"They told us "Our dispatch fee to come out is $39 and we waive that towards any work or repairs, including diagnostics." The electrician went to check and stayed at the property for less than 5 mins after confirmation to do full diagnostic of the electrical system. I don't think less than 5 mins is enough to run a full diagnostic and later on advise to upgrade the whole panel."

"2 new systems, 1 ERV, 2 Dehumidifiers, New Duct work, and Insulation replacement, scheduled to begin July 5, signed on June 14. They didn't complete work until the end of October and it took a demand letter from us to get it done. Were told we'd be their "case study" for ERV installation after this because they "didn't do a lot of them" when we were assured at the point of sale that they could do this. Still above-average humidity in the house, still have high utility costs. We finally fired them after a second chance in February of the following year when we were told they had parts for a job and would be out between 8-12 and, when calling them at 9:45 learned their tech was going to "get the parts" for his first stop (us). We didn't get a notification they were on the way until 11:15 and they were an hour and 45 minutes out. We're still using them for warranty work and now the system, not even 2 years old, has died. It's hot, and they'll be here in 3 days to look at it."

If you’re replacing an old AC system with a new unit, you can usually clean and repair the old ductwork without having to conduct a full replacement. Cleaning HVAC ducts typically costs around $400, while repairs range from $200 to $1,000. In contrast, installing new ductwork can range from $1,000 to $5,000, making it far more costly than cleaning or fixing existing ducts. HVAC installation costs an average of $7,000 to replace a full system, so staying on top of maintenance and repairs is important.
AC cost efficiency depends on the size of your space and your long-term plans for your home. If you only need to cool a small area, a portable AC unit has a low upfront cost. Heat pumps are typically the most cost-effective option if you want to cool an entire home or improve the resale value. They provide strong cooling while being energy-efficient, which saves you money on your utility bills compared to most other AC types.
Installing a central AC unit typically takes four to eight hours if your home already has ductwork in place. However, if new ductwork needs to be installed, this can add another one to two days of labor to your project.
