week to get that done fixed for them.

Just performed routine maintenance is in tuneups on two units for one home. One was a Goodman natural gas fire furnace that we installed last year. And one was a Bryant installed in 2008 by another company. The Goodman look perfectly fine after a quick gas pressure adjustment and good wipe down, everything was looking great. We have some airflow issues we have to resolve but that’s for another appointment. The Bryant had the wrong size capacitor, and gas pressure was super high. After those adjustments and a good vacuum and wipe down, everything was looking copacetic. Thank you so much to Troy for long is in your home and trusting us with your comfort.
